The Importance of Fat Soluble Vitamins
By John Gibb
While taking a multivitamin everyday is a good idea, some health professionals raise concern over the possibility of an individual ingesting more and minerals than their body requires. Many individuals don't worry about taking too many and minerals because they believe that any excess is flushed through the kidneys. This is one of the most common misconceptions related to vitamin supplementation.
There are 13 essential (A, C, D, E, K, B12, and the 7 B-complex vitamins). Each vitamin is either water-soluble or fat-soluble group. This is how are categorized. As referenced by their name, water-soluble (C and B-complex) dissolve in water and so any excess is excreted in the urine. Fat-soluble (A, D, E, and K) on the other hand are dissolved in fat that exists in the intestines and are eventually stored in the liver.
Since fat-soluble can remain in the body for an extended period of time, it is this issue that concerns health professionals. If an individual supplements their diet with and their normal diet provides
a sufficient amount of fat-soluble vitamins, there is the possibility that the excess amount of could cause toxicity. As the name implies, vitamin supplementation should only occur when there is a deficiency.
The need for vitamin supplementation is another issue with fat-soluble vitamins. Since water-soluble are used by the body or removed constantly, there is a regular requirement. Since fat-soluble are stored in the body, it is rare that an individual with a normal diet would ever require supplementation. The fact is, most people don't follow a normal diet. So, there is a chance that the concern that medical professionals have regarding these is moot. What seems to be more important is that people perform some research before blindly taking vitamins.
Nutrition experts recommend that an individual consult a medical professional before creating their own vitamin supplementation plan that includes fat-soluble vitamins. The doctor will undoubtedly order blood tests to determine if there is in fact a need for vitamin supplementation.
