The evidence in words
How much to take
100–300 mg if trialing, evening.
Timing & separation
There are no strict timing conflicts on record for GABA (Supplement); consistency matters more than the exact hour for most goals.
Why the dose is what it is
GABA is the main inhibitory neurotransmitter, but supplemental GABA's central effects are limited by poor brain entry; any effect may be via the enteric nervous system.
Bottom line
The mechanism argues against it and the evidence is thin. Theanine or glycine are better-supported calm/sleep options.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
