Good Lord. So your relation only discovered her iron deficiency in the last few years? I am the same but iron deficiency is something both my mother and at times my sister have had. But its unsure whether or not iron deficiency is hereditary. General consensus with Nurses at work was it isn’t hereditary.I’m not sure if fatigue /iron deficiency are related symptoms to mRNA or Vector shots, could be, dunno.
my grandmother in law is suffering from a similar symptom regarding iron deficient blood. The standard dietary supplements are making her nauseous so we now have her on this which seems to do the trick although it is rather expensive.
maybe something worth looking into.
Before Covid times i was a cleaner in a hospital for a year and was often tired then, but put it to the managers working us hard. Cheers
edit: just googled Synthesit. That looks like interesting stuff
