I can't get my ferritin above 49. My TSH is optimal but havnt been tested for ages for T4/t3, etc. I have a Viridean Balanced Iron complex which provides 15mg of bisglyycinate Iron along with 100mg of but c, 100ug of folic acid and 50 ug of b12. I also take a good multi with selenium, 400 of folic acid, good levels of B vits etc. I am just taking one of my iron pills a day. Can I take more?
