iron deficiency anemia
"Technically this helped my anemia - got me from ferritin levels of about 5 to 15 in three months. Apparently it should have been much more though, so not sure what I did wrong. 

Anyway, it did help most of my bad anemia symptoms - heart palpitations, restless leg, tiredness when just walking to the shops. Downside is that it tends to mess up my digestion - unlike other people here who said it constipates them, it gives me a diarrhoea, especially when I drink it with juice."
