Rating (out of 5): 3

Algal oil is primarily used as a source of omega-3 fatty acids, particularly docosahexaenoic acid (DHA) and, in some preparations, eicosapentaenoic acid (EPA). Its application in cholesterol management is based on research showing that omega-3 fatty acids can help modulate blood lipid profiles. While most studies have focused on fish oil, algal oil offers a plant-based alternative with similar omega-3 benefits. Several clinical trials have demonstrated that supplementation with algal oil can increase serum levels of DHA and, to a lesser extent, EPA, which may contribute to a modest reduction in triglycerides and potentially support maintenance of healthy cholesterol levels. However, the evidence specifically addressing the use of algal oil for treating low cholesterol (hypocholesterolemia) is limited. Most research focuses on reducing high cholesterol and triglycerides, rather than addressing low cholesterol. Nevertheless, omega-3 supplementation is generally considered safe and may help normalize lipid profiles, potentially supporting individuals with abnormally low cholesterol by promoting a healthier balance of lipid fractions. The American Heart Association recognizes the benefits of omega-3 fatty acids for cardiovascular health, but direct evidence for algal oil in treating low cholesterol is not robust. Therefore, while there is scientific plausibility and some evidence supporting its role in lipid modulation, the strength of evidence for using algal oil specifically to treat low cholesterol is moderate (rated 3 out of 5).
