Nearly One In Three Americans Have Undiagnosed Iron Deficiency, Study Suggests

NBC News (9/24, Carroll) reports, “Nearly 1 in 3 Americans may have an undiagnosed iron deficiency, a problem that can lead to fatigue, brain fog and difficulty concentrating, a new study suggests.” The “analysis of data from more than 8,000 adults in the U.S. revealed that 14% had low iron blood levels, a condition known as absolute iron deficiency, while 15% had the right iron levels but their bodies couldn’t use the essential mineral properly, known as functional iron deficiency.” The findings were published in JAMA Network Open.
