A site that has some very interesting findings, based on muscle testing.

" Like the thyroid gland that enlarges when it is searching for Iodine, (forming a goiter) our observation has been that the prostate, too, enlarges when it is searching for what it needs---in this case it is not iodine, but oxytocin---and it is interesting to note that Iodine is one of elements that oxytocin requires."

"Oxytocin synthesis requires iodine, manganese, zinc, and vitamin C. This occurs in the hypothalamus, is sent down and stored in the pituitary gland, and is also synthesized in the prostate. We find that in many cases of prostate enlargement, improving the synthesis of oxytocin has allowed the prostate to resume its correct size. However, the big caveat is that unless the body is freed from a toxic load of MSG, this possible solution will not show any clinical improvement."

"In our clinical practice we have found that Mono-Sodium-Glutamat (Natrium Glutamat) not only creates cognitive loss, asthma and migraine headaches, it also clogs specific pores in the prostate gland so that oxytocin, a hormone from the pituitary, can't access the prostate tissues where it is needed."
