Not all Milligrams are Created Equal: The Iron Bioavailability Gap
NOT ALL MILLIGRAMS ARE CREATED EQUAL: THE IRON BIOAVAILABILITY GAP
Iron deficiency remains prevalent worldwide, including here in the US, despite widespread fortification, supplementation, and availability of iron-rich foods. Traditional dietary counseling often focuses on total iron intake; however, iron status is determined by bioavailability, not consumption alone. This session introduces the Iron Bioavailability Gap™ framework to help practitioners understand how physiological regulation, food matrix effects, inflammation, and timing influence absorbed iron. Participants will leave with practical strategies to assess and narrow the gap between iron intake and absorption in clinical practice.
Upon successful completion of this one-hour course, the participant should be able to:
  • Explain why adequate iron intake does not guarantee adequate iron status.


  • Define Iron Bioavailability Gap.


  • Identify dietary and lifestyle factors that meaningfully affect iron bioavailability.


  • Apply practical, bioavailability-informed strategies to close the gap and improve iron status in different patient/client populations.
