China 95% Proanthocyanidins Pine Bark Extract

Pine bark extract is a concentrate of water-soluble bioflavonoids consisting of procyanidins, catechin, taxifolin and fruit acids in constant and normalized proportions. Because the bark is grown layer by layer over a period of more than 30 years, there are neither seasonal nor annual variations in the composition of its ingredients, in contrast to other herbal extracts. All constituents are potent scavengers of free radicals.
