My serum iron was a bit elevated during my last bloodwork and I dediced to try some IP6 (1000mg a day on VERY empty stomach with a full glass of water). After a little over 1 month my serum iron dropped by half. If I still had high HCT issues I would definitely try IP6. As an iron chelator in theory it could eliminate or reduce the need for blood donation. The brand I used was Jarrow.
