Official title: Dietary iron requirements in US adults
Funded at Lsu Pennington Biomedical Research Ctr · NIH-11361650 · Data updated 2026-11-12
A large, diverse group of US adults will help scientists pinpoint how much iron they need and how well different everyday diets supply iron.

Who could benefit from this research
✓Could help
Adults 21 years and older who are enrolled in the All of Us Research Program and willing to participate in diet and biomarker assessments.
✕Less likely to help
Individuals not enrolled in All of Us or those not meeting eligibility criteria may not directly benefit.
What this research studies
This project adds a supplemental study to a national research program to measure iron requirements in adults across the United States. Researchers will recruit about 300 participants from the All of Us program and track iron losses and how well iron from three common mixed diets is absorbed. They will also collect iron-status indicators to update current recommendations. The goal is to create more accurate iron guidelines that reflect real diversity in the US population and real-world eating patterns.
Why it matters
Potential benefit: Better, more personalized iron guidelines could prevent iron deficiency or excess in diverse groups of US adults.
How similar studies have gone: Prior work has informed iron recommendations, but this study aims to refresh them using a large, diverse US sample.
