If I am taking ferrous sulfate to keep ferritin up, will that raise hemoglobin?

AlphaMD's Answer

Think of ferritin as a stack of bricks used to build a building. In this analogy, the building is your hematocrit.

Just because you have more bricks, doesn’t mean you have to build a taller building. The extra ferritin that is not used is excreted from the body. The bricks are retuned to the factory.

Testosterone increases bone marrow production, but only up to a set point. It is not exponential. There is an upper limit.
