Gamma-aminobutyric acid, or GABA, is a neurotransmitter that plays a role in calming the nervous system, which is important for sleep. Determining an appropriate amount of supplemental GABA to take for sleep is a common question, as dosages used in studies vary. This article explores the range of dosages used in research, outlines important safety considerations, and discusses potential side effects.

However, while some users may notice initial benefits almost immediately, the more significant improvements in overall sleep quality and next-day alertness often become apparent after consistent nightly use over the first week.
