Effects of a dietary supplement on cholesterol in subjects with moderate hypercholesterolemia

Prospective studies have demonstrated that the risk of death due to ischaemic heart disease is strongly correlated with blood cholesterol (TC) levels. Diet is the basic treatment for all dyslipidaemia. If diet alone proves inadequate, supplements can be used to try to reduce cholesterol levels. These substances are indicated in moderate dyslipidaemia, as they are able to induce a moderate reduction in blood cholesterol. The objective of our study was to investigate the effects of a dietary supplement containing Omega-3, Policosanol, Resveratrol, L-carnitine, Monascus purpureus, Coenzyme Q10, Vitamin B6 and Vitamin B12 on TC (primary end point) and LDL, triglycerides and HDL (secondary endpoints).

The study involved 40 men and 40 women recruited from the outpatient section of our Department randomly assigned to the treatment group (A) or the control group (B).

There was a statistically significant reduction in TC 6 months after the end of treatment in both groups. In Group A, there was also a statistically significant change in HDL, LDL and TG, while in group B, there was no statistically significant change in HDL, LDL or TG.

The dietary supplement used in our study, in combination with a balanced diet and physical exercise, was found to induce a significant reduction in TC and LDL-C and an improvement in HDL-C. In contrast, while a balanced diet together with physical exercise but without the dietary supplement produced a significant reduction in TC, it had no significant effect on the other lipid parameters tested.
