Garlic can lower total and LDL cholesterol.

For those with high cholesterol, garlic supplements appear to reduce total and/or LDL cholesterol by about 10–15%.

Looking at LDL (the “bad”) and HDL (the “good”) cholesterol specifically, garlic appears to lower LDL but has no reliable effect on HDL.

High triglyceride levels are another known risk factor for heart disease, but garlic seems to have no significant effects on triglyceride levels.

SUMMARYGarlic supplements seem to reduce total and LDL cholesterol, particularly in those who have high cholesterol. HDL cholesterol and triglycerides do not seem to be affected.
