Buying Guide

Check the riboflavin dose

Look for standardized milligram amounts per serving to match your target intake and any practitioner recommendations

Choose the right form

Capsules, tablets, and gummies differ in absorption and convenience—capsules and vegetarian capsules often avoid extra sugars or fillers

Verify additional ingredients

Products with added cofactors like magnesium or CoQ10 may support specific uses but can change tolerance and interactions

Consider purity and labeling

Prefer products with clear ingredient lists, non-GMO or gluten-free claims if relevant, and minimal inactive additives

Match supplement to your goal

Select riboflavin for general energy metabolism, migraine support, or eye health depending on the product tags and formulation
