Some thought is that iron "feeds" the viruses we may have ie; EBV, CMV etc.
On the other hand, we can feel like real crud if our iron and iron stores are very low.
Read into BlackStrap Molasses.
I could not get my iron stores up to save my soul, no matter what I did. I have now been taking the BlackStrap for over 2 months and I feel a HUGE difference in my energy as well as my bruising is not near as bad. I take 2 TBSP daily.
I just had my iron and stores (all that good stuff) re-tested and will find out the results Nov. 2nd.
