GABA and Quieting the Mind

Written by the Yu Sleep Wellness Desk · Updated September 2026
Quick answer: GABA (gamma-aminobutyric acid) is the brain's primary inhibitory neurotransmitter, associated with quieting mental chatter and physical tension that can prevent sleep onset. Yu Sleep contains 100mg per serving.

What is GABA?

GABA is a neurotransmitter the brain produces naturally to calm neural activity. It's often described as the brain's "off switch," counterbalancing excitatory signals that keep the mind active.

Why supplement with GABA?

A racing mind at bedtime is one of the most common barriers to falling asleep. Supplemental GABA is associated with helping quiet that mental chatter and ease physical tension.

What does the research say?

Research on oral GABA supplementation and its effects on relaxation is an active area of study. General background is available via the NIH Office of Dietary Supplements.

GABA's role in Yu Sleep

At 100mg, GABA works alongside L-theanine as part of the fast-acting calming component of the Yu Sleep formula. See the full ingredients breakdown.

Safety considerations

GABA is generally well tolerated. The supplement's GABA-enhancing properties may amplify the effects of other CNS-depressant medications — consult a doctor if you take sedatives or similar medication.
