Valerian extract is known for its calming properties, making it a popular choice to promote better sleep and alleviate insomnia. The science behind valerian's sleep-inducing effects lies in its ability to increase the brain's levels of gamma-aminobutyric acid (GABA), a neurotransmitter that helps reduce anxiety and promote relaxation, ultimately improving sleep quality. Valerian extract contains valerinic acids (%0,3, %0,45 ve %0,8) and sesquiterpenes.
