Yeah, parasites can cause the problem as well as a dirty colon where you got too much bad calcium circulating in the blood and not enough good calcium going to the bones and teeth. Lyme disease that attacks the bones will do it. One popular herbalist on CZ maintains this is what happens. Take it or leave it for information.
You do NOT need tap water minerals as they will not help you at all. The body can't use them. Only ionic, plant processed minerals will help. Drink distilled water for the rest of your life, too, as that will help to clan out the blood and arteries of junk minerals.
You can follow my posts on other forums on the subject and get some good information. Hope it helps you. There are some good people on CZ who can help, so just do it! Lol!
