Our Deep
Most sleep aids use melatonin or magnesium in isolation — one mechanism, one angle. Deep works across multiple biological pathways simultaneously: magnesium citrate and vitamin B6 as essential cofactors for GABA synthesis and nervous system regulation, and 5-HTP from Griffonia simplicifolia as a direct serotonin precursor feeding the melatonin biosynthesis pathway.
L-theanine promotes alpha-wave brain activity and modulates GABA, serotonin, and dopamine pathways for calm sleep onset without sedation. Ashwagandha targets cortisol and HPA axis dysregulation — the root driver of stress-related sleeplessness. At 10mg, the melatonin dose is calibrated for deeper sleep support and circadian entrainment rather than simply supplementing endogenous production. A full-spectrum approach to sleep architecture.
The Experience
What You'll Feel
01
Faster Sleep Onset
Melatonin and botanicals work across GABAergic, melatonergic, and serotonergic pathways simultaneously — not just one mechanism.
02
Deeper Sleep Stages
L-Theanine and GABA promote slow-wave sleep without sedation — research shows L-theanine improves sleep quality and reduces latency without next-day heaviness.
03
Calms Stress-Driven Sleeplessness
Ashwagandha modulates cortisol and the HPA axis — targeting the root driver of stress-related sleeplessness, not just masking symptoms.
04
Full Serotonin-Melatonin Pathway
5-HTP and L-Tryptophan feed melatonin biosynthesis directly, while Vitamin B6 acts as the essential cofactor converting 5-HTP to serotonin.
What to Expect
Results Over Time
Day 1
First Nights
The 10mg melatonin dose begins anchoring your circadian clock from the first night. Some people notice slight morning heaviness in the first 3–5 days as their system adjusts.
Day 7
Building
Any initial morning heaviness typically resolves within 3–5 days, and this is where reviews most consistently mention deeper, more consistent sleep taking hold.
Day 21
Full Effect
Sleep quality and circadian consistency improve progressively over weeks — GABA modulation, HPA axis recalibration, and serotonin pathway support all deepen with consistent use.
The Formula
What's Inside
Serving Size: 2 Capsules · Servings Per Container: 30.
10mg Melatonin plus a 905mg blend of 14 botanicals and amino acids — L-Tryptophan, 5-HTP, GABA, L-Theanine, Ashwagandha, Chamomile, Passionflower, Hops, magnesium citrate and Vitamin B6 among them.
Usage
How to Take It
1
2 Capsules 30–60 Minutes Before Bed
Take 2 capsules 30–60 minutes before bed. The 10mg melatonin dose requires this lead time to bind MT1 and MT2 receptors and begin signalling your circadian clock for sleep onset at the right time.
2
Start With 1 Capsule if You're Melatonin-Sensitive
If you're new to melatonin or sensitive to higher doses, begin with 1 capsule (5mg melatonin) for the first week and build to the full 2-capsule serving. Any morning heaviness typically resolves within 3–5 days as your system adjusts.
3
Avoid Alcohol and Blue Light After Taking
Alcohol interferes with melatonin metabolism and suppresses REM sleep architecture. Blue light exposure after taking Deep counteracts the circadian signalling. A consistent wind-down routine maximises the formula's effectiveness.
The Science
Evidence-Based Formulation
↓ sleep latency
Melatonin Reduces Sleep Onset Latency and Improves Sleep Quality — Systematic Review and Meta-Analysis
A systematic review found melatonin supplementation significantly reduced sleep onset latency and improved total sleep time and sleep quality in multiple RCTs. Melatonin synchronises the circadian clock via MT1 and MT2 receptors in the suprachiasmatic nucleus, making it particularly effective for sleep-onset insomnia and circadian rhythm disruptions including jet lag and shift work.
↑ sleep efficiencyMagnesium Supplementation and Sleep Quality in Adults with Insomnia
A double-blind RCT of magnesium in elderly adults with insomnia found significant improvements in sleep duration (p=0.002), sleep efficiency (p=0.03), and Insomnia Severity Index scores, with melatonin rising and serum cortisol falling — demonstrating a hormone-mediated sleep mechanism through magnesium's role in GABA and nervous system regulation.
