Vitamins are classified as either fat soluble (vitamins A, D, E and K) or water soluble (vitamins B and C). This difference between the two groups is very important. It determines how each vitamin acts within the body. The fat soluble vitamins are soluble in lipids (fats).
Fat-Soluble Vitamins. The fat-soluble vitamins are A, D, E, and K. Fat-soluble vitamins are absorbed in the lymph, transported in the blood, and can be stored in the liver and fatty tissues for use as needed. The fat-soluble vitamins are the ones you really need to be careful about.Because fat-soluble vitamins can be stored in the body, these vitamins can build up to toxic levels when consumed in excessive amounts.ll B vitamins and vitamin C are water-soluble. Water-soluble vitamins are easily dissolved in the body. The kidneys remove excess amounts of these vitamins so they can be excreted in the urine. Still, this doesn't mean that you can take vitamins B and C in unlimited quantities.
