Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Allicin is a sulfur-containing compound produced when garlic is crushed or chopped. Its use for supporting heart health is rooted in both traditional medicine and scientific investigation, but there is a moderate level of scientific evidence supporting its benefits. Several studies have demonstrated that allicin and other garlic-derived compounds may have positive effects on cardiovascular health. These effects include modest reductions in blood pressure, total cholesterol, and LDL cholesterol levels, as well as potential anti-atherosclerotic and antiplatelet properties. Some randomized controlled trials and meta-analyses suggest that garlic supplementation can lower blood pressure in hypertensive patients and slightly reduce cholesterol, though results can be inconsistent and the effect sizes are generally modest.

Mechanistically, allicin is thought to enhance the production of nitric oxide, leading to vasodilation and improved endothelial function. It may also inhibit platelet aggregation and reduce oxidative stress, contributing further to cardiovascular protection. However, most studies focus on general heart health and risk reduction rather than directly treating a "weak heart" (e.g., heart failure), and clinical guidelines do not recommend allicin as a primary treatment for heart disease. Thus, while there is scientific evidence supporting allicin's role in cardiovascular support, the quality and consistency of the evidence are moderate, justifying a rating of 3 out of 5.
