💊 Amino acids · Limited evidence
GABA
Calming amino acid taken for stress and sleep. People take it for:
- Stress relief (limited evidence)
- Sleep support (very limited evidence)
- A form of the brain's main calming messenger
Why it works
People take it for stress relief and better sleep, since GABA is the main calming signal in the brain. A systematic review of placebo-controlled trials found limited evidence for stress and very limited evidence for sleep, so results are mixed.
