Fall asleep faster
L-Theanine and Valerian Root reduce the time between lying down and falling asleep — the gap that feels endless when your mind won't switch off. Most people notice this within 3–5 days.

What Changes
Three things people notice first
Stay asleep through the night
Night waking is typically caused by cortisol spiking in the early hours. Ashwagandha KSM-66® and Magnesium Glycinate work on the HPA axis to flatten that spike. Most people notice fewer wake-ups by day 7–10.
Wake up restored
Sleep quality — not just hours — is what CLARIA improves. Deeper slow-wave sleep cycles. Waking without the dragged-through-mud feeling. This is the one people describe as the most noticeable change.
The Formula
Six ingredients. Three problems solved.
Most sleep supplements target one thing. Sleep disruption usually has three causes happening at once: elevated cortisol, low GABA activity, and an overactive stress response. CLARIA addresses all three.
Cortisol Regulation
Ashwagandha KSM-66® + Lemon Balm
Ashwagandha KSM-66® is the most researched ashwagandha extract, demonstrated in double-blind trials to reduce serum cortisol. Lemon Balm works synergistically to reduce the anxiety and restlessness that precedes sleep — particularly effective for the "tired but wired" feeling.
GABA Support
Magnesium Glycinate + Valerian Root
Magnesium is essential for GABA production — the calming neurotransmitter that tells your nervous system it's safe to rest. Glycinate is the most bioavailable form. Valerian Root amplifies GABA activity and has been shown in clinical studies to reduce sleep onset time.
Natural Melatonin + Alpha Wave Support
Montmorency Tart Cherry + L-Theanine
Montmorency Cherry is one of the few natural food sources of melatonin and has been shown in clinical research to reduce night waking. L-Theanine promotes alpha brain wave activity — the relaxed, receptive state that makes it possible to let go of the day's thoughts and drift off without sedation.

CLARIA is the first supplement that's actually worked consistently. I fall asleep within 20 minutes and I'm not waking at 3am anymore. Three months in and I'm still sleeping this well.

I was sceptical. Within a week I was sleeping through. My partner noticed before I did — she said I'd stopped tossing and turning. Cannot recommend enough.

The racing thoughts at bedtime were what stopped me sleeping. CLARIA calmed that down noticeably within 4–5 days. I feel like a different person when I've slept properly.

Three years of broken sleep after a stressful period at work. Eight weeks on CLARIA and I wake up feeling like I've actually rested. That's been new for a very long time.

I travel constantly and jet lag destroyed my sleep. CLARIA is the most consistent sleep support I've found — far better than anything else I've tried and no grogginess in the morning.

Bought on a whim. Did not expect it to work this well. Seven hours, unbroken. Every single night. That hasn't happened in years. I've recommended it to everyone I know.

The quality of sleep has changed, not just the duration. I wake up and feel rested for the first time in years. The difference in how I function during the day is significant.

I wanted to come off prescription sleep aids. My GP suggested trying a supplement first. CLARIA worked better than I expected. Three months in and sleeping well.

I manage a lot of anxiety and my sleep was the main casualty. CLARIA has helped me wind down properly and stay asleep. Really thoughtfully formulated — you can tell it's not just a single ingredient job.

Bought for my husband who has terrible sleep. He's now sleeping 7–8 hours without waking. He'd tried melatonin, magnesium, all of it. Nothing worked until CLARIA.

Common questions
Melatonin is a single hormone that tells your body it's night-time — useful for jet lag but it doesn't address why you can't sleep. CLARIA targets the three upstream causes of sleep disruption: elevated cortisol, low GABA activity, and an overactive stress response. The combination of six ingredients is what makes it effective for persistent sleep problems that melatonin alone hasn't fixed.
No. CLARIA contains no sedatives or antihistamines — the compounds that cause morning drowsiness. It works by supporting your body's own wind-down mechanisms rather than forcing sedation. Most customers describe waking feeling refreshed rather than foggy.
Most people notice they fall asleep faster within 3–5 days. Night waking typically reduces by day 7–10. The fuller quality-of-sleep improvement becomes consistent by week 3–4 with daily use. Some people notice a difference from night one; others need the full two weeks for the cortisol-lowering effect to build.
No. None of the six ingredients create dependency or tolerance. You can take CLARIA nightly, take breaks, or stop entirely without withdrawal — it supports your body's natural sleep mechanisms rather than overriding them.
CLARIA is generally well tolerated alongside common supplements. If you take prescription medication — particularly blood thinners, sedatives, or antidepressants — consult your GP before starting, as Valerian and Ashwagandha may interact with some medications.
Yes. CLARIA is 100% vegan. All capsules use a plant-based HPMC shell. The formula is also gluten-free, dairy-free, and soy-free with no artificial colours, fillers, or flow agents.
You deserve a full night's sleep.
CLARIA is risk-free for 30 nights. If it doesn't improve your sleep, you pay nothing. No forms. No questions.
