Vitamin C is an antioxidant that helps recycle vitamin E to support its antioxidant activity in the body and is essential for collagen formation and supports immune health. Bioflavonoids are polyphenol antioxidants that complement vitamin C and help protect the body against free radicals. Vitamin C, citrus bioflavonoids and their metabolites support blood circulation and cardiovascular health.
