SKIN: Vitamin C contributes to normal collagen formation of the skin & to the protection of cells from oxidative stress. Hyaluronic acid is a key component in the skin and is known to hold up to 1000 times it’s weight in water. This helps to maintain elasticity and skin tone. The body’s natural production of hyaluronic acid declines as we get older and it thought that supplementation can help to replenish levels and maintain healthy skin. JOINTS: Vitamin C contributes to normal collagen formation for the normal function of cartilage & bones. Hyaluronic acid is a protein found naturally in the body, particularly in the joints as a component of Synovial Fluid; a lubricant that reduces friction between the joint cartilage.
