I'm just starting on Aceytl l-Carnitine right now. 1000mg per day. This is a powder. I'm taking it on an empty stomach first thing. No stomach upsets yet, but my teeth a a little "squeaky" and dry afterwards. Does this stuff harm teeth? Also, to get the out out of Alcar, should I take it with Alpha Lipoic acid? Or Alpha GPC, or Citicoline? Any supplement recommended? There are supplements that have 1600mg of Alpha lipoic acid/Aclar in one capsule... Any comments on this?
