Vitamin B2 is one of the most abundant vitamins, both in the animal and plant world.
It exists in three-forms, one of which, riboflavin, is absorbed in the upper intestine, the other two being hydrolyzed in the digestive tract.
As it is not synthesized by the body, vitamin B2 must be taken in sufficient quantities through our diet to reach the recommended nutritional intake (men and women: 1.6 mg/day; nursing women: 1.8 mg/day). It is very widespread in the diet, particularly in animal products: calf's liver contains 3 mg/100 g; beef kidneys 2.4 mg/100 g; eggs 0.46 mg/100 g.
Like most other vitamins, vitamin B2 is involved in the mechanisms of energy production.
- Many of the functions of vitamin B2, some of which arise from its action on energy metabolism, have been scientifically proven. For example, it is not only necessary for physical and mental performance, but also for maintaining healthy bones, skin, hair and nails.
- In addition, other beneficial effects are attributed to it: it is said to be an antioxidant in its own right by helping to regenerate glutathione, which is degraded during its use by the enzyme glutathione peroxidase, a selenoprotein that helps to combat the free radicals responsible for oxidative stress. It is also believed that vitamin B2 is involved in the formation of red blood cells.
- Finally, it activates vitamin B6 and is essential for the synthesis of vitamin PP (vitamin B3) from tryptophan.
