Vitamin B2 - Riboflavin

Vitamin B2 (also known as Riboflavin) is another water soluble vitamin. It is necessary to help your body release energy from food (from protein, fat, and carbohydrates). Riboflavin is also important for the maintenance of healthy hair, skin, and nails, and for good vision (prevention of cataracts).

It can be found in lean beef, pork, poultry, fish, seafood, liver, legumes, eggs, cheese, milk, dairy products, green leafy vegetables, nuts, and enriched/fortified whole grain products. Riboflavin is the only B vitamin found in dairy products. It can be easily destroyed by light which is why milk cartons and jugs are opaque.

The recommendation for men (age 14 - 70+) is 1.3 mg/day, for women (age 19 - 70+) it is 1.1 mg/day with an increase to 1.4 mg/day during pregnancy and 1.6 mg/day during lactation. Females age 9 - 13 have a RDA of 0.9 mg/day, while females age 14 - 19 have an RDA of 1.0 mg/day. Recommendations for children are lower at 0.5 mg/day for 1 - 3 years old and 0.6 mg/day for 4 - 8 years old. Deficiency symptoms include itchy sensitive eyes, eczema, mouth ulcers, cold sores, cracked lips, and hair loss.
