This could be another reason why too much iron in the blood is bad and why many probably don’t need a daily vitamin pill with added iron.
My mother-in-law has that problem. She donates blood every month just to keep down the iron...................
If you eat chocolste or meat, I suggest you donate blood once every two years. I think that’s unlikely to cause a deficiency.
If you get a blood test for iron stores, you will know more precisely how much you can reduce iron without causing a deficiency.
Groups at higher risk of getting severe covid have higher amount of iron stores.
