Vitamin B2 (Riboflavin) > for dietary supplements

Vitamin B2 is also part of the water-soluble vitamins, which are offered by BTC Europe. Our technical experts can support you by developing your desired end-product.

Physiological importance

Riboflavin acts as a co-enzyme in a large number of oxidizing and reducing enzymes and thus plays a role in the transfer of hydrogen atoms during the energy generating oxidation processes within the cell, known as the respiratory chain. Therefore, riboflavin – along with other B-complex vitamins – acts as a coenzyme in the protein, fat and carbohydrate metabolisms, as well as in the generation of energy via ATP.
Furthermore, riboflavin is involved in the metabolism of other B-vitamins (folic acid, pyridoxine and niacin) and in the production of hormones in the adrenal cortex.

Consequences of a vitamin B2 deficiency

  • changes inside the mouth (inflammation of the mucous membranes, changes on the lips, tongue and in the gastrointestinal tract)
  • changes of the skin (seborrhoic dermatitis, dystrophia of the finger nails)
  • changes in the eyes (keratitis, opacification of the lens, vascularization of the cornea, cataract)
