I read LDN helps rid the brain of excess Glutamate. This follows..

"Thus, while the Mayo researchers propose finding ways to block glutamate, the benefits of low dose naltrexone and beta lactam antibiotics lie in their ability to reduce glutamate excess"

I was looking into amino acids to boost growth hormone to heal me quicker from exercises. Glutamine is what's in 1 of the combo pills. The other is L-Ornithine + L-Arginine.

I never found any one that could tell me the difference between Glutamine, Glutamate, Glutamic Acid.
Glutamic Acid = 1 of the 4 Copaxone ingredients.
Glutamate = no good by what I read for us.
Glutamine = ?
