Sleep support evidence brief
GABA is an inhibitory neurotransmitter positioned as a calming and sleep supplement. Claims usually focus on relaxation, stress, sleep onset, and sometimes growth hormone.
May influence stress, sleep, or transient growth-hormone markers, but the practical sleep/stress evidence remains limited.
Sleep/stress evidence is limited; transient GH-marker studies should be treated as biomarker findings.
Sleep trials and growth-hormone studies use different forms, doses, and timing; products are not interchangeable.
Growth-hormone marker changes should not be treated as proof of meaningful body-composition or recovery outcomes.

The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
Send the disputed claim, source link, and why it changes the practical verdict. Corrections that materially affect the claim, dose, caveat, or rating are prioritized.
