GGlobally, the population is getting older. The United Nations reports that the number of
older persons—those age 60 or over—will more than double by 2050 and triple by 2100,
growing to represent 3.1 billion people. And Europe has the greatest percentage of population
aged 60 or over—25 percent. In fact, the UN states: ‘Population ageing is poised to become
one of the most significant social transformations of the twenty-first century, with implications
for nearly all sectors of society.’
Certainly, the desire for youth has been a pursuit for time immemorial. It has driven the
interest in anti-wrinkle creams, glucosamine supplements and enteral nutrition. But today’s
older population isn’t interested in ‘anti-ageing’; it’s all about ‘healthy ageing’. The goal is to
remain as healthy and active as possible for as long as possible—increasing the ‘health span’
rather than focusing solely on ‘lifespan’.
This month’s issue around healthy ageing is designed to support your own ideation, offering
insights into ingredients and opportunities that may spark that next best-selling product. On
the ingredient side, our contributors dive into the myriad benefits of natural astaxanthin and
vitamin K2 (menaquinone-7). Both have potential applications in many areas, making them a
possibility to bolster existing formulations or drive a new concept. We also focus in on the
osteoarthritis market and the science supporting chondronutrients. And there’s a unique twist
on the supplementation side with a look at gamification of nutrition education; in today’s
digital age, finding a way to connect with consumers and keep that connection long-term
could build the brand loyalty that pays off over time.

Osteoarthritis
OOsteoarthritis (OA), one of the most disabling arthritic conditions, is a long-term chronic
disease. It involves movable joints characterised by cell stress and extracellular matrix degradation
initiated by micro- and macro-injury that activates maladaptive repair responses including the
proinflammatory pathways of innate immunity. The disease manifests first as a molecular
derangement (abnormal joint tissue metabolism) followed by anatomic and/or physiologic
derangements (characterised by cartilage degradation, bone remodeling, osteophyte formation,
joint inflammation and loss of normal joint function). The joint pain, swelling and stiffness
leads to activity limitations, participation restrictions, sleep interruption, fatigue and depressed
or anxious mood, and ultimately loss of independence and reduced quality of life.
What is osteoarthritis?OA is a disease of the whole organ—namely, the synovial joint. Cartilage is not the sole
tissue affected by OA; the subchondral bone and the synovial membrane also undergo
metabolic and structural modifications as the disease progresses.
OA is the most common form of arthritis and a major cause of disability, affecting 240 million
people globally. It ranks as the fifth highest cause of years lost to disability in high-income
countries, and the ninth highest cause in low- and middle-income countries. It accounts for 50%
of the entire musculoskeletal disease burden, and thus is considered the highest-burden condition
within the musculoskeletal group of diseases, which also includes rheumatoid arthritis (RA) and
osteoporosis. Radiographic evidence of knee OA is present in approximately 30% of men and
women over the age of 65. Worldwide estimates are that 9.6% of men and 18% of women over
the age of 60 years have symptomatic osteoarthritis. Approximately 80% of those with OA will
have limitations in movement, and 25% cannot perform their major activities of daily life.

The prevalence of OA is increasing, and with an increase in risk factors for OA, this is
expected to continue. The global impact of OA constitutes a major challenge for health
systems in the 21st century and in the coming years. Within the United States, the prevalence
of doctor-diagnosed arthritis is expected to increase in the coming decades—by 2030, an
estimated 67 million adults (25 percent of the projected total adult population) will have
doctor-diagnosed arthritis, compared with 52.5 million adults in 2010-2012.
Diving deeperThe most prevalent OA localisation is the knee joint, and symptomatic knee OA (KOA) affects
nearly one-quarter of the general population.
Different risk factors for the development of OA have been described as:
• general, unmodifiable risk factors (age, sex, genetic makeup),
• modifiable risk factors (obesity and hormonal factors), and
• local risk factors (prior joint anomalies and joint overload).
Notable among the main factors related to disease progression are joint alignment defects
and generalised OA.
A joint is considered a single organ, a functional unit composed of different tissues—mainly
cartilage, synovial membrane and subchondral bone—all involved in the etiopathogenesis of
osteoarthritis. OA has three fundamental manifestations: synovitis, destruction of the cartilage
and alterations in the subchondral bone (bone remodelling with subchondral sclerosis,
osteoarthritis and focal osteonecrosis).
At the level of the cartilage, a reduction in the number of chondrocytes is observed, mainly
by apoptosis (programmed cell death), which would be involved in different cellular mediators
present in excess in the affected joint, such as nitric oxide (NO), interleukin 1-beta (IL-1b) and
factor of tumor necrosis alpha (TNFα). These mediators can activate a series of proteolytic
proenzymes from the group of proteases, which contribute to the degradation of the
extracellular matrix of the cartilage, causing its progressive destruction.viii
There is also a component of synovial membrane inflammation in OA, caused by mechanical
overload of the joint and the presence of cartilage-degrading products. Throughout the
inflammatory process, released biochemical mediators have a destructive effect on the cartilage.
