We are looking for people aged 18 to 65 in Adelaide to participate in a study investigating the effectiveness of nutritional supplementation in adults with mild hypercholesterolaemia. The aim of the study is to research ways to lower cholesterol without medication.

This study is taking place in Adelaide

To participate you must be able to attend two visits at our clinic based in Adelaide's CBD.

Background

Cardiovascular disease (CVD) remains the leading cause of mortality worldwide, accounting for approximately one third of all deaths globally. Reducing serum low-density lipoprotein (LDL)-cholesterol is the primary therapeutic target for reducing CVD risk. Plant sterols, bergamot juice extract and artichoke leaf extract have all individually been shown to reduce LDL-cholesterol while hydroxytyrosol has been shown to protect LDL from oxidative damage.

About this study

The study will evaluate the effects of daily consumption of a supplement on serum LDL-cholesterol in adults with hypercholesterolaemia compared to placebo over four months.
