Another thought is that a lot of things when applied to the skin are absorbed differently than by mouth. Filtered in a way. Ray puts his vit A and D on the skin. He says it's a safer way to dose them because of additives if I remember right.
And, the fact that he advises using baking soda and epsom salts through the skin in the bath indicates to me that he isn't worried about the water in the bath. Also, I think most cities in the US are fluoridated, and, still he recommends the bath. When he thinks something (meat for example) is better in Mexico, he says he eats more meat there. But he hasn't said he takes more soaks there because of our fluoride. But, is his water in Mexico fluoridated too. Does he take the baths himself anyway?
