RO unit question/advice

I have a 5 stage RO unit with a DI. I use the water not only in my saltwater tank but for making my son's bottles. What i need to know is if my RO unit filters out the flouride? Or advice on where to find this out. He's at the age now where he needs flouride so if it's being filtered out, i need to supplement. Any help would be greatly appreciated!!
 
I thought this was interesting and wanted a second opinion , as mine is sometime faulty and I have been known to be wrong about a thing or two a time or two. So after talking to a chemist friend of mine.. this friend of mine makes his living off of RO units on a major scale so his word I think is as good as you can get on the subject.

This is what we came up with....

The RO will reject the flouride because the RO membrane is negatively charged and since flouride is negatively charged it would be rejected and sent off through the waste. So Fluoride will not be provided in that water. IMO

Usually I would suggest against anyone consuming Ro/DI water over any length of time simply because if the unit does what it is intended there will be nothing of any substance left in the water good or beneficial. With that said , the formula will more than likely provide the calcium and magnesium needed to balance things out.
