Buying tips

When choosing a vitamin B2 supplement, consider whether you prefer the standard riboflavin or the active form (riboflavin-5-phosphate) for better absorption. Check for vegetarian/vegan labels, allergens, and third-party testing. Most supplements offer 100 mg per serving, but lower doses are available. Price varies by brand and form; active forms tend to cost more.
