Silva is right! My doctor discussed this with my sister and I and mentioned that I could donate blood if I wanted to, because my iron levels are in the normal range but that my sister could not donate iron because her iron levels tend to be too low. He offered, (because he knows I love this knowledge) that those whose iron levels tend toward the high side, can simply donate blood to see if that helps them lower than iron counts as that is the best way to handle it. I have read articles where they recommend those who donate blood often to get their iron levels checked to be sure that it is not too low. Also, too much iron, copper, zinc, sugar or process foods have all been linked to causing grey matter to form on the brain, which in turn causes Alzheimers and Dementia. Its worth doing what it takes to get the iron levels to normal.
