Chemical Forms

Recommended

Valerian root extract standardized to valerenic acids
Valerian root powder
Valerian root tincture

Avoid

Unstandardized dried root capsules (valerenic acid content unknown)
Multi-herb 'sleep' blends with undisclosed valerian doses

Expert Note

Standardized extracts typically provide 0.3-0.8% valerenic acids, the most studied active constituents. Tinctures and teas vary widely in potency. Unstandardized powders may contain minimal active sesquiterpenes and have inconsistent clinical support compared to standardized extracts.

Protocol

Amount

300-600 mg

Frequency

Once daily, 30-60 minutes before bed

When

Evening, 30-60 minutes before bedtime. May be taken with a small snack to reduce stomach upset.

Condition-Based Dosing

Mild insomnia or sleep latency > 30 min

400-600 mg standardized extract nightly for 4 weeks— If no improvement after 4 weeks, discontinue.

Mild situational anxiety with sleep disturbance

300-500 mg standardized extract, evening or divided doses— Lower doses are often sufficient for daytime anxiety without excess sedation.

Safety & Limits

Upper Safe Limit

900 mg/day of standardized extract (practical ceiling based on clinical trials; no official UL established)

Cycling

Safe for continuous use

Contraindications

Pregnancy or breastfeeding — insufficient safety data, avoid unless supervised

Surgery scheduled within 2 weeks — potential interaction with anesthetics/sedatives

Severe liver disease — rare case reports of hepatotoxicity; avoid

Epilepsy or seizure disorders — theoretical concern due to GABA modulation; insufficient safety data

Synergies

Melatonin

Melatonin regulates circadian timing while valerian promotes GABA-mediated relaxation, potentially improving sleep onset and quality through complementary mechanisms.

Magnesium glycinate

Magnesium supports GABA activity and muscle relaxation, which may enhance valerian's sedative effects.

L-theanine

L-theanine increases alpha brain waves and GABA; paired with valerian it may deepen relaxation without next-day grogginess.

Avoid Combining With

✕Alcohol (additive CNS depression — avoid concurrent use)
✕Prescription sedatives including benzodiazepines and sleep aids (additive effects — medical supervision required)
✕Caffeine in late afternoon/evening (reduces perceived sleep benefit)
