We all know about vitamins and minerals. But what do we really know about them? This article will give you a closer look at them.

It is best to obtain your vitamins and minerals, aka micronutrients, from whole, organic foods. This may not give us all that we need though, and supplementation is often required.

Vitamins are referred to as either fat or water soluble. The difference in them is dependent on what solution they dissolve in, i.e. fats/oils, or water.

Fat soluble vitamins are A, D, E, F, & K. They are stored in the body, so there is an increased risk for toxicity.

The other category, the water soluble vitamins; are the B-group, C, & P. They cannot be stored in the body. These vitamins are lost through the body through perspiration and urination. Because of this, it is essential for you to replenish these on a daily basis. If this is not done, deficiencies can occur.

We are used to the RDA as our way of figuring out what we need of each vitamin on a daily basis. This stands for the Recommended Daily Allowance, and has been in use since the 1940's. It is a standard dependent on only estimations, and assumes that we know all there is to know about micronutrients. These differ from country to country, and are the minimum requirements to avoid deficiency.

New standards have been proposed to update the RDA, this was back in 1993. This breaks vitamin requirements into different calculations, as follows: The RDA is still in there, but as Recommended DIETARY Intake, there's also the Adequate Intake Levels (AI), the Estimated Average Requirements (EAR), and the Tolerable Upper Intake Levels (UI).
