Vitamin C plays an integral role in the formation of collagen. Collagen is a major structural protein, important for strong connective tissue to help maintain skin integrity and appearance. Vitamin C helps the formation of connective tissue and supports the healing process of minor wounds. The antioxidant properties of grape seed and vitamin C help protect against free radical damage. Grape seeds contain high levels of proanthocyanidins, a naturally occurring bioflavonoid, also found in fruits and vegetables. Grape seed helps relieve swelling (oedema), heaviness, pain and itching of the legs. Swisse Ultiboost Grape Seed has been formulated based on scientific evidence to provide a multi-purpose formula in a convenient dose. Please note: Limit of 48 per order.
