Vitamin C supports healthy bones, muscles, blood vessels, and much more. Since the body cannot produce Vitamin C on its own, it must be obtained through diet or supplements. While fruits and vegetables are excellent sources of Vitamin C, it's not always possible to maintain a perfectly balanced diet to ensure optimal intake of Vitamin C in the right amounts or forms. Bio-C combines concentrated antioxidants with citrus bioflavonoids to enhance the absorption of Vitamin C in the body.
