Valerian root — the active wind-down botanical
Valerian has been the wind-down herb of choice in Europe for over a thousand years. It’s the only botanical in phew’s formula with measurable GABAergic activity — meaning it works on the same neurotransmitter system some prescription anti-anxiety medications target, more gently. We use a 0.8% standardized extract, not chopped root.
What valerian actually does. Valerenic acids — the active compounds — bind to GABA-A receptors and inhibit GABA reuptake, slowing the wired part of the brain. The effect is mild and stacks with the body’s own relaxation pathway rather than overriding it. Traditional Western herbalism has used valerian as a sleep aid since at least the 11th century.
Why standardization matters. Most valerian products use ground root powder — which contains valerenic acids in whatever concentration the harvest happened to produce. A 0.8% standardized extract guarantees a consistent dose of the active compound every batch. Without standardization, you can’t reproduce an effect from tin to tin.
How much we use. 50 mg of 0.8% valerenic acid extract per strip. That’s a low-clinical dose — enough to be felt as a settling cue, not enough to make you groggy. We chose the dose to support the melatonin signal, not replace it.
Per-batch transparency. Valerian is one of the actives we’re working hardest to get supplier transparency on, because the gap between “chopped root” and “standardized extract” is where most of the supplement industry hides. Email hello@tryphew.com for the current batch source.
