Vitamins are classified as either water soluble or fat soluble depending on how they are dissolved and absorbed by the body. Water soluble vitamins dissolve in water and are excreted through the kidneys since they cannot be stored. Fat-soluble vitamins dissolve in fat and are stored in fat throughout the body. Since they are more difficult for your body to dissolve and excrete, if you take too many of them they can build up to toxic levels.
It’s all about absorption
Fat-soluble vitamins are released in the small intestine during the digestion process and are absorbed through the intestinal wall into the lymph system. These vitamins are then transported by the bloodstream for use by the body or stored in the liver and fat cells when they are needed. On the other hand, water-soluble vitamins are absorbed directly into the bloodstream and those that are not used make their way out of the body.
Water soluble vitamins
These vitamins are obtained from our daily diet and from the vitamin supplements we take. However, the body can only absorb so much and the rest are flushed from the body so it’s no use taking copious amounts of vitamin supplements. They include vitamin C and the vitamin B-complex group: thiamine (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3), vitamin B6 (pyridoxine), folate (folic acid), vitamin B12, biotin and pantothenic acid. Then there is vitamin C.
Fat soluble vitamins
Namely vitamins A, D, E and K are only needed in small amounts and since they are stored, they are not required by the body on a daily basis. Because of their antioxidant qualities, vitamin A and vitamin E are the two that are particularly beneficial to the skin.
Synthetic vs. natural vitamins from our diet
The majority of commercial vitamin supplements are made using synthetic vitamins that do not perform the same functions in your body as vitamins found naturally in whole food. In fact, many synthetic vitamins deplete your body of other nutrients and tax your kidneys before being excreted through your urine.
Choosing a healthy balanced diet
