Mixed
Consuming raw garlic or commercial garlic supplements (powdered or aged extract) at standard-to-high doses for 6 months does not produce statistically or clinically significant reductions in LDL-C or other plasma lipid concentrations in adults with moderate hypercholesterolemia.
If you have moderately high cholesterol, eating garlic or taking garlic supplements (raw, powdered, or aged extract) at typical doses will not significantly lower your LDL cholesterol. While garlic is a healthy food with other potential benefits, do not rely on it as a primary treatment for high cholesterol. Focus on proven lifestyle changes and medications if prescribed by your doctor.
None of the forms of garlic used in this study, including raw garlic, when given at an approximate dose of a 4-g clove per day, 6 d/wk for 6 months, had statistically or clinically significant effects on LDL-C or other plasma lipid concentrations in adults with moderate hypercholesterolemia.
Why this rating
Large sample size (n=192), rigorous double-blind design, extensive chemical characterization of products, and 6-month duration.
