Water Soluble Vitamins B and C and their role in the body

What are vitamins? A vitamin is a small molecule that your body needs to carry out a certain reaction. Vitamins are essential in small quantities for all body functions including growth, repair of tissues, and the maintenance health. Most of us get enough of vitamins from our food, but it may be necessary for some people to take a vitamin supplement, because an ongoing shortage of vitamins will lead to failed health, weakness, susceptibility to disease. The body needs at least 13 different vitamins to function properly: Vitamin A - Retinol; Vitamin B complex (B1 - Thiamine; B2 - Riboflavin; B3 - Niacin; B6 - Pyridoxine; B12 - Cyanocobalamin; B9 - Folic acid; B5 - Pantothenic acid; H - Biotin); Vitamin C - Ascorbic acid; Vitamin D - Calciferol (can be obtained through sunlight); Vitamin E - Tocopherol; Vitamin K - Menaquinone. There are two types of vitamins: fat soluble (dissolve in fat) and water soluble. Water soluble vitamins Water-soluble vitamins are easily absorbed by your body.

These vitamins - vitamin C and all the B vitamins - need to dissolve in water before your body can absorb them. The water-soluble vitamins your body doesn't use are removed by your kidneys and come out in your urine. Because of this, your body can't store these vitamins in any significant amounts, so you need a fresh supply of these vitamins every day to avoid depletion. You can't really overdose on water-soluble vitamins, unless you take truly massive doses. Water-soluble vitamins are easily destroyed or washed out during food storage or preparation.
