Cholesterol levels may be lowered by garlic supplements

The most comprehensive study to date, including 39 trials, found the reduction in total and LDL cholesterol to be modest in comparison with statins but superior to placebo and with minimal side-effects.

An 8% reduction in people with cholesterol >5.5mmol/L is associated with a 38% reduction in risk of coronary events at age 50, the researchers said.

Aged garlic extract was more effective than garlic powder or garlic oil, their study suggested, however they could not make conclusions on dosage.
