The trick is to stay on MSM it is a life time deal for good health. So have you tried the olive leaf ext.? The book of Olive Leaf Ext says it kills Protozoa's.. We slowly worked our way up to 10 tablets a day. And we are still taking that much and will continue to take that much.
Olive Leaf Extract
A New/Old Healing Bonanza for Mankind
by James R. Privitera, M.D.
Please get the book you won't be sorry.. they actually have two out there on Amazon. And they are not that spendy.
I feel it is another life time deal. You know natural things are not like chemical pills. Everyone gets so use to the Quick Fix that really fixes nothing.. just mask the problem. You Nutrition for a life time. From what I have read. It takes 7 years to replace every Hair on your head. and that long to repair some parts of the body.. some do it in shorter times..but, there are some that take 7 years. So the deal is to be consistant with what you take to repair the body and to protect it.
