How does Riboflavin work?

Riboflavin is required for the proper development and function of the skin, lining of the digestive tract, blood cells, and many other parts of the body.

It can be found in certain foods such as milk, meat, eggs, nuts, enriched flour, and green vegetables. Riboflavin is frequently used in combination with other B vitamins in vitamin B complex products.
