Vitamin B2 (Riboflavin)
The yellow vitamin
Vitamin B2, also known as riboflavin, is the yellow vitamin and is used, among other things, as a natural dye. It is sensitive to light and helps the body's cells to produce energy. Like other B-vitamins, it is excreted via the urine, as it is water-soluble. B-vitamins are only stored in the body in small quantities.
In the event of a deficiency, there will often be a deficiency of most of the B-vitamins, so the supplement contains all B-vitamins.
Vitamin B2 is important to energy production, including carbohydrate and fat metabolism, muscle building and hormone production, as well as maintaining the mucus membranes. Thus, like vitamin B1, it has an influence on growth. In addition, it strengthens the eyes, hair, skin and nails, so a severe deficiency can therefore be seen in rashes, mouth wounds, oral inflammation, warts, surface damage to the tongue, and a number of irritations and diseases around the eyes. A mild deficiency will result only in fatigue.
Lack of vitamin B2 is most commonly seen in those who have poor nutrition, such as the elderly and heavy alcohol users. A deficiency can also lead to birth defects in pregnant women. You should therefore be aware that, if you are taking certain types of medicines, such as birth control pills and antibiotics, and if you are on diet (a one-sided diet, for example, fat free), the need for vitamin B2 is increased. In addition, coffee, sugar and alcohol reduce the absorption of vitamins in the small intestine.
You can find vitamin B2 in:
- Meat, including organ meats (liver)
- Whole grains