The subchondral bone generally increases in mineralisation along with the thickening of
subchondral tissues, and the appearance of bone spurs (growths along bone margins).ix
Beyond symptom managementUntil now, the management of OA has consisted mostly of symptom management—
essentially, reduction of pain and improvement of joint function—which relies on the
combination of pharmacological and non-pharmacological approaches, as has been proposed
by the main published guidelines. Although important, the control of symptoms is not the only
goal for OA patients. The ideal treatment for OA should preserve the joint structures, keeping
in mind the improvement in the quality of life of patients, and exhibit a good safety profile. It is
paramount to take into account the side effects due to the chronic use of OA therapies, such
as non-steroidal anti-inflammatory drugs (NSAIDs).ii
Osteoarthritis
7 Vitafoods Insights ■ Healthy Ageing: Opportunity of a Lifetime vitafoodsinsights.com
To treat the symptoms caused by OA, there are a number of medications ranging from
fast-acting analgesics, NSAIDs and corticosteroids, to opioids. All medications quickly improve
painful symptoms, but none are capable of modifying the evolution of the disease since the
same symptoms reappear after the medication has been metabolised by the body. In addition,
none are completely free from safety concerns (gastrointestinal, cardiovascular, hepatic, renal)
and could cause problems in so far as interactions with other medications.ii
Historically, the lion’s share of OA research has been directed toward studies on the
metabolism to the joint’s three structures: cartilage, synovial membrane, and subchondral
bone. However, as it has been described, OA affects all structures of the joint, including not
only the abovementioned ones but also the meniscus, the ligaments, the joint capsule, and the
periarticular muscle, without systemic effects, and is clinically characterised by the presence of
pain and limitation of joint function, crepitus and possible spillage.
There are specific products for nourishing the affected joint tissue, such as tendons,
ligaments, muscles, the synovial membrane and the subchondral bone.
Focusing on the synovium, it is increasingly observed that some degree of synovitis may
appear even in early OA and may be evaluated on magnetic resonance imaging (MRI) or
ultrasonography. So, the inflammatory synovium could be considered as a potential predictive
factor of structural progression in OA. The ability to detect synovitis may therefore be clinically
useful for a better understanding of pathogenesis and, possibly, for predicting treatment
response. In addition, early detection of synovitis may allow specific targeting of treatments.
The quality of the synovial fluid can play an important role too. Hyaluronic acid (HA)
represents one of the main components of this synovial fluid and contributes to its elasticity
and viscosity. The HA concentration in normal synovial fluid decreases with age, and it is well
known that in osteoarthritic joints, synovial fluid contains a lower concentration and molecular
weight of HA than in healthy ones. Thus, HA seems to play an important role either in joint
function or OA treatment and prevention and for this reason, hyaluronans are used for the
viscosupplementation of joints.
Collagen behaviourIt is well described that cartilage degradation can also occur as a result of the body’s immune
response to endogenous type II collagen, which is the primary structural component of
cartilage tissue. Collagen hydrolysate (CH) as a food supplement has the potential to improve
joint comfort and function. Collagen itself is a natural component of the diet, found in animal
products, such as meat and fish. However, the absorption of orally-ingested collagen that has
Osteoarthritis
The control of symptoms is not the only goal in OA patients. The ideal treatment for OA should preserve the joint structures, keeping in mind the improvement in the quality of life of patients, and exhibit a good safety profile.
8 Vitafoods Insights ■ Healthy Ageing: Opportunity of a Lifetime vitafoodsinsights.com
not been hydrolysed is poor. Collagen contains unique amino acids found in no other protein
(namely hydroxyproline and hydroxylysine). The use of CH, therefore, provides amino acids
specific to the collagen network, which could help to maintain the structure and function of
joint cartilage, thus improving joint comfort in a safe and efficacious manner.
CH has been shown in vitro to significantly increase biosynthesis of type II collagen in
chondrocytes in bovine and human cell cultures. Moreover, CH has been shown in vitro to
significantly increase biosynthesis of proteoglycans in chondrocytes in humans.lxix
There have also been several reports that a daily intake of 10 g/d CH for 60 days or longer
resulted in reduced pain in patients with OA of the hip or knee. This effect is due to a specific effect
of CH on joint tissues, since it is unlikely to have any analgesic or anti-inflammatory effects.lxix
Recently though, a more innovative collagen solution has gained popularity: native (non-
denatured) type II collagen. Native collagen differs from hydrolysed collagen in that it maintains
its three-dimensional structure that it would naturally have if endogenous, meaning that it
preserves the biologically active form of the molecule. This bioactive form of type II collagen acts
by curbing the body’s immune response to endogenous type ll collagen in the joint cartilage,
which is a totally different mechanism of action compared to the hydrolysed collagen. And
thanks to this, the native form shows activity at far lower doses than hydrolysed collagen.
This characteristic, immune-mediated, mechanism of action of the native type II collagen is
called oral tolerancexx-xxix and it comprises of a diminished immune response against
endogenous type II collagen: when orally taken, native type II collagen is recognised by the
immune system as an endogenous substance, blocking attacks from immune cells present in
the joint against endogenous type II collagen. Considering this mechanism of action, native
type II collagen may have positive effects on inflammation and degradation in joint diseases at
a very low dosage of only 40mg a day.lxxxi
Tough tendonsAnd finally, the importance of tendon health should be mentioned, as the tendon provides
structural support for proper joint function. Tendons are connective tissues principally made up
of type I collagen and specialised cells, called tenocytes. A tendon is a band of connective
tissue that connects muscle to bone and is capable of withstanding tension. Affectations of the
tendon are called tendinopathies, and can be caused by different factors (quick or sudden
movements, tendon overload, certain repetitive daily movements), and the main symptoms are
pain, inflammation and difficulty moving. Tendinopathies are the most common soft tissue
disorders. It is estimated that they affect the sedentary population and athletes.
