If you struggle with racing thoughts at bedtime, GABA may be what your brain is missing. GABA (gamma-aminobutyric acid) is the most important inhibitory neurotransmitter in the central nervous system — its primary role is reducing neural excitability.
Produced naturally from the amino acid glutamate, GABA inhibits nerve transmission, creating a calming effect. This is the same mechanism targeted by prescription anti-anxiety medications, though GABA supplements work more gently without dependency risks. When GABA is low due to chronic stress, the result is anxiety, restlessness, and insomnia.
Research shows insomnia patients often have GABA levels nearly 30 percent lower than healthy sleepers. This explains the “tired but wired” feeling. Sublingual delivery may improve GABA bioavailability significantly.
L-Theanine enhances GABA activity and promotes alpha brain waves. 5-HTP supports serotonin production for melatonin. This is the approach used by Yu Sleep. See the full ingredient list or order today.
