Short answer: GABA is the brain's primary inhibitory neurotransmitter, helping reduce nervous system hyperactivity, while L-Theanine promotes relaxed alertness by supporting alpha brain wave activity, without sedation.
Why these two ingredients address genuinely different parts of calm
GABA's role centers on directly reducing hyperactivity, while L-Theanine's role centers on maintaining alertness alongside relaxation — two complementary, not overlapping, mechanisms.
Why "without sedation" is a specific, meaningful distinction for L-Theanine
This directly addresses a common concern about calming supplements causing drowsiness — L-Theanine's specific mechanism supports calm focus rather than sleepiness.
💡 Worth knowing: these two ingredients form the formula's first of three stated pathways — neurotransmitter balance.
