So I guess my serumiron was normal (almost in the middle of the range) because I had skipped the supplement only the day prior to the test.
I'm far from reaching 200 with my Ferritin, so, as I understand, iron overload is unrealistic for me, at least for the coming few years. My Ferritin was 9,5 when I had the test in early July; thinking to have another one in September.
