Optimal Liposomal Vitamin C Plus by Seeking Health provides 1000 mg of vitamin C (sourced from Scotland) along with bioflavonoids and rose hips extract in a great-tasting liposomal liquid form. Vitamin C is needed by the body to support the immune system, connective tissue and skin, and to recycle glutathione. In the body, as an antioxidant, Vitamin C may help to protect cells from damage caused by free radicals. Environmental exposures to free radicals occur every day, from cigarette smoke, air pollution, and ultraviolet light from the sun. Free radicals are also produced as the by-products of normal metabolic processes. Additionally, the body needs vitamin C to make collagen, a protein required for healthy skin and normal wound healing processes.
