Often patients express worry that their ferritin levels are too low, when, in fact, I am concerned about the opposite.
Ferritin is a large protein molecule, and while its role is complex and still unclear, ferritin is generally considered a surrogate marker for total iron storage in the body and often acts as a biomarker of health. Optimal ferritin levels and reference ranges are not currently well defined, but what are considered “normal levels” may actually be too high, and some researchers are advocating for a change in what is considered normal. While we still don’t know the “optimal” numbers, aiming for below the 50 percentile is most likely healthier (20-40 for women, 50-70 for men). Ferritin specialist William R. Ware, PhD, suggests that we should aim even lower for some patient populations (those with cardiometabolic disease, non-alcoholic fatty liver, etc.).