The incidence of tendon injuries has increased substantially during the last few decades. It is
estimated tendon injuries account for one-third to half of all sports-related injuries. For some
years now, physical activity and participation in sports has been on a dramatic incline. More
people are making an effort to adopt a more active lifestyle as a means to stay healthy.
However, with the rise of the trend, joint problems have been more prevalent, and consumers
are looking for new solutions to maintain healthy joints and improve mobility. It is for this
reason that joint health must continue to be researched to find new ingredients, products, and
applications to respond to the population’s growing need.

I In 2012, the French national epidemiological survey OBEPI on overweight and obesity showed
that the way we eat is directly related to the risks of certain nutritional pathologies. Indeed,
this study shows, for instance, that the frequency of cardiovascular complications increases
significantly with the body mass index (BMI) of individuals—with 31.7% of obese individuals
having at least one cardiovascular problem, and seven times more diabetic individuals treated
in cases of declared obesity.1 Moreover, a recent study by the French National Institute of
Health and Medical research, INSERM, shows nearly one out of two French people is
overweight, and that global obesity is now approaching 16% of the population.2
Game onIt is therefore obvious that more public health nutritional interventions are needed to raise
public awareness about better eating habits and to prevent the risks related to nutritional
diseases in a more relevant way. It is in this context that a global nutrition policy has been
developed in France over the last 15 years, with the creation of the ‘Programme National
Nutrition Santé’ (PNNS). Despite a few encouraging results during the program, the last
evaluation of the PNNS 3 (2011-2015) revealed it needed more engagement and use of new
disruptive tools such as games or social media, in a more collective manner.3 It is in this context of
questioning and searching for new promising solutions for nutritional education that the science
of gamification and serious gaming comes into play, by postulating that a playful and social
approach would be more motivating and sustainable to change eating behaviours positively.

Despite a well-developed national nutritional policy in France, and a growing offer of tools
dedicated to the nutrition education and improved eating markets, it still seems very difficult to
change eating behaviours in an effective and sustainable way. Indeed, eating behaviours are
complex concepts to deal with, due to all the determinants that model and influence them.
Previously, literature tended to explain our behaviours and processes of change of eating
behaviours through a supporting theory that only a consumer can maintain control over his or
her decisions and choices of behavior.4 Lahlou explains it is difficult to move away from this
primitive model, but that basic human will is, however, only a determinant among so many
others and is not enough to explain eating behaviours by itself. According to this respected
author, it is well known that our eating behaviours are influenced by different techno-
economic, psychological and social underlying determinants. Indeed, consumers meet many
material constraints modeling their behavioural routines, along with cognitive bias determining
their own food representations, and various environmental and social spheres directly
influencing their behaviours. To try changing eating behaviours without considering all these
aspects and underlying determinants can be ineffective in the context of a nutrition education
intervention. Based on these observations, it is thus important to understand, above all, the
nature of a nutrition education intervention and the many determinants that make it an
effective, captivating and sustainable action to positively change eating behaviours. Literature
and previous experiments show interventions based only on the transmission of knowledge
about nutrition are not enough to generate eating behaviour change for targeted populations.
So, what does nutrition education need to go beyond a basic educational approach and speak
about impactful and engaging interventions?
Breaking it downContemporary nutrition education can now be judiciously defined as a combination of
educational strategies and environmental support to facilitate healthy eating behaviours and
food choices.5 To be effective and sustainable, nutrition education must essentially consist of
three fundamental elements:
• A motivational phase (aiming at increase individual motivation to act).
• An action phase (aiming at facilitating ability to act).
• An environmental component (aiming at supporting the two previous elements, especially the action phase).
Contento brilliantly exposes the main key elements of success facilitating an effective
nutrition education intervention:
• Focusing the intervention on the process of behavioural change.
• Identifying and addressing precise intermediate behavioural determinants.
• Relying on behavioural theories according to objectives of change.
• Addressing multiple levels for the intervention (individual or collective).
• Using interventional tools and strategies directly based from theories.
Among these key factors, it is particularly important to focus a nutrition education intervention
design on the intermediate determinants that influence and model change in eating behaviour.
Some are characterised as modifiable, such as food accessibility, or weakly modifiable, such as
Gamification
13 Vitafoods Insights ■ Healthy Ageing: Opportunity of a Lifetime vitafoodsinsights.com
the socio-economic situation or the level of education of individuals. It can be distinguished
biological or physiological factors (other determinants related directly to people and their
interactions), or factors from the environmental and social spheres as well.
Many different and complementary behavioural theories have addressed these underlying
constructs, determining the shift from inaction to intention, and vice versa. In nutrition
education interventions, some theories can be applied to address the motivational phase on
the one hand or the action phase on the other. However, it is essential to underline that any
intervention that neglects an effective motivational phase would be doomed to failure. But
how could the motivation and engagement of individuals be effectively enhanced in the
context of a nutrition education approach? That is precisely the reason why the hypothesis of
using gaming and gamification sciences as motivational strategies for nutritional education
seems relevant for this purpose. Indeed, it is important to remember that playing remains one
of the first socialisation means of humanity, and remains useful in many aspects of our lives.
