Approximately 95% of riboflavin from food is bioavailable, but this absorption is limited to about 27 mg per meal due to a saturable transport system in the small intestine. Understanding this limitation is key to maximizing your intake of this essential vitamin.

Over 90% of dietary vitamin B2 (riboflavin) is initially present in complex coenzyme forms, requiring digestion before absorption can begin. This essential process primarily occurs within the gastrointestinal tract, with the absorption of vitamin B2 concentrated in a specific region of the small intestine.

According to the National Institutes of Health, over 90% of dietary vitamin B2 (riboflavin) is absorbed in the small intestine when ingested as part of a meal. Understanding how is B2 best absorbed can significantly boost your energy production, support cellular health, and improve overall wellness.

Over 90% of dietary riboflavin is present as the coenzymes FAD or FMN, which the body must convert to free riboflavin for absorption. This guide explores the best form of riboflavin to take, comparing the standard form with its more readily usable counterpart for enhanced efficacy.
