Vitamin C is necessary for normal growth and development. In addition, it is an important antioxidant that protects cells against oxidative damage and assists with respiratory responses to smoking and other pollutants. Your body is however not able to make vitamin C on its own. As it is a water-soluble vitamin, leftover amounts of the vitamin leave the body through the urine. This means you need a continuous supply of vitamin C in your diet. Vitamin C (as calcium ascorbate) is one of the most widely used supplements in the world. Future Health Vitamin C Assist's unique combination with broccoli, rosehip and acerola extract for optimal absorption makes it one of the world's leading buffered vitamin C formulas.