Playful interaction is one of the very first natural vectors for learning that we experience from
birth.6 But why do people attach so much importance to games? Why does playing represent
such a vast field of possibilities in terms of people’s engagement? How could a gamification
approach be reconciled with effective nutrition education interventions? There are many
questions that gaming sciences could answer in a promising way.
Why do we respond to games? Gamification can be defined as the integration of concepts and constructs directly from
game mechanics into a neutral activity or non-playful objective such as nutrition education.
Among these elements, we find at the same time basic elements of any game like point
scoring, badges, results, leaderboards, scenarios, avatars and teammates.7 Certain authors also
identified fundamental concepts and intrapersonal values, such as the sense of achievement,
or self-efficacy.8 It is precisely these complementary elements that are essential in the process of
gamification because they are key components of motivational theories as well. For instance,
among these motivational concepts there is the self-determination theory, based on the basic
psychological needs of competence, autonomy and relatedness that would allow the
behavioural engagement of individuals.9
Competence refers to the feelings of efficacy and control experienced during the
achievement of an activity or task. This inner feeling relates to that of being able to perform an
action or task. This concept is, in a way, very close to the concept of self-efficacy—often
addressed in behavioural change literature and nutrition education science.
Gamification
It is particularly important to focus a nutrition education intervention design on the intermediate determinants that influence and model change in eating behaviour.
14 Vitafoods Insights ■ Healthy Ageing: Opportunity of a Lifetime vitafoodsinsights.com
As for the need for autonomy, it is essential and central in this theory: it refers to the feeling
of one being responsible for one’s own actions and accomplishing them either for personal
interest, or because these actions are in accordance with their intrapersonal values.
Finally, the need for relatedness translates as a feeling of being connected to others in a
certain way—of being part of an entity, or a group, agreeably gathered around an activity or a
cause. Thus, the previous set of gamification concepts could perfectly reinforce these basic
human psychological needs. Points and badges would, for instance, show the player that he or
she is gaining skill. The immersion of a scenario or the personalisation of an avatar will
reinforce the feeling of autonomy and self-realisation in an individual. All the other players in
the community will give the player that much-needed sense of relatedness and belonging.
In light of these theoretical observations, it seems more than relevant to consider gaming
strategies as a motivational vector to engage consumers in a process of positive eating
behavioural change. Underlying the concept of general gamification, the use of serious
gaming, and other videogaming devices represent great potential for nutrition education as
well. Unlike a basic gamification approach, serious games are exclusively developed towards
serious objectives, such as educational or behavioural purposes. Although there is still much
supporting research to be done in this area, some previous studies and serious games have
already shown encouraging results in terms of nutrition education and eating behaviour
change.10 Indeed, the Squire’s Quest! serious game, a playful program consisting of 10 sessions
and five weeks of multimedia games, showed an increase in children’s consumption of fruits
and vegetables, with one serving per day by the end of the intervention—although the total
consumption remained below the five daily servings recommended by the national nutritional
policy. This game focuses on the acting phase and the Implementation Intention Theory and
the setting of personalised objectives among other behavioural models.
Watch this spaceMuch work needs to be done in this promising research field to understand how to
develop effective interventions in nutrition education science with specific mechanics from
the world of games better. This is essentially the academic purpose of the whole research
program initiated by the French consulting agency, NUTRIKEO, since 2015 with the
development of the KOAM Initiative, in partnership with Bordeaux Montaigne and Paris 8
University. This unique and innovative research program aims at studying the impact of a global
nutrition education intervention at family level—based entirely on theoretical concepts from
serious gaming and gamification sciences, first focusing on motivational processes specific to
consumer behavioural changes. The original version of the program consisted of an online
platform, nutrition serious games for children and teenagers, a coaching mobile application for
parents, and a global family rewarding system. The KOAM Initiative programme will soon
conduct a three-month interventional pilot study to evaluate the impact of using gamification
elements through serious games and mobile applications on eating behaviour change and
different food behaviour determinants. This information will be gathered from behaviour
change theories such as perceived risks, benefits and barriers, subjective norms or self-efficacy.

The main purpose of this study is to assess whether gamification and family inter-personal
influence could enhance individual motivation towards positive and sustainable eating
behaviour change, according to national nutritional recommendations. All measures will be
performed through quantitative questionnaires, family logbooks, 24-hour recalls, and online
focus groups with a dietician. This research is the very first nutrition education intervention
assessing the impact of both gamification motivational factors and family inter-personal
influence on motivation and intention of eating behaviour change. This study will provide
precursory outcomes to assess the game design, the theoretical model or benefits and pitfalls
of the nutrition education approach and technical developments from the KOAM Initiative. The
development and assessment of the KOAM Initiative is part of a doctoral program supported

NNearly all countries are experiencing significant growth in the senior population, which is
projected to accelerate in the coming decades. According to the United Nations, one in eight
people worldwide was aged 60 years or over in 2015. By 2030, older individuals are projected
to account for one in six people globally, and this will jump to one in every five by 2050.1 This
trend is boosting demand for healthy ageing supplements as these populations seek preventive
strategies and nutritional supplementation to live longer, healthier lives.
