Vitamin C provides antioxidant protection to the immune system, as well as maintains the health of blood vessels, tissue, cartilage, bones, eyes, and other organ systems.  Vitamin C is also required for the biosynthesis of collagen, L-carnitine, and neurotransmitters. The combined positive effects of vitamin C make it vital to the body's overall health. ‡Measure of acidity/alkalinity (neutral pH is 7.0)
