Amusing differences in prescriptions: apparently >30mg of Fe2+ per dose requires prescription in Poland. According to pharmawiki something with 100mg/dose is in category D in Switzerland.
No obvious ones, but perhaps I'm failing at eating enough of it. I did give away half a liter of blood a month ago, but that shouldn't have such effects.
(I have 15ug/l of ferritin, but a month or so ago had completely normal hemoglobin level)

Ah, and it's not B12-related: I have a very reasonable level of it iiuc (1.3nmol/l).
