Framework
The four pillars of restorative sleep
Restorative sleep is the product of four distinct biological systems working in sequence. SOMNO® was formulated to support each — not with a single mechanism, but with ingredients that act across all four.
01
Nervous System Downregulation
Supporting the transition from mental activation into a calmer, more relaxed state.
Key ingredients
- L-Theanine
- Magnesium Glycinate
- Glycine
02
Stress Adaptation
Supporting the body's response to stress and helping regulate prolonged activation.
Key ingredients
- Ashwagandha (KSM-66®)
- Reishi Mushroom Extract
03
Sleep Architecture & Quality
Supporting deeper, more continuous sleep cycles and overnight recovery quality.
Key ingredients
- Apigenin
- Passionflower
- Lemon Balm
- Glycine
04
Recovery Continuity
Supporting the body's natural nightly restoration processes for better next-day recovery.
Key benefits
- Improved recovery quality
- Rested feeling
- Physiological restoration
Mechanism
Understanding overnight recovery
Restorative sleep depends on the body's ability to downshift from a state of alertness and move through coordinated recovery processes in sequence. A night is not uniform: slow-wave sleep dominates the first half, REM lengthens toward morning.
When stress, overstimulation or irregular schedules keep the nervous system activated, that sequence gets disrupted — recovery quality can be compromised even when total sleep time looks adequate.
Stage proportions describe a typical healthy adult night and vary with age, schedule and sleep debt. Shown for explanation of sleep architecture, not as a claim about any product.
The research findings
Every ingredient maps to a measurable stage of the night
A night follows a sequence: you fall asleep (latency), stay asleep (efficiency), cycle through slow-wave sleep (physical repair) and REM (emotional processing), then wake restored. Each active in SOMNO was selected against a specific, measurable stage of that sequence — and included at the dose used in the published research.
01 — CNS
Brain & central nervous system
Alpha-wave activity, GABA-A signalling and REM architecture. L-theanine, passionflower, apigenin, lemon balm.
02 — HPA axis
Stress response
Cortisol regulation during prolonged activation. KSM-66® ashwagandha, reishi.
03 — Thermoregulation
Core body temperature
The nightly temperature drop that signals sleep onset. Glycine.
04 — Neuromuscular
Muscle & nerve function
Contributes to normal muscle function and the reduction of tiredness. Magnesium bisglycinate.
01 — Sleep latency
Glycine, 3 g — time taken to fall asleep
What it is
Sleep latency is how long it takes to fall asleep once you're in bed. Glycine is an inhibitory amino acid that lowers core body temperature — the primary physiological signal the brain uses to initiate sleep onset.
Finding
In polysomnography-measured trials, glycine at 3 g before bed shortened sleep onset latency and reduced next-day fatigue compared with placebo. (Neuropsychopharmacology, 2007)
Why it matters
Less time lying awake means more of your time in bed spent in restorative cycles — which matters most when the window is short.

02 — Sleep efficiency
KSM-66® ashwagandha, 600 mg — staying asleep
What it is
Sleep efficiency is the share of time in bed actually spent asleep — the measure of whether the nervous system is letting the body stay in sleep, not just enter it.
Finding
Ashwagandha extract improved sleep efficiency and reduced wake after sleep onset (WASO), alongside reductions in salivary cortisol in adults under chronic stress. (Cureus, 2019)
Why it matters
A stressed nervous system blocks every other mechanism. Efficiency is the measure of whether the hours in bed are real sleep or restless ones.

03 — Slow-wave sleep
Reishi and glycine — share of the night in deep sleep
What it is
Deep sleep (slow-wave sleep) is when the body repairs tissue, restores energy and strengthens immune function — and when the glymphatic system clears metabolic waste from the brain.
Finding
Reishi extract has been associated with a greater proportion of the night spent in slow-wave sleep and less next-day fatigue relative to control. (J Med Food, 2011)
Why it matters
More slow-wave sleep means better physical recovery and less fatigue the following day — regardless of when that day begins.

04 — REM continuity
Passionflower and L-theanine, 200 mg — REM cycles
What it is
REM sleep is when the brain processes memory, emotion and learning — the stage where psychological recovery happens and threat responses are modulated.
Finding
Passionflower binds GABA-A receptors at a site distinct from benzodiazepines, and L-theanine promotes alpha-wave activity without sedation; both have been associated with more consolidated REM cycles. (Phytotherapy Research, 2017)
Why it matters
REM continuity shapes focus, mood and emotional balance — how psychologically recovered you feel the next day, whenever that day starts.

05 — Next-day output
Magnesium bisglycinate and glycine — morning energy
What it is
Morning energy is the functional output of the whole night — and the most practical measure of whether sleep has done its job.
Finding
Magnesium supplementation improved sleep quality measures and reduced next-day fatigue, with self-reported energy scores separating from control from day two across a seven-day period. (JRMS, 2012)
Why it matters
The real test of better sleep is how the morning feels. Magnesium contributes to normal muscle function, normal energy-yielding metabolism and the reduction of tiredness and fatigue.

Formulation position
Why SOMNO® is melatonin-free
Many sleep products rely on melatonin to induce drowsiness quickly. SOMNO takes a different approach.
Melatonin is a hormone, and its job is timing: it tells the body when night has arrived. For someone whose nights keep moving, a fixed timing signal is the wrong instrument — and across much of Europe it isn't available over the counter at all.
We focus instead on supporting the systems involved in relaxation, stress regulation and overnight recovery — without overriding the body's own signalling.
That means the formula works on a cumulative basis rather than as a nightly override, and it fits a schedule that changes week to week.
Works with your rhythm
Supports the body's own recovery processes rather than imposing a timing signal on them.
No hormone involved
Nutrients and botanicals only — nothing that acts as a hormonal input.
No sedation hangover
Formulated for wind-down rather than pharmacological sedation.
Built for nightly use
Designed as a consistent evening routine, not an occasional override.
A timing-led approach peaks early, then falls away.
Multi-pathway support is sustained across the full cycle.
