Research has shown that riboflavin deficiency can alter iron absorption and cause anemia , which leads to fatigue. Riboflavin is involved in red blood…
Folic acid is important, too, as someone said earlier.
What is folate-deficiency anemia? Folate-deficiency anemia is the lack of folic acid in the blood . Folic acid is a B vitamin that helps your body make red blood cells. If you don’t have enough red blood cells, you have anemia.
I have to remember this because I just quit dairy and I that can be a good source of riboflavin.
See how beef can leave you short on some vitamins, and then if you have a negative genetic predisposition, it can be difficult to overcome without some supplemental vitamins.
Do you take a B complex, Robin?
 
      
    
 I have been hypothyroid for two years (probably a lot longer but that’s when I was diagnosed) and one of the side effects is low absorption of nutrients including iron. My ferritin was on the floor only a few months ago. I can’t take normal iron, my doctor prescribed me the “creme de la creme” of iron and laxatives and I still couldn’t go. So I did loads of research and got recommended these heme iron tablets.
