Vitamin B2

Vitamin B2, also known as Riboflavin, is responsible for several processes in the body, an important one of which is converting the food we eat into energy. It also participates in the metabolism of many drugs and helps in the production of red blood cells.

Some good food sources of Vitamin B2 are Whole milk, cheese, green leafy vegetables; offal, such as liver and Kidneys, legumes, almonds mushrooms and yeast. Yeast extract is known to be an exceptionally good source of B2's Riboflavin. Although, wheat and other cereals contain fairly low concentrations of Flavins, in some parts of the world, where cereals are a staple component of diet, they are very important sources.


However the process of milling cereals, causes considerable loss of vitamin B2; and, due to this, white flour is routinely enriched by the addition of this vitamin. The enrichment of bread and ready-to-eat breakfast cereals contributes significantly to the dietary supply of vitamin B2, in the western world.

In humans the classical deficiency symptoms affect the mouth, a sore throat, inflammation of the lining of mouth and tongue. Additionally, the eyes may also become watery or bloodshot, and the skin may sometimes become moist and scaly, particularly around the scrotum in men; and the labia majora, in women. There is also a decrease in the red blood cell count. A deficiency in vitamin B2 in children also results in reduced growth rates.
