Dr. Hulda Clark seemed to think that most parasites fed on iron but I have my doubts about her advice to NOT take iron.
I haven't been taking iron because she says not to. When I read your post I thought, "Hmmm that is an interesting point". So I dug out my iron and took one. Got a physical "buzz" from it.
I think she discovered the parasites were subdued by a lack of iron. I also think that it is probably not good for anyone to avoid iron. Only a healthy body can fight parasites.
So what I am saying is "Yes" I think there is a connection but I am not sure what it is. It seems to have helped you. I am going to keep taking it and see what happens. Maybe my muscle spasms will go away. Thanks for posting the question.
