Vitamins are essential micronutrients humans and animals needs in small amounts for various roles throughout the human body. Vitamins are divided into two groups: water-soluble (B-complex vitamins and C vitamins) and fat-soluble vitamins (A, D, E and K). Unlike water-soluble vitamins that need regular replacement in the body, fat-soluble vitamins are stored in the liver and fatty tissues, and are eliminated much more slowly than watersoluble vitamins. In the blood stream the non water soluble vitamins are carried on proteins specilized for this task. Retinol (VitA) on retinol bibinding protein (RBP) , 25-OH-Vitamin D on vitamin binding protein ( DBP) while others like tocopherols (VitE) and phylloquinone ( VitK1) are carried in lipoproteins. The water soluble vitamins B and C flows freely in the blood stream without the need of support.

In Vitas we have worked with vitamin analysis for twenty years and our people are experts on the topic. We master a broad range of techniques used for vitamin determination from a wide range of sample types, including biological samples like blood, serum, plasma, tissue, milk urine etc. Some of these are listed below.
