Vitamin B2 plays an important role is a number of bodily processes including energy production, cell growth, and metabolism. The body can only store small amounts of vitamin B2 so a daily diet that includes foods containing B2 is essential to good health. A number of common foods such as eggs, milk, green vegetables, beef, pork, whole grains, and avocados are high in B2. Deficiency can cause symptoms such as chapped lips, skin rash, sore tongue, hair loss, sore throat, and red itchy eyes. A B2 deficiency during pregnancy can increase the likelihood of certain birth defects.
Testing for vitamin B2 is often ordered for people who are suspected of being malnourished, especially if they have common symptoms of B2 deficiency. For additional testing options, please see our Vitamin Testing Category.
