Garlic is a superfood because it has so many beneficial properties:Garlic has anti-inflammatory benefits and helps blood flow more easily through the body. Several studies found that blood pressure was lowered by 10% when the participant took garlic supplements. Keep in mind that the supplement doses are fairly highâ600 to 1,500 mg of aged garlic extract. Thatâs the equivalent of roughly four cloves of garlic a day, so buy your fresh garlic.
