At Christmas I was turned away from giving blood as my haemaglobin was 124. I have been getting annual medicals via my work place and my last 5 haemaglobin results were 141, 137, 127, 128, 125 so something happened to my haemaglobin a few years ago and it has never recovered. I have been falling asleep almost every evening for an hour or two but thought it was just a feature of getting older as I am mid 50s.
i started taking a multivitamin for over 50s with 100% daily iron requirement and just took another test to see the impact of three months of that. My haemaglobin has dropped another point to 123. I got a lot of blood markers checked and some other results which may be linked to energy are:
Iron - 15.3
Ferritin - 75
vit D - 56 (my supplement has 20ug which is 400% of daily needs)
Vit B12 - 54 (my supplement has 10ug which is 400% of daily needs)
Folate - 25
Is it possible I was deficient in B12 until I started the supplement and that has been affecting my haemaglobin? I have read a little about pernicious anaemia.
One other marker which is borderline low is my haematocrit which is the volume my red blood cells take up. This is also linked to anaemia and vit b12 deficiency.
