I’m 18 years and feels that I have some low hemoglobin problem. I don’t have taken any appointment with doctor but feel exhausted every time. When I wake in the morning, my eyes look puffy and you can see green vein lines on my temples. It seems that the iron deficiency is inherited as my mom also takes iron supplement pills. I have seen ferrous gluconate on the tablet packaging. Can you tell me about ferrous gloconate?