What is ROS?Reactive oxygen species (ROS) is a collective term that includes not only oxygen-centered free
radicals, but also some non-radical derivatives of oxygen. ROS, otherwise known as pro-
oxidants, are formed as by-products of normal metabolism in our body when food is converted
into energy.2 Immune cells fighting bacterial infections also release ROS.3 Additionally, lifestyle
and environmental factors such as pollutants, smoke, stress, sedentary lifestyle, extreme
exercise, and the use of certain medications can all contribute to an excess of ROS.4
Oxidative stressA diverse range of oxygen-free radicals and other ROS can be formed in the human body.
The interplay between ROS and antioxidants is critical in maintaining good health. If the ROS
generated exceeds the protective effects of antioxidants, it can cause oxidative stress. In a
normal healthy human body, the generation of ROS and other free radicals is kept in check
through antioxidant defenses. However, when the body is exposed to adverse physicochemical,
environmental or pathological stressors, this delicate balance is shifted in favor of pro-oxidants,
and results in oxidative stress. Oxidative stress occurs when more ROS are generated than the
body’s natural defenses can counteract, which can damage cells, lipids, proteins and DNA.
From a biological point of view, ageing involves the accumulation of oxidative damage in
cells and tissues. Younger people are naturally better protected from free radicals and other
ROS through balanced activity of the mitochondria, efficient antioxidant and DNA repair
systems, and active protein degradation machinery. Ageing, on the other hand, is generally

accompanied by mitochondrial dysfunction leading to increased free radical production that, in
turn, leads to an overloading of the defense systems and oxidative damage of cellular
components.5 Oxidative stress and an imbalance of pro-oxidants and antioxidants can impact
several health issues such as oxidation of blood lipids (cholesterol and triglyceride), increased
risk of heart disease, cognitive decline, joint pain and stiffness, granular pigment accumulation
in retinal vessels, loss of skin elasticity, and thinning of skin layers, etc.
The ageing process is accompanied by numerous heath challenges, which vary from
individual to individual due to a number of factors, including genetics, lifestyle choices,
environmental factors, and life events—to name a few. Balanced nutrition is a key lifestyle
factor that helps support general wellness. Antioxidants are natural substances that help to
prevent the harmful effects of excessive ROS activity, and combat or delay cell damage.
Avoiding an excess of ROS, adopting a healthy lifestyle, and introducing astaxanthin into the
diet, can help to prevent oxidative stress.
How astaxanthin helps Natural astaxanthin belongs to a family of naturally-occurring organic pigments called
carotenoids. There are over 600 known carotenoids, such as lycopene, lutein, and β-carotene.
They are responsible for the bright red, yellow and orange colours found in many fruits and
vegetables. Natural astaxanthin is the main carotenoid in aquatic animals such as shrimp,
lobster, salmon, trout, and red seabream. It contributes to the pinkish-red color of their flesh.
Natural astaxanthin is also found in some birds such as the flamingo. Synthetic astaxanthin can
be produced by chemical synthesis using petrochemicals. Natural astaxanthin has been
extensively studied and has a breadth of science around its efficacy, safety and chemical
assembly, including isomers and esterification.
Although astaxanthin has a long history of use in the human diet as a naturally occurring
component of seafood, most people do not consume enough of it in their diet. For instance,
the US population consumes only two to three pounds of wild and farmed salmon per year,
with an estimated astaxanthin intake of 0.029 mg/d.6 This is about 200 times less astaxanthin
than the documented dose for health benefits, which ranges from 2 mg to 12 mg.7-13 The
microalgae, Haematococcus pluvialis, synthesises the highest amount of natural astaxanthin in
nature, which makes it an optimal choice for commercial production of natural astaxanthin.
Dry meal of Haematococcus pluvialis has been marketed as a dietary supplement in the United
States since at least 1999.8 There is enough scientific evidence, including human and animal
data, to support the safety of natural astaxanthin.15-18
Research continues to show natural astaxanthin is one of the most potent antioxidants
available. Studies demonstrate that when it comes to trapping energy from singlet oxygen—
one of the most common ROS found in the body—natural astaxanthin is 6,000 times more
powerful than vitamin C, 770 times more than coenzyme Q10 (CoQ10), 100 times more
powerful than vitamin E, and five times more powerful than β-carotene.9

The antioxidant properties of various antioxidants in vivo are strongly influenced by how they
interact with the membrane bilayer, their orientation, and location within the membrane.