↑ sleep qualityL-Theanine and Stress Reduction and Sleep Quality
Research found L-theanine (200 mg/day) improved sleep quality, reduced sleep latency, and lowered anxiety scores versus placebo in adults with high-stress lifestyles. It promotes alpha-wave brain activity and modulates GABA, serotonin, and dopamine pathways without causing sedation — supporting calm, restful sleep onset.
↓ sleep latencyL-Tryptophan Reduces Sleep Onset Latency in Chronic Insomniacs — Double-Blind Trial
A double-blind study found evening L-tryptophan administration to chronic sleep-onset insomniacs produced a significant, late-appearing reduction in sleep latency. L-tryptophan is the dietary precursor to both serotonin and melatonin — the core neurochemical pathway governing sleep induction — and this dose-dependent response provides mechanistic evidence for tryptophan's role in supporting natural sleep onset.
↑ sleep qualityPassionflower Herbal Extract Significantly Improves Subjective Sleep Quality — Double-Blind Placebo-Controlled Trial
A double-blind, placebo-controlled trial found that nightly Passiflora incarnata (passionflower) herbal extract produced significantly better subjective sleep quality on the Sleep Quality Scale versus placebo. Passionflower modulates GABA-A receptors via chrysin and other flavonoids — the same pathway as benzodiazepines — without next-day sedation, dependency risk, or rebound insomnia.
↑ serotonin synthesisPyridoxine (Vitamin B6) Modulates Serotonin Synthesis Rate in the Brain — PET Study
A PET study using radiolabelled tryptophan confirmed that pyridoxine (vitamin B6) modulates serotonin synthesis rate in the brain. As the essential coenzyme for aromatic amino acid decarboxylase, B6 governs the conversion of 5-HTP to serotonin — making adequate B6 status critical for serotonin production and, downstream, melatonin synthesis, sleep onset, and mood regulation.

Questions
Frequently Asked Questions
When should I take it?
2 capsules 30–60 minutes before bed. The 10mg melatonin dose requires this lead time to bind MT1 and MT2 receptors and begin signalling your circadian clock for sleep onset at the right time.
Is 10mg melatonin too strong for me?
If you're new to melatonin or sensitive to higher doses, begin with 1 capsule (5mg melatonin) for the first week and build to the full 2-capsule serving. Any morning heaviness typically resolves within 3–5 days.
Can I drink alcohol or use screens after taking it?
Avoid both — alcohol interferes with melatonin metabolism and suppresses REM sleep architecture, and blue light exposure after taking Deep counteracts the circadian signalling. Do not take with alcohol or sedating medications.
Is it made in a certified facility?
Yes — made in an FDA registered facility in the USA, with no fillers.
Can I cancel my subscription anytime?
Yes — skip or cancel anytime from your account, no lock-in and no phone calls required.

I tried a milder formula first and it wasn't quite enough. Deep is exactly what I needed — deeper, more restorative sleep every night. The stronger formulation makes a clear difference.
I work shifts and managing sleep at irregular hours has always been hard. Deep has genuinely helped me get proper rest regardless of when I take it. The combination is comprehensive and effective.
Good product — I'd say start with 1 capsule (5mg melatonin) if you're sensitive and work up. The full 2-capsule dose (10mg) is very effective for me but some people might find mornings slightly heavy until they adjust.
The 5-HTP alongside tryptophan is a thoughtful detail — it supports the full serotonin-melatonin pathway rather than just one point. Shows the formula was built with real understanding of sleep biochemistry.
I train hard and sleep quality is critical for recovery. Since starting Deep my recovery has improved measurably — deeper sleep, fewer wakeups, and genuinely rested mornings.
The magnesium citrate for physical relaxation alongside the melatonin and botanicals is the right approach. Both the body and mind need to wind down together — this formula addresses both.
Sleep was genuinely awful before this. I'm now consistently getting seven to eight hours of deep, restorative sleep and waking up recovered. One of the most impactful supplements I've taken.
