Has anyone tried Vorck's protocol for raising ferritin? Mine is around 40 and I feel like after next donation it's gonna be less than 20 and I'll feel like shit.

I got the iron bisglycinate from Kirkman like he recommended but I am a little bit spooked, taking 3 of them (75 mg of iron) 3 times a day seems like a lot and what if instead of building my ferritin it all goes into my hemoglobin and my hematocrit goes into like 60?
