Vitamins are essential micronutrients that humans and animals need in small amounts for various roles throughout the human body. There are thirteen vitamins all together, some water soluble and some lipid soluble. We master them all.

Vitamins are divided into two groups: water-soluble (B-vitamins and C vitamin) and fat-soluble vitamins (A, D, E and K). Unlike water-soluble vitamins that need frequent supply, fat-soluble vitamins are stored in the liver and adipose tissues, and are eliminated much more slowly than water-soluble vitamins. In the blood stream, the fat-soluble vitamins are carried on proteins specialized for this task. Retinol (vitamin A) binds to retinol binding protein (RBP), vitamin D and its derivatives bind to vitamin D binding protein (DBP), whereas others like tocopherols (vitamin E) and phylloquinons/menaquinons (vitamin K) are carried by lipoproteins. The water soluble vitamins B and C flows freely dissolved in the water-phase of blood without the need of binding proteins. 

In Vitas we have worked with vitamin analyses for 28 years and our people are experts on the topic. We master a broad range of techniques used for vitamin determination from a variety of sample types, including blood, serum, plasma, tissue, milk, urine, etc.
