The importance of vitamin-C
Vitamin-C (ascorbic acid) is an essential nutrient that humans can’t produce (unlike most animals) and therefore we must obtain it through our diet or supplements.
It functions as an antioxidant in the body and helps mop up free radicals that are created as a normal part of cellular metabolism and immune function, protecting proteins, fatty acids, glucose and DNA material from oxidative damage.
It also plays a role as a cofactor for enzymes in a number of chemical reactions in the body, for example helping in wound healing, immune function and fatty acid metabolism.
Stimulate collagen production
Vitamin-C is necessary for the formation of collagen, an important protein of skin, scar tissue, tendons, ligaments and blood vessels. It is essential for the healing of wounds and for the repair and maintenance of cartilage, bones and teeth.
A deficiency in vitamin-C leads to a condition known as scurvy, resulting in poor wound healing, bleeding gums, joint pain and bruising, which can occur in only 3 months depletion of vitamin-C.
As we age, our body produces less collagen - the first signs of this are usually evident as loss of firmness in the skin.
Vitamin-C is perhaps best known for its role in the immune system and most people take it as a preventative measure for seasonal colds and flus.
Research suggests vitamin-C may be helpful in both the prevention and treatment of respiratory and systemic infections by enhancing various immune cell functions.
Endurance athletes, in particular, whose training places them under significant oxidative stress, have a 50% reduction in risk of developing a cold when taking vitamin-C prophylactically. Children also benefit from a significant reduction in risk when taking doses of up to 2 grams per day.
