GABA 4 is a unique formula containing GABA and L-Tryptophan to support the inhibitory (calming) neurotransmitters serotonin and GABA, promoting emotional well-being and restful sleep.

GABA is an amino acid that is helpful for sleep, anxiety and restlessness. For this particular formula it has been combined with the essential amino acid l-tryptophan. Tryptophan breaks down into 5HTP to help manufacture serotonin along with additional cofactors. Research indicates that l-tryptophan supplementation may support emotional well-being and restful sleep. l-Tryptophan also supports healthy sleep quality, onset and duration.
