I looked into one of the references...they put 120mg/L in mice and found it to be bad. Drinking water has about 0.7 mg/L. This is a factor of nearly 200x on concentration and another lot on body mass. Shoot, if I drink 200x more water that will cause problems too!

Concentrations matter.

Appears as though my original comment was flagged. That's OK if the article wasn't well cited.

If you do a Fluoride search here on ycombinator you will find many article that point to fluoride as a nuerotoxin.

Cheers.
