Vitamins are classified as water soluble and fat soluble. The former cannot be stored in the body, as they dissolve in water, whereas the latter can be stored in the body, as they dissolve in fats or lipids. The water-soluble vitamins are thrown out of the body along with the waste materials, regularly. Therefore our body needs to be replenished with these vitamins every day.

List of Water Soluble Vitamins
  • Vitamin B1 (thiamine)
  • Vitamin B2 (riboflavin)
  • Vitamin B3 (niacin)
  • Vitamin B5 (pantothenic acid)
  • Vitamin B6 (pyridoxine)
  • Vitamin B7 (biotin)
  • Vitamin B9 (folic acid)
  • Vitamin B12 (various cobalamins)
  • Vitamin C
Thiamine, riboflavin, niacin, and biotin are required for the production of energy. Pyridoxine plays an important role in amino acid metabolism. Various cobalamins and folic acid are essential for important metabolic processes, like the process of cell division. Pantothenic acid helps prevent skin conditions like acne, and a rare condition known as paresthesia (prickling or burning sensation of skin with no apparent long-term physical effect). Vitamin C has antioxidant properties that help reduce the effects of free radicals on the body. It lowers the levels of bad cholesterol, and strengthens the immune system. It is essential for maintaining and repairing the body tissues. It strengthens the blood vessels by promoting the absorption of calcium and iron.

Yeast, liver, eggs, and some vegetables contain B vitamins. Most fruits and some vegetables like broccoli, Brussels sprouts, cauliflower, cucumber, carrot, tomato, turnip, etc., contain vitamin C. These foods can be incorporated into daily diet to avoid vitamin deficiencies.

Vitamin A, vitamin D, vitamin E, and vitamin K are fat soluble, though they are structurally similar. They get dissolved in fats or lipids, which are then stored by the body for future use. In spite of a healthy diet, one may get affected by deficiency of vitamins, which are soluble in water. So, not only a healthy diet, but a balanced diet can fulfill their recommended dietary allowance. The aforementioned list can come in handy, and help you enjoy the health benefits through proper diet.
