Hello all - has anyone else discovered that low iron can give lots of symptoms similar to anxiety? Doc did a blood test and discovered I am borderline anaemic so am now on iron tabs. I think I may have been for many years which could have given lots of the symptoms which were always put down to anxiety - light-headed, palpitations, low energy, general anxiety. I even found a mention that low iron levels can affect the levels of serotonin in the brain. Wonder how many people are on anti-depressants who should be on iron tabs? It's early days but I am not getting as many horrid symptoms as a couple of months ago.
