[|Human|] Sir, I am a male aged 44 years. I am a regular blood donor. Today when I went to donate blood I was diagnosed that my HB level is 11.9.I was advised iron supplements.  Which medicine I should take to have normal HB value. Further is it also necessary for me to take calcium supplements as I am already more than 40 years old.Thanks
[|AI|]  Hello, thanks for using Chat Doctor. An HE of 11.9 is not that alarming nor bad though its at borderline of the lowest limit in normal range. It is important to know why the He is going down. You say you are a blood donor and if Thais the reason why your He went down then not a big deal.However, other possible causes of reduced He could be poor nutritional supply of Iron and vitamin B12 which are needed for Red blood cell formation. Calcium is not required in the synthesis of red blood cells, however it's an important element in the body and helps in blood clotting. Iron supplement of an average of 50 mg per day for a month would do you good together with vitamin b12. Hope this helps you.  Chat Doctor.
