there is a scientific reason why it works but I dont remember what it is.
You have to take the two together. I think it is the vitamin A that helps but you need Zinc to help it. Been awhile since I figured this out
However since your problem is so bad that you have to have tubes replaced it might not help you.
the Vit A and zinc make copper bio available, which makes iron usable. Check out The Root Protocol. Pretty simple and really effective.
Dosage?
