What is the difference in water soluble and fat soluble vitamins?
• There are two groups of vitamins, water-soluble and fat-soluble. Water-soluble vitamins (the 8 B vitamins and Vitamin C) can dissolve in water and be excreted by the kidneys. Water-soluble vitamins are not stored by the body (except for vitamin B12, which is stored in the liver). Fat-soluble vitamins (A, D, E and K) dissolve in fat and are transported by fat in the body. Excess fat-soluble vitamins are stored in the liver and fat tissue, and are not excreted by the kidney. Because of this storage, they can build up to toxic levels if too much is taken, especially vitamins A and D.
