Good Dietary Sources of Vitamin B2 (Riboflavin)

Like many of the B vitamins, vitamin B2 can be found in a wide assortment of foods. B vitamins need to be obtained in sufficient amounts daily, so make sure you are getting enough by including a mix of the following foods that are good dietary sources of vitamin B2.

Please note that vitamin B2 remains stable and potent when heated. However, it does leach into water when boiled. Also, riboflavin contained in food can be rendered inert when exposed to light. So, riboflavin-rich foods, ideally, should be stored in containers that are opaque. Avoid using glass or clear plastic containers, as the food will be robbed of vitamin B2’s health benefits.
