Zizyphus

Also known as Zizyphus spinosa

Jujubosides and flavonoids in Zizyphus interact with neurotransmitters in the brain, particularly the GABAergic system. GABA (gamma-aminobutyric acid) is the primary inhibitory neurotransmitter in the brain, supporting relaxation. Scientifically studied to show it can reduce the time it takes to fall asleep and increase overall sleep duration, improving sleep quality.
