This could mean toxicity for glutamate sensitive person who has already sufficient amounts of glutamate.
I don´t try to prove you wrong hv but just giving alternative information.
"Astrocytes are the cells that in the CNS where ammonia is metabolized in a reaction of glutamine synthesis from glutamate and ammonia, and are the primary victim of ammonia toxicity. Bioenergetic failure, oxidative or nitrosative stress and excessive accumulation of glutamine are the interrelated aspects of ammonia-induced astrocytic impairment that contribute to cerebral edema – a major cause of death associated with acute HE."
I will report my first experience with lacutlose soon. Increased energy and getting pleasure from everyday doings but might be from placebo.
