Our Sleep I formula is engineered to support the body’s natural sleep-wake cycle, relaxation response, and sleep onset at a foundational level.
Designed for consistent nightly use, it helps prepare the nervous system for rest and supports a smooth transition into sleep.
At its core is a low-dose Melatonin (2 mg), supporting the regulation of the circadian rhythm and helping the body wind down naturally at night without excessive sedation.
This is combined with GABA and L-Tryptophan, supporting neurotransmitter activity associated with relaxation and sleep readiness, helping the mind and body transition into a restful state.
The formula is further supported with targeted calming ingredients designed to assist with relaxation and pre-sleep downregulation.
Our Sleep I formula is designed for daily use to build consistent sleep quality, improve relaxation, and support natural overnight recovery.
The Science
Evidence-Based Formulation
Every ingredient in Sleep I is selected based on peer-reviewed clinical research — a gentle, non-habit-forming blend of herbal extracts, amino acids and low-dose melatonin for natural sleep onset.

Benefits

- Non-habit-forming with no next-day grogginess
Why our Sleep I
Most sleep supplements use melatonin alone at 5–10mg — doses that override endogenous production rather than supporting it, and which can downregulate pineal melatonin synthesis with consistent use. Sleep I uses a lower 2mg dose alongside six botanicals targeting complementary mechanisms: valerian and passion flower for GABAergic receptor modulation, L-tryptophan as a serotonin precursor feeding the 5-HTP → melatonin biosynthesis pathway, and lemon balm for GABA transaminase inhibition. Multiple sleep pathways addressed, rather than a high melatonin dose doing all the work.

What our customers say.
I was hesitant about taking anything for sleep but the gentle formula here is perfect. Helps me wind down properly, fall asleep naturally and wake up feeling clear. Take it every night without hesitation.
Perfect for anyone who struggles to switch off at night. This doesn't knock you out — it supports your body's natural wind-down process beautifully. Sleep is deeper and I wake up properly rested.
The 2mg melatonin dose is perfect. I've used higher doses before and they left me groggy the next morning. This is gentle enough for every night and really does help me switch off and sleep.
The combination of valerian, passionflower and chamomile alongside the tryptophan is exactly right for a natural sleep formula. Falls asleep within 30 minutes and stays asleep. Excellent.
I struggled with sleep for years and was resistant to anything pharmaceutical. This gentle, natural formula has genuinely helped me establish a proper sleep routine. Life changing.
The L-theanine and GABA together for relaxation is a smart addition to what's already a well-thought-through formula. I'm calmer at bedtime and the quality of sleep is noticeably better.
Works beautifully as part of an evening wind-down routine. I take it 45 minutes before bed alongside magnesium and sleep is consistently better than anything I've tried before.
Perfect for occasional use and regular use alike. Doesn't leave you dependent and doesn't cause grogginess. This is what a proper sleep supplement looks like.
My racing mind at bedtime has been my main sleep issue for years. This formula specifically addresses that — the theanine and passionflower calm the mind beautifully. Really impressed.
