Analytical Testing and Analysis of Vitamins

Vitamins are considered as supplements to a poor diet or supplements to prevent deficiency diseases. Vitamins are present in foods and foodstuffs of plant and animal origin. According to recommendations of the society of German chemist (GDCh), the tolerance for vitamins of group 3 (vitamin A, D, E, folic acid, vitamin B12 and Biotin) may be up to 30 % of the declared content, the tolerance for vitamins of the group 2 (vitamin B1, B2, B6, pantothenic acid, Niacin and vitamin C) are 20% of the declared content.


There are 13 essential vitamins, vitamins A, C, D, E, K and the B vitamins are divided into two groups: water-soluble and fat-soluble, vitamins of the B group and vitamin C, are water-soluble. Because the body is unable to synthesize most of these essential organic compounds, therefore it is vital to ingest the vitamins. Nonetheless, Vitamin D is an exception, because the body can form it with solar irradiation in the skin itself. Also Niacin can be formed from the amino acid tryptophan by metabolism. Each vitamin has a different function to help keep the body working properly.