Nonpolar carotenoids (such as β-carotene and lycopene) are located between membrane
bilayers and therefore may disrupt the intermolecular packing of the phospholipid
molecules.10-11 In contrast, polar astaxanthin spans the membrane with its polar end groups
extending toward the head group regions of the membrane bilayer. Astaxanthin position does
not modify the structure of constituent membrane lipids (Figure 2).12, 22 As a result, astaxanthin
acts as a chain-breaking antioxidant by stopping free radical chain reactions and scavenging
lipid peroxyl radicals. Furthermore, since astaxanthin spans the cell membrane bilayer, its
terminal rings can effectively scavenge ROS on the membrane surface, while its polyene chain
is responsible for trapping ROS in the interior of the membrane.22
Figure 2: Astaxanthin orients into optimal hydrophilic and hydrophobic position within cell membrane and acts as a chain-breaking antioxidant. Since astaxanthin spans the cell membrane bilayer, it can effectively scavenge ROS at the membrane surface as well as in the interior of the membrane
Astaxanthin advantagesAstaxanthin can use different methods to prevent oxidative stress. Astaxanthin counteracts
potentially harmful free radicals/ROS by trapping energy (quenching) and the transfer of
electrons, or through hydrogen abstraction (scavenging).19,21,12-14 Energy from the high-energy
ROS compounds can be transferred to astaxanthin by direct contact, and that energy is
converted to heat.21 In this process of quenching, astaxanthin remains intact so it can undergo
further cycles of singlet oxygen quenching. Singlet molecular oxygen is a strong pro-oxidant
that displays substantial reactivity towards DNA, proteins, and lipids.13
Natural astaxanthin is a highly potent scavenger of ROS, and thereby a valuable ingredient
for healthy ageing formulations. Numerous studies back astaxanthin supplementation for
supporting an active, healthy lifestyle regardless of age.

Astaxanthin
Astaxanthin supports cardiovascular health by improving blood lipid profiles. It also has a
protective effect against cholesterol and triglyceride oxidation.9-10,13 Natural astaxanthin helps
boost energy delivery, and in turn, helps the heart muscle contract strongly and efficiently.14
When it comes to skin health, human studies show that 6 mg/d of astaxanthin for six to eight
weeks may reduce wrinkles, water loss, and age spots.15 Astaxanthin also improves the
elasticity, moisture content and texture of the skin, and the effects seem to be enhanced when
combined with the application of astaxanthin topically.16 Astaxanthin supports normal healthy
skin by improving skin elasticity and moisture, and reducing wrinkle formation.16
One study demonstrated that daily astaxanthin supplementation improved cognitive health
and learning scores in healthy middle-aged and elderly subjects with age-related
forgetfulness.17 Another human trial suggested that astaxanthin may help protect against
age-related cognitive decline.18
Studies of individuals with age-related macular degeneration have demonstrated
significant improvements in retinal health when given astaxanthin and other carotenoids.19
Astaxanthin helps support eye health by reducing oxidative damage and improving blood
flow in capillaries.20,21
A growing body of clinically-validated evidence indicates the benefits of natural astaxanthin
for a range of target groups—from young, highly-trained athletes with increased ROS
production, to healthy middle-aged and senior subjects with weakened antioxidant defense
activity. Astaxanthin is a valuable functional ingredient that supports normal immunity, heart,
eye, joint, and skin health—expanding our healthy ageing options throughout life.
Health and wellbeing in older age are shaped by events, lifestyle choices, and
environmental factors throughout the lifespan.22 For instance, cardiovascular disease, high
blood pressure, and diabetes typically occur in individuals with an unhealthy diet and/or
sedentary lifestyle beginning early in life. Therefore, concerns regarding healthy ageing must
be addressed throughout life, and it is never too late to start supplementing with a powerful
antioxidant like astaxanthin.

Vitamin K2
VVitamin K2: Vital nutrient for every stage of lifeby Jim Beakey
Vitamin K2—particularly menaquinione-7 (MK-7)—is vital for all people in all stages of life—
from conception to the retirement home. Boys and girls, men and women of all ages benefit
from K2 for different reasons at different stages. The bone health, heart health and circulatory
system benefits of vitamin K2 create dynamic opportunities for virtually all consumer types and
market categories. In fact, vitamin K2 plays a role in seven or eight top supplement categories,
as diverse as children’s health, sports nutrition and healthy ageing. Synergistic bone and heart
health benefits complement four of the top five selling ingredients: calcium, magnesium,
omega-3 and multivitamin blend. K2 and vitamin D3 also depend on each another for optimal
effect, widening commercial opportunity.
K2 is an essential fat-soluble vitamin, just like vitamins A, D, E and K1, and most diets are
K2-deficient. K2 is the necessary co-factor for the activation of osteocalcin, the proteins that
incorporate calcium into bone. K2 also activates matrix Gla proteins (MGP), which bind excess
calcium to prevent hardening of the arteries and circulatory system. MK-7 is the mediator of
calcium. Working with D3, vitamin K2 ensures that calcium goes to where it is helpful and
away from where it can be harmful. This is a lifelong process, with K2 balancing the body’s
changing requirements for calcium throughout the different stages of life. Vitamin K2 is an
essential and important nutrient, which offers unparalleled commercial opportunity as it makes
its way to mass markets and all consumer groups.
Men and women in late adulthood: active autumn yearsBone health, maintenance and prevention
Late adulthood (ages 40 to 60) is, in many ways, the ‘sweet-spot’ for vitamin K2’s bone and
heart health benefits. While K2 is integral to the process that incorporates calcium into the bone
matrix all through life, the effects of K2 deficiency become more apparent in late adulthood.
Bones undergo a natural cycle of disassembly and regeneration approximately every seven years.
