Buying Guide

Choose the right riboflavin dose

Riboflavin products range from ~100 mg to 400 mg; select a dose aligned with your daily goals and consult a clinician for higher therapeutic doses

Consider formulation and bioavailability

Riboflavin-5'-phosphate (bioactive B2) may be better absorbed for some users compared with standard riboflavin salts

Match form to your preferences

Capsules and tablets suit daily regimen and higher doses, while gummies offer palatability but may have added sweeteners and lower mg-per-serving

Check product tags and extras

Look for features like gluten-free labeling, non-GMO claims, or added cofactors such as CoQ10 if you want targeted metabolic or cellular support

Compare cost per dose and pack size

Value packs and multi-packs reduce per-dose cost for regular use; calculate cost per daily serving when choosing between 100 mg and 400 mg strengths
