Vitamin B2
Vitamin B2, also known as riboflavin, is needed for normal energy metabolism and cell activity. It plays a role in nervous system function and helps maintain healthy skin and vision. Since the body doesn't store large reserves of riboflavin, it's important to get it regularly through food or supplements.

Natural sources of vitamin B2
Riboflavin (vitamin B2) occurs naturally in dairy products, eggs, meat, fish, almonds, mushrooms, and whole grain products. In supplements, it's used either on its own or as part of various B-complex formulas, capsules, tablets, and powder blends.
Recommended vitamin B2 dosage
Riboflavin needs can vary depending on diet, physical activity, and overall health. Adults are generally advised to get around 1.1-1.6 mg of vitamin B2 per day, although some supplements use higher doses. The right amount is best chosen individually, especially if riboflavin is taken alongside other vitamins or over a longer period.
Possible side effects of vitamin B2 and interactions with medications
Riboflavin is generally considered a safe, well-tolerated vitamin, as the body removes any excess through urine. In rare cases, higher doses may cause mild digestive discomfort or turn urine a bright yellow color. Riboflavin can also interact with certain medications, particularly those that affect how vitamin B2 is absorbed or metabolized, so it's worth checking with a doctor before long-term supplement use if you're taking prescription medication.
