Vitamin C is an antioxidant that helps protect cells from damaging.

Vitamin C also is needed to make and repair collagen, move fat into cells where it can be converted into energy and make neurotransmitters. The body also needs vitamin C to help wounds heal, improves the absorption of iron from plant-based foods and helps the immune system work properly to protect the body from diseases. Vitamin C is not evenly distributed throughout the body and the adrenal glands, pituitary gland, thymus, retina, brain, spleen, lungs, liver, thyroid, testicles, lymph nodes, kidney and pancreas all contain much higher levels of vitamin C than are found in circulating blood.
