Vitamins 

Vitamins are essential micronutrients that our body requires in small quantities.
They may be fat soluble (A, D, E and K) or water-soluble (vitamin B and vitamin C).

The B vitamins include vitamin B1 (thiamine), B2 (riboflavin) and B6 (pyridoxine), pantothenic acid, niacin, biotin, folic acid (folate), and vitamin B12 (cobalamin). For each vitamin was determined the daily recommended quantity (QDR), which is the daily quantity required to be wealthy. A person who consumes too little or too much of certain vitamins can develop a nutritional disturbance. 
Vitamins A and D become toxic when ingested in doses greater than 10 times the recommended daily amount, but it is the same with vitamins E and K (phylloquinone). Niacin, Vitamin B6 and Vitamin C are toxic when we take high doses, but the remaining water-soluble vitamins do not have this toxicity. 

Only two fat-soluble vitamins (A and E) are kept in the body in variable amounts; D and K do it in small quantities.
According to the needs, vitamin C is the one that lays in a fewer quantity and B12, on the other hand, is the one that accumulates the most. It takes about 7 years to spend all the reserves of the organism, which are 2 mg or 3 mg. 

 

Vitamins and minerals

Vitamins and minerals are a vital part of a healthy diet.

If a person ingest different types of food, the probability of developing a deficiency of these nutrients is very low. However, those who follow very strict diets may not ingest enough of a determine vitamin or a particular mineral. For example, strict vegetarians may have B12 deficiency, which can only be obtained from animal products. On the other hand, consumption of large amounts of vitamin and mineral supplements without medical supervision can have deleterious effects (toxic).
