- 100 % natural & non-habit-forming — Safe for nightly use with no fillers or harsh sedatives.
5 Stages Of Sleep
The 5 Stages of Sleep
REM - Rapid eye movement sleep - This sleep stage is associated with highly active brain functions, dreaming, calm body, erratic breathing and irregular heart rate.
Stage 1 (Drowsiness) - This sleep stage is associated with light sleep. Your eyes are closed, heartbeat and breathing are slow, muscles are relaxed, body temperature drops, brain wave activity slows but you can easily wake up.
Stage 2 (Non-REM Light Sleep 10-25 minutes) - This sleep stage is the period of light sleep before you enter deeper sleep. Your heart rate slows and your body temperature drops.
Stage 3 (Deep Sleep Lasts a few minutes) - This sleep stage prepares you for stage 4.
Stage 4 (Sleep Drowsiness 20-40 minutes) - This sleep stage is where the brain waves are slowest and you have difficulty to wake up. Your body releases growth hormone and helps heal damaged tissue. You want to spend as much time in this stage as possible.

Synergy Highlights / How It Works
Synergy Highlights
| Synergy Pair / Complex | Mechanistic Interaction | Expected Sleep Benefit | Key Reference |
|---|---|---|---|
| Melatonin + 5-HTP + Zinc | Precursor (5-HTP) & co-factor (Zn) sustain endogenous melatonin → prolonged MT1/MT2 signalling | Longer unbroken sleep & smoother REM cycling | Ferracioli-Oda 2013; Rondanelli 2011 |
| GABA + L-Theanine | Dual GABAA modulation & α-wave promotion | Faster sleep-latency, calmer mind | Abdou 2006; Ozeki 2019 |
| Honokiol + Zizyphus + L-Tetrahydropalmatine | BZD-site GABAA agonism + D2 down-shift → additive anxiolytic sedation | Deeper NREM without next-day grogginess | Shinomiya 2012; Zhang 2019 |
| Magnesium Glycinate + Glycine + Taurine | NMDA antagonism & membrane stabilisation; muscle-relaxant triad | ↑ Slow-wave (N3) depth & overnight HRV | Abbasi 2012; Yamadera 2007; Lin 2010 |
| Piperine + Botanical Matrix | CYP3A4 / P-gp inhibition → 2–3× plasma AUC of honokiol, melatonin & apigenin | Quicker onset at lower milligram load | Shoba 1998; Borrelli 2021 |
Summary of Synergy Benefits
DeepSleep™ layers circadian cues, inhibitory neurotransmission, botanical anxiolytics, muscle-nerve relaxants, and bio-enhancers. These synergistic complexes accelerate sleep onset, deepen restorative stages, and extend REM—delivering fuller recovery without pharmaceutical sedatives.
The result is faster, deeper, and cleaner sleep with a compact 4-capsule nightly dose.

Performance Testing
Performance In-House Bench (pilot n = 10)
| Endpoint | Protocol | Mean Result (±95 % CI) |
|---|---|---|
| Time-to-Sleep Onset | Polysomnography, single bedtime dose (4 caps) | 18 min (15 – 21 min) |
| Total Sleep Time | PSG, 8-h window, night 1 | +42 min (+27 – +57 min) |
| Deep-Sleep (N3) Share | EEG staging, night 1 | +17 % (+12 – +22 %) |
| REM Latency | PSG, night 1 | –12 % (–8 – –16 %) |
| Morning Alertness | Karolinska Scale, 30 min post-wake | +22 % (+16 – +28 %) |
| Heart-Rate Variability (RMSSD) | Wearable ECG, overnight | +15 % (+9 – +21 %) |
What These Numbers Mean
Faster Sleep Onset: Volunteers fell asleep in 18 minutes on average—roughly half the U.S. adult baseline of ~35 minutes—showing DeepSleep’s rapid MT1/MT2 and GABAergic activation.
Longer & Deeper Rest: An extra 42 minutes of total sleep and a 17 % boost in slow-wave (N3) stages translate into improved muscle repair, memory consolidation, and next-day vitality.
REM Optimization: Shorter REM latency (–12 %) suggests smoother cycling into dreaming phases, associated with emotional processing and creativity.
Next-Day Performance: Morning alertness scores rose by 22 %, while HRV—a marker of autonomic recovery—improved 15 %, indicating better stress resilience.
Although this was an open-label pilot (n = 10), the outcomes align closely with peer-reviewed data on the individual ingredient clusters, reinforcing DeepSleep™’s multimodal design.

References: El-Sherif 2022
How soon will I notice long-term benefits?
Many feel better after the first night; cumulative HRV and mood gains accrue over 1–2 weeks.
References: Powell 2020
What if I still can't fall asleep after taking DeepSleep and feel frustrated?
Roughly 10 % of users may have underlying factors—late-day caffeine, blue-light exposure, elevated cortisol, or undiagnosed sleep disorders—that overpower the supplement's effects. Audit evening habits (no caffeine after 2 pm, screen curfew 1 h pre-bed, dark/cool room), practise relaxation routines, and seek professional evaluation if insomnia persists despite consistent 4-caps use.
References: AASM 2024, Sleep Foundation 2024
How many hours of sleep do adults need?
Most adults need 7–9 h nightly for optimal health.
References: CDC, Sleep Foundation
Why can't I fall asleep quickly?
Common causes include stress, caffeine, blue-light exposure & irregular schedules.

Why do I wake up in the middle of the night?
Triggers: sleep apnea, hormonal shifts, late meals, overheated bedroom.
References: Mayo Clinic
What is the best bedtime routine?
Regular lights-out, device-free wind-down, dim lighting, relaxation technique.
References: Harvard Sleep
How does blue light affect sleep?
Blue wavelengths suppress melatonin, delaying circadian onset.
