SUBJECT CODES: Clinical Studies, Lipids and Cholesterol
This study was designed to determine the tolerability and overall e�ectiveness of a proprietary multi-ingredient, lipid-lowering supplement in subjects with dyslipidemia.
Aims
Method40 subjects were recruited for a single-center, double-blind, randomized, placebo-controlled trial. Study participants were recruited between December 2014 and March 2015. Initial screening included taking a medical history, physical examination, renal and hepatic function, serum lipid concentrations, serum electrolytes, complete blood counts, and urine analysis.
The study’s 40 patients were randomly assigned to receive either the proprietary multi-ingredient lipid-lowering supplement (PMILLS) or placebo. The trial consisted of a screening visit, a two-week run-in, and a four-month treatment period.
Samples were taken at baseline, one month, and four months of treatment.
Primary Outcomes
Secondary OutcomesDiastolic blood pressure decreased from 72.4 ± 9 mmHg to 68.1 ± 11 mmHg in the PMILLS group, while increasing from 72.3 ± 8 mmHg to 73.9 ± 9 mmHg with placebo (p=0.047) (see Table 2). Supplementation with the PMILLS group was also associated with decreased heart rate, from 67.5 ± 6 to 62.4 ± 7 (p=0.0093), which was significantly lower compared to the placebo group (see Table 1).
TNF-α, hs-CRP, and IL-6 were measured in serum. In the PMILLS group, participants with the highest inflammatory markers at baseline showed the greatest response to intervention, which was highly significant (hs-CRP; p<0.001: TNF-α; p<0.001: IL-6; p<0.001) (see Figure 3). These e�ects were not observed in the placebo group.
SafetyTwo of the recognized sides e�ects related to HMG-CoA inhibitor- based therapy are myopathy and serum coenzyme Q10 (CoQ10) reduction. None of the study participants reported any symptoms of myalgias or myopathy. There was also no significant reduction in serum CoQ10 levels at any time during the proprietary multi-ingredient lipid- lowering supplement group compared to the control group. (see Figure 4).
DiscussionThis PMILLS appears to be a safe and e�ective nutritional supplement for the management of dyslipidemia and its attendant inflammation. It o�ers an excellent alternative to individuals who are statin intolerant or who refuse to take statins or other lipid-lowering drugs. This PMILLS significantly reduced all of the atherogenic particles implicated in CHD, such as LDL, LDL-P, Apo-lipoprotein B, VLDL, TG and oxLDL. LDL and LDL-P, the driving risks for CHD (6)(10), both achieved significant reductions of 19.5 percent (p<0.001) and 5.0 percent (p=0.0492), respectively, with the PMILLS at one and four months.

Compared to the participants who received placebo, those receiving the PMILLS, had significant reductions in total cholesterol, LDL-C, and VLDL-C at both one and four months (see Figures 1,2, and 3). LDL-P decreased at four months in the PMILLS group, while no change was observed in the placebo group. Total LDL-III and IV particle number (LDL-P), an important indicator of LDL particle size. After treatment, oxLDL was significantly decreased in the PMILLS group, whereas, no change was observed in the placebo group (see Figure 4). Similar between-group changes were also observed for Apo-lipoprotein B and triglycerides (see Figures 5 and 6).
