💊 What it does
Valerian (Valeriana officinalis) root has been used as a sleep remedy for over 2,000 years. Its active compounds (valerenic acid, isovaleric acid, and various flavonoids) act on GABA receptors — the same target as benzodiazepine medications, but more gently and without the dependency risk. Clinical evidence for sleep improvement is moderate — some trials show significant benefit for sleep latency and quality, while others show no effect, likely due to differences in extract standardisation and study design. It works best for anxiety-related sleep difficulties.
👤 Who needs it
People with difficulty falling asleep, particularly when related to anxiety or racing thoughts. Those wanting a non-habit-forming alternative to sleep medications. Those who have tried other sleep supplements without success.
🥦 Food sources first
Valerian is not found in food. It is an exclusively medicinal herb whose root has the characteristic unpleasant sulphur-like smell. Valerian tea is available but the taste is challenging for most people — capsules are preferable.
🗓 When to supplement
For difficulty falling asleep when anxiety or restlessness is a factor. As part of a sleep hygiene protocol. Consistent use over 2-4 weeks may be needed before effects are apparent — unlike sleeping tablets, it does not work immediately for most people.
🏷 Best form to look for
Standardised to valerenic acid content (0.8-1%). Aqueous or hydroethanolic extract. Combining with lemon balm is traditional and supported by some evidence. Standardisation matters — unstandardised valerian products are highly variable.
⏰ When to take it
30-60 minutes before bed. Takes 2-4 weeks of consistent use to show full effects. Do not expect immediate knockout effects.
