Core Sleep's GABA + Venetron® + Valerian stack is clinically shown to shorten sleep latency. Venetron® amplifies GABA's receptor activity; Valerian prevents GABA from breaking down too quickly.
Sleep + Calm adds 200mg L-theanine clinically shown to produce alpha brain waves within 30–60 minutes, creating the same neurological calm as meditation that quiets an anxious mind before sleep.
Sleep + Restore's MicroActive® sustained-release melatonin maintains sleep pressure across the full night, specifically targeting waking after sleep onset not just sleep initiation.
Venetron® has been clinically shown to specifically increase deep non-REM sleep the most restorative stage rather than simply inducing drowsiness or sedation.
Sleep + Calm addresses both dimensions of stress-driven insomnia: L-theanine handles acute arousal fast, while Sensoril® Ashwagandha lowers chronic cortisol the hormone keeping you physiologically alert at night.
Sleep + Restore was designed for circadian disruption. Dual-release melatonin resets the body clock from any starting point; Tart Cherry reinforces the reset with natural melatonin precursors.
Valerian Root at 300mg is clinically shown to reduce night waking and Wake Time After Sleep Onset. Combined with GABA and Venetron®, Core Sleep supports full-night uninterrupted sleep architecture.
A published RCT showed GABA + L-theanine combined increased total sleep time by 22.4% and NREM sleep by 28.8% significantly more than either ingredient alone. Sleep + Calm is built on this synergy.
Melatonin is the clinical gold standard for circadian re-synchronisation. Sleep + Restore's dual-delivery system provides immediate-onset signalling plus sustained coverage across any time zone shift.
Core Sleep is 100% melatonin-free. Melatonin is the leading cause of next-day grogginess in sleep supplements. Our botanical formula produces natural, non-sedating sleep without the morning hangover.
L-theanine raises brain levels of GABA, dopamine, and serotonin simultaneously a compound calming effect that directly addresses the neurological overactivity behind a racing mind.
Sleep + Restore re-anchors a disrupted circadian rhythm: melatonin provides the external time cue, while Tart Cherry's proanthocyanidins increase the body's own melatonin precursor supply.

Venetron® (Rafuma Leaf Extract) - 50mg
A patented botanical extract backed by 6 clinical trials and over 20 published research papers. Venetron® works through two distinct mechanisms: it inhibits the degradation of serotonin (preserving the precursor to your body's natural melatonin production) and acts as a direct GABA receptor agonist, enhancing the calming signals in your brain.
Mechanism of Action
Inhibits serotonin degradation via MAO-A pathway modulation; acts as a direct agonist at GABA-A receptor sites. No CYP3A pathway interaction, meaning no known drug interaction risk.
Clinical Evidence
A 2025 Radicle Science randomized controlled trial (n=370 US adults) confirmed significant improvements in sleep quality, stress, and anxiety versus placebo. Backed by 6 published clinical trials total.
Why This Ingredient Alone Isn't Enough
Clinical data showed that Venetron® alone failed to reduce stress markers in isolation. Its GABA receptor agonist activity requires sufficient GABA to be present at the receptor site to produce meaningful calming effects. Without supplemental GABA and Valerian Root to sustain GABA levels, Venetron®'s receptor binding action is limited.
How It Works In This Formula
In Sonnet's formula, Venetron® activates GABA receptors while supplemental GABA provides the neurotransmitter pool and Valerian Root extends its active window. This validated three-part GABAergic interaction agonism + supply + enzyme inhibition is why the combination succeeded in clinical testing where the individual ingredients did not.
Sleep Problems Addressed
Difficulty falling asleep
Restless or anxious mind at bedtime
Low serotonin-related sleep disruption
Shallow or non-restorative sleep
GABA (Gamma-Aminobutyric Acid) - 100 mg
The brain's primary inhibitory neurotransmitter. At 100 mg, oral GABA has been shown to shorten sleep latency (the time it takes to fall asleep) and increase non-REM sleep time. EEG studies confirm increased alpha brain wave activity within 30 minutes of oral intake, reflecting a calm but alert state that transitions smoothly into sleep.
