Current evidence indicates that of the many available garlic preparations, Kyolic Aged Garlic Extract (AGE), manufactured by Wakunaga of America, is the most reliable and consistent in its efficacy. Published studies on the ability of garlic and garlic supplements to lower blood pressure in patients with untreated hypertension, show that AGE is better tolerated than garlic powder and that its efficacy in reducing blood pressure is superior to that of raw or cooked garlic.
