Are you still having issues with
high hematocrit? I am on telmisartan and at some point was taking grapefruit extract and I didn’t notice any negative interaction. Grapefruit extract seemed to help a bit my hematocrit but what was a game changer for me was a dosage reduction. I am experimenting with IP6 but haven’t tested my HCT since i started. However my serum iron dropped quite a bit since i started and my chest is not as red as before during workout etc. For me skin (specially in the chest area) is highly correlated with my HCT.
