DESCRIPTION
Vitamin C as Ester-C calcium ascorbate, buffered for tolerance, with the bioflavonoids quercetin and rutin plus grape seed extract.
Ester-C is the branded, buffered form rather than plain ascorbic acid, and pairing it with bioflavonoids reflects how vitamin C occurs in food rather than in isolation.
