Vitamin B2 is an essential building block for glutathione, a key anti-oxidant. Deficiency symptoms include cracking at the corner of the mouth and on the lips. Diets low in dairy products are especially likely to be deficient.

Good food sources of vitamin B2 are dairy products, green leafy vegetables, fruits, meat and cereals.

Vitamin B2 is also known as riboflavin.
