Since reverse osmosis and distillation remove the minerals as well, is there any really efficient way (such as a good  all-around mineral supplement) a person can take?  I know growing your own food helps, but not everyone can do that.  I have to take extra magnesium to prevent my muscles from stiffening, high blood pressure, etc.  I developed severe muscle cramping in my back & thighs  due to, I believe, previous injuries.  It was not until I read a doctor's recommendations to take as much magnesium as calcium in supplements that I overcame the cramping, etc and brittle bones I developed. I know a lot of commercial food does not have the proper mineralization - the land has been depleted, one way or another (as in commercial fertilizers locking up much of the minor minerals in the soil).

For what it's worth, here is my experience-
I used fluoride toothpaste everyday for 30 years and every year when I went to the dentist I had at least one cavity.
Then I started flossing and quit using fluoride toothpaste. Guess what? I have not had a cavity in over 10 years.
My dentist even told me, if you only have time to brush or floss, make sure you floss!

Avoid fluoride toothpaste at all costs.  You can get good toothpastes at your health food store or online that have excellent natural anti-bacterial ingredients.  Any supposed benefit of fluoride is far outwide by its consequences.
