Vitamin B2 (Riboflavin): Food Sources, Daily Value, Deficiency Context, and Supplement Labels
Vitamin B2, or riboflavin, is a water-soluble B vitamin involved in normal energy metabolism and other enzyme systems. It is found naturally in foods and is also added to some fortified foods and supplements.
Editorial context: This page is general riboflavin education and is not a current Nutribota product page. See Research & Editorial Standards.
Food Sources
Riboflavin can be found in dairy foods, eggs, meats, some fish, almonds, mushrooms, green vegetables, and fortified grain products. Actual intake depends on food choices and portion sizes.
Fortified Foods
Some grain and cereal products contain added riboflavin. Check the Nutrition Facts label rather than assuming every bread, cereal, or pasta product is fortified identically.
How It Appears on Supplement Labels
Vitamin B2 may appear as riboflavin or in other labeled forms depending on the product. The Supplement Facts panel shows the amount per serving and usually provides a percent Daily Value when applicable.
Water-Soluble Does Not Mean Unlimited
Water-soluble vitamins are handled differently from fat-soluble vitamins, but the category should not be interpreted as “any amount is harmless.” Use the labeled serving and consider total intake from multiple products.
Deficiency Context
Riboflavin deficiency is uncommon in some well-nourished populations but can occur in specific dietary or medical circumstances. Symptoms are not specific enough for self-diagnosis from an article.
Who May Need Individual Guidance?
People with restrictive diets, malabsorption, significant medical conditions, pregnancy-related nutrition questions, or multiple supplement use may benefit from individualized guidance from a qualified healthcare professional.

Bottom Line
Riboflavin is best understood as part of overall dietary intake rather than as a stand-alone “energy” shortcut. Use current labels and product-specific directions when evaluating a supplement.
