Effects of Three Sources of Garlic on Plasma Lipids
Garlic supplements are the most consumed herbal products in the US and are frequently consumed to lower cholesterol. Despite garlic's popularity, this claim has not received adequate research support.
Study Design
The aim of this rigorous trial was to directly compare the effects of three different types of garlic preparations - fresh garlic and two commonly used garlic supplements - on serum lipids in subjects with moderately high LDL cholesterol levels.
Conclusions
The results showed that neither fresh garlic nor the garlic supplements, given at an approximate dose of a 4-gram garlic clove per day, 6 days per week for 6 months, were able to lower LDL cholesterol.
