Valerian Root
Also known as: Valeriana officinalis, Valerian Extract
The most widely used herbal sleep remedy — evidence supports reduced time to fall asleep and improved sleep quality.
What it is
Valerian (Valeriana officinalis) is a perennial herb native to Europe and Asia whose root has been used as a sedative and sleep aid for over 1,000 years. It is the most widely sold herbal sleep product in Europe and North America. Clinical evidence is mixed but generally supports its use for improving subjective sleep quality and sleep onset latency, particularly in individuals with mild-to-moderate insomnia.
How it works
Valerenic acid (the primary bioactive) modulates GABA-A receptor function — the same receptor target as benzodiazepines, though with much weaker and non-addictive action. Isovaleric acid and valerenic acid also inhibit GABA breakdown. Valerian also contains flavonoids (linarin, hesperidin) that contribute to GABAergic activity. The combination of compounds appears more effective than isolated valerenic acid.
Clinical dose range
300–600 mg extract/day (taken 30–60 minutes before bed)
Most trials use 300–600 mg of standardized extract 30–60 minutes before sleep. Some studies show benefits with multi-week supplementation even without immediate sedation — sleep quality improvements may emerge gradually. Aqueous or ethanolic extract of root is the validated form.
Forms comparison
What to look for on the label
- Specifies valerenic acid percentage (≥0.8% preferred)
- Root extract (not aerial parts or seed)
- Third-party tested for actives and contaminants
- Dose 300–600 mg per serving to enable bedtime dosing

Safety & dosing notes
Very safe with long history of use. Drowsiness next morning at higher doses — start with 300 mg. Rare reports of paradoxical stimulation. Do not combine with other sedatives or alcohol. Avoid driving after use. No evidence of dependence or withdrawal at typical doses.
SuppsBuddy validates valerenic acid standardization and verifies that dosing aligns with the 300–600 mg clinical range. Products without standardization disclosure receive a lower ingredient transparency score.
