NUTRICEUTICALS

An Introduction and Overview with Practical Clinical Applications

Learning Objectives To learn the definition of nutriceuticals

(nutraceuticals) To review the most popularly-used over-

the-counter nutriceutical preparations To gain understanding of and become

familiar with several dietary programs To know the special issues about athletes’

ergogenic and dietary programs

Learning Objectives To be familiar with several primary care

applications of nutriceuticals and review the pertinent supporting literature

To have a useful resource list for information about nutritional therapy to be better able to address patient questions in this area

Dr. Andrew Weil’s Anti-Oxidant Cocktail 100-250 mg of vitamin C and 25,000 IU of

mixed carotenes at breakfast 400-800 IU of natural vitamin E and 200

mcg of selenium at lunch 100-250 mg of vitamin C at dinner

Concerns Standardization Purity Potency Bioavailability FDA’s role

Remember FDA neither establishes nor regularly

enforces any standards of quality for herbs or other dietary supplements

Nutritional supplements and herbs are technically unapproved drugs, in an OTC limbo

Best advice: obtain a standardized extract marketed by a reputable firm

Nutriceuticals for Common Problems in Primary Care

Anti-oxidants Oxidant by-products of normal metabolism

result in extensive damage to DNA, proteins and lipids, leading to aging and degenerative diseases including cancer, cardiovascular disease, immunoincompetence, brain dysfunction and cataracts.*

Low intakes of fruits and vegetables double the risk of many types of cancer versus high intakes.

*Proc NY. Acad Sci. 1993; 90: 7915-7922

Vitamins C and E

Pretreatment with vitamin C and E prevented a fall in vasodilation which occurred after a high fat meal. No such fall was noted after a low fat meal.*

*Plotnick GD, Corretti MC. et al. Effect of Antioxidant Vitamins on the Transient Impairment of Endothelium-Dependent Brachial Artery Vaso- Activity Following a Single High-Fat Meal. JAMA.1997;278(20):1682-1686.

Vitamin E High risk CV pts. had “no apparent effect”

from Vit E (NEJM, 2000;342:154-60). No significant adverse events

Preventive effect suggested in Stampfer, Rimm studies (NEJM, 1993; 328)

Intermittent claudication Vit E found useful (Goodwin, Ann Int Med, Nov 1997)

Coenzyme Q10

CHF - Stroke index at rest and work improved significantly (p< .05), the pulmonary artery pressure at rest (p< .05) and work decreased and the pulmonary capillary wedge pressure at rest and work decreased (p< .05) with CoQ10 100mg bid*

*Munkholm H, Hansen HH. Coenzyme Q10 treatment in serious heart failure.

Biofactors. 1999;9(2-4):285-9

Vitamin B6

27/28 patients diagnosed with idiopathic CTS improved substantially on B6, 100 mg/day vs placebo. ¼ of patients were noted to be pyridoxine-depleted based on serum studies.*

*Carpal Tunnel Nutr Rep Int.1986 34(6):1031-40

Osteoarthritis--glucosamine sulfate, chondroitin sulfate

Drovanti A, Bignamini AA, Rovati AL. Therapeutic activity of oral glucosamine sulfate in osteoarthritis: a placebo controlled double blind investigation. Clin Ther 1980;3(4):260 72

Morreale P, et al. Comparison of the anti-inflammatory efficacy of chondroitin sulfate and diclofenac sodium in patients with knee osteoarthritis. J Rheumatol 1996; 23: 1385-91.

Recent studies on Glucosamine

McAlindon, TE, et al. Glucosamine and chondroitin for treatment of osteoarthritis: a systematic quality assessment and meta-analysis. JAMA 283(11): 1483-84. Feb 2000

RPC study showed reduction in cartilage loss and symptoms of OA over a 3 yr period in 106 pts (Reginster, Jan 2001 Lancet)

Meta-Analysis of Glucosamine and Chondroitin for Treatment of Osteoarthritis, McAlindon, et al. JAMA.2000;283:1469-1475

Moderate to large effect size in 15 studies reviewed

Product quality issues? Publication bias? Efficacy “appears probable” Studies under way

Cholesterol--inositol hexaniacinate, Vit C and E.

Murray M. Lipid-lowering drugs vs. Inositol hexaniacinate. Am J Natural Med 1995;2:9-12 (review).

Belcher JD, Balla J, Balla G, et al. Vitamin E, LDL, and endothelium: Brief oral vitamin supplementation prevents oxidized LDL-mediated vascular injury in vitro. Arterioscler Thromb 1993;13:1779-89.

Obesity--Ornish, vegetarian diet, chromium Gould KL, Ornish D, et al. Improved stenosis

geometry by quantitative coronary arteriography after vigorous risk factor modification. Am J Cardio 1992, 69:845-53

Integrating Nutritional Therapy Into Your Practice Standard of care Patient preference Safety vs efficacy Alternatives/options Integrative care/adds value

Ask the Unasked Questions

“What, if any, alternative therapies have you tried for this problem?”

“Considered?” “Have questions about?” “Besides these prescriptions, are you

taking any over the counter products, supplements, or herbs?”
