Vitamins are classified into one of two groups, fat-soluble or water- soluble, and the group a vitamin belongs to is determined by how the vitamin is absorbed. How each vitamin is absorbed is complex, but can be simplified. If absorbed directly through the intestinal lumen into the blood stream, the vitamin is classified as water-soluble. If absorbed along with dietary fat, and transported to the liver before entering the bloodstream, the vitamin is considered fat-soluble. Fat-soluble vitamins can only enter the bloodstream via the lymphatic system. Vitamins are responsible for hormone production and regulation, cellular functions, and overall homoeostasis of the body. Each vitamin has a specific function in the body and if the vitamin is absent, an individual can become ill, and possibly even die.
Water soluble vitamins are more numerous than their fat-soluble counterparts and include vitamin C and the many different types of vitamin B. Many water-soluble vitamins are heat-sensitive, and can be destroyed by cooking or processing, thus eating fortified or raw foods is important to getting enough of these vitamins.
Vitamin C, or ascorbic acid, is the most well known vitamin and obtained from many fruits and vegetables, such as berries, citrus fruit, and brassica vegetables. Ascorbic acid is easily absorbed into the bloodstream and utilized by the body, thus is a highly bio-available vitamin. Vitamin C is important in collagen production and rejuvenation, keeping skin and tissues healthy, metabolism of proteins and fats, and is a potent anti-oxidant.
