I'm living abroad at the moment and not sure about some advice I received from the doc here. Been having v. heavy periods for the past couple of months and my iron levels are down (Total iron 7.1 umol/L, saturation 13%, ferritin 22 ng/mL). The docs has advised me to take 162mg iron supplements twice a day for 3 months. This sounds rather a lot, does this sound safe, I have no idea?
