Valerian root extract

Valerian Root Benefits: Sleep, Relaxation & Stress Support

What it is
Valerian root is an herbal extract derived from the roots of Valeriana officinalis, a plant traditionally used in European herbal medicine for relaxation and sleep support. It contains several bioactive compounds, including valerenic acids, iridoids, and volatile oils, which are believed to contribute to its calming effects [1].

Valerian has been used for centuries as a natural remedy for restlessness, nervous tension, and sleep disturbances, and remains one of the most commonly used botanical ingredients for sleep support.

How it works in the body
Valerian appears to influence the GABA (gamma-aminobutyric acid) system, the primary inhibitory neurotransmitter pathway in the brain. Compounds such as valerenic acid may help increase GABA availability or modulate its receptors, promoting relaxation and reducing neuronal excitability [2].

This mechanism helps explain valerian’s effects on sleep onset and perceived sleep quality, particularly in individuals experiencing mild sleep disturbances.

Valerian may also interact with other neurotransmitter systems involved in mood and stress regulation, including serotonin and adenosine pathways, though these effects are less well defined [3].

Clinical research suggests that valerian may help reduce the time required to fall asleep and improve subjective sleep quality, although results across studies are mixed, likely due to differences in extract standardization and study design [4].
