Valerian Extract

Also known as: Valeriana officinalis, valerian root extract, valerian, common valerian, Valerian Extract

Overview

Valerian root extract is derived from the root and rhizome of *Valeriana officinalis*, a perennial flowering plant native to Europe, Asia, and North America. It has a rich history in traditional medicine, particularly noted for its ability to improve sleep quality and alleviate anxiety symptoms. The bioactive compounds, such as valerenic acid and valepotriates, are believed to be responsible for its sedative effects. Available in several forms including standardized extracts, capsules, and herbal teas, valerian extract provides flexible options for consumers. Research suggests that valerian root can positively influence sleep patterns and reduce anxiety levels, although the quality of studies varies, which complicates definitive conclusions. Nonetheless, valerian remains a well-recognized natural remedy within herbal therapies for sleep disturbances and anxiety management.

Benefits

Valerian root extract has robust evidence supporting its role in enhancing sleep quality, particularly for individuals with insomnia. Systematic reviews propose a relative risk of 1.8 (95% CI 1.2-2.9) for favorable sleep outcomes, with meta-analyses highlighting notable subjective improvements in sleep quality. It is also effective in alleviating anxiety, especially in individuals suffering from sleep disorders. Although some studies indicate modest effect sizes and variability among individuals, valerian extract is particularly beneficial for those struggling to maintain restful sleep and mitigate anxiety, contingent upon the quality and consistency of the valerian extract used in studies.

How it works

The sedative properties of valerian root are largely attributed to its active components, particularly valerenic acid and valepotriates. These compounds enhance GABAergic activity by interacting with GABA receptors in the brain, promoting relaxation and facilitating sleep onset. Additionally, valerian's compounds influence neurotransmitter functions vital for sleep regulation, effectively reducing anxiety and fostering restful sleep.

Side effects

Valerian root extract is generally well-tolerated; however, mild drowsiness or sedation is reported in over 5% of users, particularly at higher doses. Gastrointestinal disturbances and dizziness have been observed in 1-5% of the population, while severe side effects are rare. Caution is warranted when combining valerian with alcohol, benzodiazepines, or other sedative herbs due to the potential for compounded sedative effects. While no significant contraindications are noted, consultation with healthcare professionals is advised for pregnant or breastfeeding women given the limited safety data. Overall, valerian is considered safe for the majority, but users should be mindful of potential drug interactions and personal sensitivity.

Dosage

The typical recommended dosage of valerian root extract ranges from 300 mg to 600 mg per day, with optimal effects usually observed between 400 mg and 900 mg. For sleep enhancement, it is best ingested 30-60 minutes before bedtime. Though no established upper limit exists, dosages exceeding 900 mg may elevate the risk for side effects, particularly excessive drowsiness. Absorption and bioavailability can vary by preparation method, with ethanol extracts often preferred for their enhanced effectiveness.
