Determination of Vitamins

Jun 29, 2020

Vitamins are essential micronutrients necessary for the proper functioning of metabolism and immune system. Vitamin deficiencies can cause serious conditions & diseases that could affect long-term health. Since vitamins mostly cannot be synthetized in the organism, they must be obtained through food. Apart from fruit and vegetables, they are present in fish, meat, cereals, nuts and dairy products. In addition, some foods are artificially enriched with added vitamins and specialised food supplements are available on the market.

There are 13 types of vitamins considered vital for humans.
