Fat-Soluble Vitamins vs Water-Soluble Vitamins

Vitamins are usually classified according to whether they are fat soluble or water soluble. Vitamins A, D, E, K, and CoQ10 are fat soluble. The rest in the vitamin list above are water soluble.

Fat-soluble vitamins need the presence of fats and certain minerals to be absorbed by the digestive system, and are stored mainly in the liver and fatty tissues. Since they are stored in the body, they do not need to be consumed as regularly as water soluble vitamins, but pose greater risk of toxicity when taken in excess.

Water-soluble vitamins, on the other hand, are not stored in the body in significant amounts. They are normally readily excreted in urine, and so must be replenished into the body daily to avoid being depleted.
