/WHAT_IT_IS
Ferritin is the body's iron storage protein. It's the best single measure of total body iron stores and also an acute-phase reactant.
/NORMAL_RANGE
Reference: 30–400 ng/mL. Optimal: 80–150 for most men.
What does high Ferritin mean?
- +Iron overload (hemochromatosis), inflammation, fatty liver, heavy red meat intake.
What does low Ferritin mean?
- +Iron deficiency.
/ON_TRT
TRT increases red blood cell production, which can deplete iron stores over time even without obvious anemia. Persistently high ferritin on TRT may indicate hemochromatosis — a common reason men feel exhausted despite good T levels, and frequently the actual reason their hematocrit is so high.

FAQ
/01Should I supplement iron on TRT?+
Only if you're deficient. TRT raises hematocrit via erythropoietin, not iron — extra iron without deficiency just adds oxidative stress. Donating blood for high HCT actually helps men with iron overload too.