Specialised cells called osteoblasts and osteoclasts build up and remove old bone. When we
are young, new bone is created faster than old bone is taken away. Peak bone mass is reached
around the age of 20, then levels off and maintains a more or less stable plateau. Around the
age of 40, however, the balance tips in favour of the cells that break down bone—old bone is
then removed faster than it is replaced, and bone mass begins to decrease. For men, this is
a steady decline. For women, the drop off is steeper and accelerated
by the hormonal effects of menopause.
Bones become more porous, brittle and weak. The risk for
fractures increases and the body’s ability to mend broken bones
decreases. Despite this, many of today’s 40 or 50-year-olds strive
IN THIS ISSUE Astaxanthin p.17 Takeaways p.28 Table of Contents p.2
23 Vitafoods Insights ■ Healthy Ageing: Opportunity of a Lifetime vitafoodsinsights.com
to be as active as they were in their twenties. On the other side of the ledger,
a few decades of bad habits, such as smoking or drinking, can also affect
bone health—both cause calcium loss in bones. Finally, the risk of developing
bone-weakening diseases like osteopenia and osteoporosis increases during
the 40- to 60-year-old timeframe.
Vitamin K2 supplementation, along with calcium and vitamin D3, provides
‘bone insurance’ for late adulthood. Clinical studies demonstrate that vitamin
K2 supports bone growth1, reduces bone fracture risk2-3 and increases bone
mineral density compared to a control group.4 K2 MK-7 in late adulthood is
vital to support an active lifestyle and help prevent the development of more
serious bone conditions.
Heart health, maintenance and preventionCalcium requires balance and regulation in the body, and vitamin K2 is the
‘mediator of calcium.’ Too much calcium in the bloodstream, from diet or
supplementation, can be deposited in the cardiovascular system. Arteries and
vessels harden and lose flexibility, limiting their ability to expand outward. This
forces the heart to work harder to push blood through reduced-diameter
vessels, thereby increasing cardiovascular disease (CVD) risks. This calcification
builds over decades, affecting as many as one in three adults5, with the late adult years
marking a period of increased risk.
K2 also activates matrix Gla proteins (MGP), which bind excess calcium in blood to prevent
deposit in vessels and arteries. This action plays a preventive role in maintaining heart health.
Vitamin K2 can also reverse existing calcification and restore flexibility to vessels and arteries.6
K2 regulates calcium by transporting it to where it is needed (bones) and away from where it is
harmful (heart and blood vessels), reducing CDV risk factors and helping maintain wellness and
quality of life in late adulthood.
Other age 40+ benefitsVitamin K2 has shown other possible benefits relevant to the 40+ age group. K2 deficiency is
associated with lower testosterone7, and a study conducted on rats demonstrated a 58%
testosterone increase in blood and 88% increase in testes over a period of five weeks.8 Low
testosterone levels in men is considered a result of some age-related diseases. An association
between prostate cancer risk reduction and K2 has also been reported.9 K2 is also under
investigation for healthy skin, potentially as an anti-wrinkle agent. MGP activation may protect
the skin elastin fibres and the flexibility of small capillaries that supply blood to skin, allowing it
to remain supple for longer. K2 may also inhibit the mineralisation associated with varicose
veins10—both a health and a cosmetic issue for many. Finally, several lines of investigation
indicate that K2 may play a role in preserving health cognitive abilities and protecting the brain
from the damage associated with neurological diseases like Parkinson’s and Alzheimer’s.
K2 and the senior years: ages 60+Bone health: prevention of bone disease
Osteoporosis weakens bones, leaving them susceptible to fracture. Impact-related fractures
to the hip, wrist or spine are most common, but osteoporosis can leave bones so fragile that
even coughing can cause fractures. Bones begin to weaken when the rate of new bone

formation slows, and old bone is removed faster than it is replaced. This adjustment is natural,
occurs for all people, and results in a lower bone mineral density (BMD) over time. A critical
imbalance, however, leads to the onset of bone disease. Bone weakening begins decades
before the risk of clinical osteoporosis become apparent, and the pace accelerates markedly for
women over the age of 45.
Osteoporosis affects three times as many women than men and, within this group, women
have a higher fracture rate (40% for women vs 30% for men). Decreases in oestrogen levels at
menopause, as well as other genetic and environmental factors, put women at higher risk.
Women are more likely to cross the line from normal age-related bone weakening to disease
condition. Osteoporosis accounts for approximately 8.9 million fractures worldwide each
year—and incidents and related costs are rising. European healthcare costs for osteoporosis are
estimated to reach €47 billion per year by 2025.11 Greying populations will become
increasingly affected worldwide.
Japan, by exception, has lower rates of bone disease compared to western countries.3 This
has been attributed to higher K2 MK-7 content in diets.12 Japanese foods rich in MK-7 have
been correlated with a reduced risk of hip fracture in postmenopausal women2 and improved
BMD in elderly men.13 Another Japanese study showed that MK-7 reduced fracture risk for
both men and women.3
These Japanese studies on fracture risk are not the only evidence for MK-7’s bone health
benefits. A European study among women with osteopenia demonstrated that MK-7
preserved bone microarchitecture.14 Another study showed that daily supplementation of
MK-7 over three years (180μg) reduced declines in BMD and bone strength among post-
menopausal women.4 Although K2 is needed throughout life, much of the early research was
focused on at-risk populations. Now, over two decades of studies demonstrate the preventive
benefits of vitamin MK-7 in the fight against osteoporosis.
