Swanson Ultra EGCG is the ultimate green tea formula for cellular protection. For thousands of years, Chinese herbalists have treasured green tea as one of natures valuable health-supporting herbs, and for good reason. Modern scientific research has revealed that green tea contains a unique antioxidant constituent known as epigallocatechin gallate (EGCG), which has proven to be one of nature's most effective free-radical neutralizers. This powerful compound delivers outstanding protection for cells and tissues throughout the body, guarding them against the damaging free radicals that are largely responsible for the aging process. Swanson Ultra EGCG features GreenSelect, a super-potent, caffeine-free green tea extract that's standardized to deliver an impressive 275 mg of EGCG per capsule. It's an excellent all-natural high-powered weapon to add to your body's antioxidant arsenal.
