Each person here reading can make their own decisions on the Taurine.

You know, I recall way in the past, it was used by the Tourette's community (and ADHD too).

We always have it here, because of our cats. Vets often recommend additional taurine if cats get human food treats.

I only use it for my gall bladder (I have had 4 tests showing no stones over the years and including most recently). A low dose helps me prevent painful attacks. But that action is different from the neurological actions it has on membrane stability. The nerve impulses travel along the nerve membranes, using the electrolytes mentioned in the wiki article.
In fact there is a supplement, magnesium taurate that I recall Tourette's patients used.

While the mag content of this is pretty low per tablet, the combo makes good sense if used in the proper dosages.