Heart health: the link between osteoporosis and CVDVitamin K2 regulates calcium in the body, directing it to where it is helpful and away from
where it can be harmful. Over time, K2 deficiency can manifest in the accumulation of excess
calcium in arteries and blood vessels in the form of calcium plaques. The circulatory
system becomes less flexible, causing the heart to work harder to pump blood
to where it is needed. Two of the leading causes of cardiovascular disease are
directly related to calcium build-up. Calcium, therefore, is a common factor
for both bone and heart health. It’s little surprise that studies demonstrate
associations between osteoporosis and CVD, and that the risk of one
may signify the risk of the other.15
Osteoporosis, for example, is correlated with the presence of calcium
deposits in blood vessels. Low BMD in postmenopausal women is also
linked to increased cardiovascular incident mortality. Vitamin K2’s duel
influence on calcium likely explains these associations. Calcium that is
not properly integrated into bones (through K2 osteocalcin activation) is
free for deposit into soft tissues and arteries. Supplementation with K2
solves this problem two ways: K2 helps integrate calcium into bones, and also
activates MGP to bind excess calcium to prevent deposit.
Vitamin K2
25 Vitafoods Insights ■ Healthy Ageing: Opportunity of a Lifetime vitafoodsinsights.com
Studies have shown that high levels of non-activated MGP are correlated with lower CVD
survival rates16, and that K2 supplementation increases activated MGP levels.17 An important
population-based study also demonstrated a 50% reduction in arterial calcification and
cardiovascular death, and a 25% reduction in all-cause mortality associated with K2 intake.18
Another study found a 9% reduced risk for CVD for every 10µg K2 increase.19 A 2015 study
demonstrates that MK-7 can even reverse existing calcification, restoring arteries and vessels to
a previous stage of health.6
Though the visible signs of osteoporosis and calcium-related CVD may only manifest in later years,
they develop over decades and there is a relationship between the two. Supplementation of
vitamin K2 helps preserve BMD, prevents calcium build-up in arteries, and reverses existing
calcification – ensuring health and longevity in the senior years.
The healthy ageing opportunityThe essential bone, heart and circulatory system benefits of vitamin K2/MK-7 create dynamic
commercial opportunities for product upgrade and extension for virtually all consumer types
and market categories. Vitamin K2 complements many top-selling ingredients, and most diets
are K2-deficient. Companies can therefore develop products that will transition along with
consumers from one life stage to the next, ensuring healthy bones, a healthy heart and the
pursuit of an active, fulfilling life.

Takeaways
ATakeaways for Your BusinessAs people increase in age, many fear the anticipated health setbacks that are typically
associated with getting older. Osteoarthritis (OA) remains the most common form of arthritis—
affecting over 240 million people worldwide. With a rise in the number of people participating
in physical activities, joint problems and injuries have also become more prevalent. Consumers
are looking for new solutions to maintaining their joints, improving their mobility and reducing
risk factors—as trauma to the joints is a well-known risk factor for OA. While the condition
itself and how to manage associated symptoms is well understood, there lies a gap for
products geared toward preserving joint structures—not only to reduce risk, but also to
improve quality of life. Medications to treat OA symptoms may cause fast-acting relief, but
none actually modify the evolution of the disease. Attention has historically been on cartilage,
the synovial membrane, and subchondral bone; but, specialists have noted that OA treatments
of the future will be focused on more granular factors, such as quality of synovial fluid,
innovative collagen solutions and preserving tendon health.
The idea of healthy ageing is not limited to preventing aches and pains—other parts of our body
experience stress, too. Few consumers know that the reactive oxygen species (ROS) in the body
should always be at a natural level. The body’s protective antioxidants can’t counteract an excess
of ROS (caused by environmental and lifestyle circumstances), and this leads to damaged cells, lipids,
proteins and DNA. Experts have found natural astaxanthin to be more powerful as a singlet
oxygen ROS scavenger than the popular likes of vitamin C, vitamin E, coenzyme Q10 and
β-carotene. Natural astaxanthin supports healthy bodily functions and lifestyle—regardless of age.
Daily supplementation has proven positive results, extending from cosmetic to mental benefits.
On the topic of lifelong supplements: vitamin K2 also shares the space of providing essential
nutrients through all stages of life. K2 works closely with other nutrients to carry out essential
processes throughout the body. However, experts have found most diets to be K2-deficient.
Especially toward and during the ‘golden years,’ K2 works to replenish and protect cells and
bones, as well as strengthen heart and blood circulatory function. While most consumers will
focus on more prominently-known vitamins, K2 complements many of these to create
additional benefits. Consumers will appreciate a vitamin K2 product that transitions with them
through their various stages of life.
None of these essential supplements will be any good if consumers aren’t educated about
the current and long-term benefits of leading a healthy, balanced and active lifestyle. When it
comes to a strategy for improving consumer education, experts are leaning toward gamified
approaches in the hopes to draw greater engagement and influence behaviour. The ability to
change eating and lifestyle behaviours has challenged nutrition specialists; however, tapping
into a market of educating consumers through interactive games (something most can relate
to) may be a likely solution for the future.
Increased awareness and education of what consumers can do for their bodies today will
only lead them to stronger, longer and quality lives—even during the years where most start
slowing down.
