Glycine can be either stimulatory, or sedating. That is, if in glutamate mode, it'll amplify that excitatory state. If in GABA mode, it'll act more like a sedative. It can also be stimulatory due to GABA opposing serotonin, allowing acetylcholine and dopamine to go up. Eventually, GABA also opposes acetylcholine and everything else.
I see, that's interesting. I basically got both the stimulatory and sedative effects from it within a 24 hour period. supplementing GABA itself does not work, right? Apparently it is poorly absorbed in the intestine?
So lets say one wants to implement glycine or magnesium glycinate. Are you saying there is a waiting period where things may be rough for the first couple weeks or so of use, after that there's no issues supplementing glycine? Do you want GABA opposing acetylcholine and everything else. And in that case being a sedative would glycine only be suitable for use before bed
