A complete guide to ferritin at-home and finger-prick testing options, including normal versus optimal ranges, what low or high ferritin means for hair loss, fatigue, and restless legs, and how to act on your results.
Ferritin test codes, normal ranges by sex, and thresholds: under 30 ng/mL signals deficiency, over 500 ng/mL needs workup for overload or disease.
A guide to ferritin target ranges in longevity medicine, covering optimal levels for iron stores, hair loss, restless legs, and cardiovascular risk, with primary-source citations throughout.
A guide to how medications, supplements, and hormone therapies shift ferritin levels, what the optimal range looks like, and how to interpret changes in the context of iron stores, hair loss, and restless legs syndrome.
How diet, fasting, inflammation, and lifestyle choices raise or lower ferritin, and what the optimal range looks like for iron stores, hair loss, restless legs, and longevity medicine.
How training affects iron stores, how to interpret ferritin with other iron tests, and what evidence supports diet, oral iron, IV treatment and monitoring.
Medications that raise ferritin include oral and IV iron, methotrexate, estrogen-containing contraceptives, niacin, tamoxifen, amiodarone and alcohol use.
A guide to raising or lowering ferritin using diet, supplementation, phlebotomy, and lifestyle changes, backed by clinical trials and society guidelines.
Why ferritin reference ranges differ by sex, how menstrual cycles and hormones shift iron stores, and what optimal ferritin actually means for hair loss, restless legs, thyroid function, and longevity.
Ferritin reflects your body's iron storage capacity, not circulating iron. Learn what normal ferritin levels mean, causes of high and low results, and evidence-based ways to correct abnormal values.
Learn what your ferritin level means, what counts as normal, and exactly how a high or low result shifts your clinical treatment plan for iron deficiency, hair loss, restless legs, and more.
A clinical guide to the lab tests you should pair with ferritin, including iron panel, CBC, CRP, transferrin saturation, and more, to accurately diagnose iron deficiency, overload, or inflammation.
Normal ferritin runs 12 to 300 ng/mL, but functional optimal is 40 to 200 ng/mL. See target ranges by sex and why symptoms can persist within normal.
18 ng/mL falls below the 30 ng/mL functional deficiency threshold for adult women, even with a normal CBC. See ferritin ranges by age decade.
Normal ferritin is 30 to 300 ug/L in men and 10 to 200 ug/L in women, but context matters. See what low, high, and borderline results actually mean.
