I must criticize my previous behavior since I did not verify with blood analyses the actual values of iron in my blood.
However, it turns out they are good, either blood iron concentration and ferritin, which is an index of iron stored in the blood. Too much iron, as discussed, may be harmful.
Still not sure about my iron index. I keep thinking I may need more, since vegetarians are always warned about it. But I find the best practice are the energization is exercises from Paramahansa Yogananda to stay in health. I watch so many people around me with so many health problems and feel so fortunate to have been given these exercises early in life and to have continued practicing them.
