Vitamin C, also known as ascorbic acid is a water soluble vitamin. Humans do not make their own vitamin C, and cannot store it, so we can only obtain it through fruit, vegetables and supplements. Vitamin C is required for the synthesis of collagen, the intercellular glue that keeps skin, lungs, arteries, the digestive tract and all organs intact. A potent antioxidant, it protects against free radicals, pollution, carcinogens, heavy metals, and other toxins. It is strongly antiviral and mildly antibacterial. Energy cannot be made in any cell, brain or muscle without adequate vitamin C. The adrenal glands have a high concentration of vitamin C which is essential for stress hormone synthesis. Good food sources of vitamin C are: peppers, broccoli, brussel sprouts, potatoes, oranges and kiwi fruit.
