Supplementation of Vitamin C is essential, since humans do not have the ability to produce it themselves. Vitamin C assists your body in making collagen, carnitine (which helps your body use fat for energy) and catecholamines (hormones made by your adrenal glands). Vitamin C is also used by the body for wound repair, healing, and maintaining the health of your bones, teeth and skin.These products have a strict internet policy -- please contact us for more information on prices and delivery.
