A sleep supplement — without melatonin
Your body is exhausted. Your mind won't switch off.
Drag the sky to night.
Tone helps your body make that shift for real — four studied ingredients, no melatonin. Meet them below.
Ingredient 01
Ashwagandha
The body-stress ingredient
When you're wired but tired, elevated stress is often what keeps you up. We use a full-spectrum, root-only ashwagandha extract — the most-studied form on the market — chosen to support healthy cortisol levels and the body's resilience to everyday stress, so your system can actually settle before bed.
In randomized, double-blind, placebo-controlled trials of 600 mg/day ashwagandha root extract, participants showed significant reductions in perceived-stress scores and serum cortisol versus placebo (Chandrasekhar 2012). A later 600 mg/day trial in adults with sleep complaints reported improved sleep-onset latency, sleep efficiency, and sleep quality (Langade 2019).

Ingredient 02
Saffron
The sleep-quality differentiator
Saffron is the ingredient almost no sleep supplement includes. We use a premium, standardized saffron extract — hand-harvested from the crocus flower's crimson threads — studied specifically for sleep quality and a calm, balanced mood at a precise 28 mg dose.
In a randomized, placebo-controlled trial, adults with poor sleep taking 28 mg/day of a standardized saffron extract reported improved sleep-quality scores after 28 days, with benefits emerging as early as 7 days — and it was well tolerated, with no next-morning grogginess (Lopresti 2020).

Ingredient 03
L-Theanine
The racing-mind ingredient
The amino acid found in green tea, in a pure, high-quality form. It's the answer to mental chatter — L-theanine is studied to promote a state of calm, relaxed focus without sedation, so the mind quiets down while you stay clear-headed, not knocked out.
Studies of 200 mg L-theanine show increased alpha brain-wave activity — the signature of relaxed alertness — within roughly 30–45 minutes. A randomized controlled trial of 200 mg/day in healthy adults reported improved sleep quality and lower stress-related symptom scores (Hidese 2019).

Ingredient 04
Magnesium Bisglycinate
The foundation
Magnesium is involved in hundreds of processes tied to nervous-system regulation and GABA activity — and many adults simply run short. We use the bisglycinate (glycine-bound) form for gentle absorption without the digestive upset of cheap magnesium oxide, and glycine itself carries its own sleep-supportive research.
In a randomized controlled trial, older adults with poor sleep taking supplemental magnesium improved their insomnia-severity scores, total sleep time, and sleep efficiency versus placebo (Abbasi 2012). Non-buffered bisglycinate is chosen for absorption and tolerability over common magnesium oxide.

Why we're called Vagus Sleep
Real sleep doesn't start in your head. It starts in your nervous system.
Your vagus nerve is the longest nerve of your parasympathetic nervous system — the "rest and digest" branch that runs from your brainstem down to your heart and gut. It's the switch that pulls your body out of "fight or flight" and into the calm, settled state that has to come before sleep is even possible.
Most sleep aids skip that step and simply sedate you. We named the brand Vagus Sleep because we believe the better path is to help your body do what it's built to do — slow the heart rate, ease the stress response, quiet the racing mind — so sleep arrives on its own. Every ingredient in TONE is chosen to support that natural wind-down, not force it.
Our mission
Help people reclaim real rest — without hormones or trade-offs.
Too many people are stuck tired-but-wired — reaching for melatonin or something stronger, then waking up foggy. We're building Vagus Sleep to be the calm, honest alternative: clean formulas, clinically studied ingredients at the doses the research actually used, and nothing hidden behind a "proprietary blend." No melatonin, no grogginess, no dependence — just a nervous system that finally knows how to power down.
Four ingredients. One nightly ritual.
Everything you need to wind down. No melatonin.
Ashwagandha for stress, saffron for sleep quality, L-theanine to quiet the mind, and magnesium bisglycinate as the foundation — each dosed to match the research, in two clean capsules a night.
