so how much is too much?
“ so how much is too much?”
If your cup overflow, then you know you’re on to something good.
It seems to me having more than you need is too much. Every molecule of excess iron increases free radical damage.
For example, ferritin less than 70 ng/ml is iron deficiency. People who have ferritin of 140 ng/ml have higher triglycerides than those who have about 70 ng/ml.
Ferritin is a measure of iron stores. If people in the latter group make just two blood donations, their ferritin gets very close to 70 ng/ml.
