Vitamin C, also known as ascorbic acid is a water-soluble vitamin that is an essential part of life. In its natural state, ascorbic acid appears in the form of a white to yellowish crystal or powder. Commercial Vitamin C is often a mix of ascorbic acid, sodium ascorbate and/or other ascorbates. Because the vitamin is water-soluble, it must be regularly replenished and is commonly found in fresh fruits, especially in the citrus family that is dominated by oranges, lemons, limes, and tangerines. Vitamin C is also abundant in green leafy vegetables. Vitamin C is a critical component of both basic body building functions and disease prevention. It is needed for the growth and repair of tissues in all parts of the body. Vitamin C is essential for the healing of wounds and the repair and maintenance of cartilage, bones and teeth.
