The child's is probably the best, then the teen and then the adult.
The atomic bomb version is ONLY for the radical person that thinks they can't get something hot enough in their mouth. Jody said this morning she needed to bottle up some more atomic bomb formula....I SAID WHAT?????????? She said yep, the people still have the same crazy notion the hotter the better.
NO ONE has any sense at all, if they didn't start out with the child/teen ot adult formula first. To just buy the atomic bomb spray is almot crazy, because it will be too hot for them to get much of any use out of it. They will not be able to consume enough to be a good benefit for the teeth and gums, that is why the "adult" formula was made and the atomic bomb just a"crazy" formula for crazy people. I would think a 2 oz bottle of atomic bomb formula would last anyone many years. Unless your going to spray it in the air, etc., etc. and not be using it in the mouth.
It almost never fails, people on the internet, just naturally go for the "strongest" thinking they are getting the "best", which is rarely ever the case. The "BEST" is what you can and want to take enough of, so in fact, for most people that means the "baby" formulas. The mildest best tasteing.