Mechanism of Action
Works via both direct CNS transport across the blood-brain barrier and indirect gut-brain axis signaling. Potentiated by Venetron® (GABA receptor agonist) and Valerian Root (inhibits GABA transaminase), creating a layered GABAergic effect.
Clinical Evidence
EEG studies demonstrate increased alpha wave activity within 30 minutes of intake. Published research shows reduced sleep onset latency and increased non-REM sleep at 100 mg. A separate RCT demonstrated that GABA + L-Theanine increased total sleep time by 22.4% and NREM sleep by 28.8% significantly more than GABA alone.
Why This Ingredient Alone Isn't Enough
Oral GABA on its own has limited blood-brain barrier penetration, and the neurotransmitter is rapidly metabolized by GABA transaminase. Without Valerian Root inhibiting this enzyme, supplemental GABA's active window is short. Without Venetron® agonizing the receptor, the calming signal at the receptor site is weaker. Clinical data confirms GABA alone failed to reduce stress markers only the combination with Venetron® was effective.
How It Works In This Formula
Valerian Root extends GABA's half-life by blocking GABA transaminase. Venetron® amplifies GABA's effect at the receptor. The result: more GABA available, stronger receptor activation, and slower metabolism a three-layer system that dramatically outperforms GABA supplementation alone.
Sleep Problems Addressed
Long sleep onset latency (taking too long to fall asleep)
Overactive or racing thoughts at night
Insufficient deep sleep / non-REM sleep
General nighttime restlessness
Valerian Root - 300mg
A traditional botanical with well-characterized pharmacology. Valerenic acid, its primary active compound, binds to beta-2 and beta-3 subunits of GABA-A receptors and inhibits GABA transaminase the enzyme responsible for breaking GABA down. This dual action both potentiates and prolongs GABA's calming effect simultaneously.
Mechanism of Action
Dual-action GABAergic support: potentiates GABA receptor response via beta-2/beta-3 subunit binding and extends GABA's active window by inhibiting the enzyme that metabolizes it (GABA transaminase). Also acts as a partial agonist of the 5-HT2A serotonin receptor.
Clinical Evidence
Clinical trials consistently show reduced sleep latency at 300-600 mg. Multiple systematic reviews and meta-analyses confirm efficacy for subjective sleep quality improvement.
Why This Ingredient Alone Isn't Enough
Valerian Root's GABA-extending action is only as effective as the GABA pool it has to work with. Without supplemental GABA to increase the neurotransmitter supply, Valerian is limited to preserving whatever small amount the body produces naturally. And without cortisol modulation (Ashwagandha), the stress hormone override can negate Valerian's calming effects entirely.
How It Works In This Formula
Sonnet's formula, Valerian Root acts as the duration multiplier: it directly extends the active window of supplemental GABA and amplifies the receptor binding of Venetron®. Ashwagandha then ensures cortisol doesn't override this entire GABAergic system.
Sleep Problems Addressed
Difficulty falling asleep
Waking during the night (sleep maintenance)
Non-restorative or shallow sleep
Stress-related sleep disruption
Sensoril® Ashwagandha - 125mg
A clinically-studied, patented ashwagandha extract standardized for bioactive withanolides. Sensoril® modulates the hypothalamic-pituitary-adrenal (HPA) axis, reducing cortisol - the stress hormone that keeps your body in a state of alertness even when you want to sleep. Its effects build over time, meaning the formula becomes more effective the longer you take it.
Mechanism of Action
Reduces serum cortisol by approximately 15% and ACTH (adrenocorticotropic hormone) levels. Modulates the HPA axis to lower baseline stress arousal. By lowering cortisol, it removes the hormonal barrier that prevents GABA and Venetron® from working optimally.
Clinical Evidence
Reduces serum cortisol by approximately 15% and ACTH (adrenocorticotropic hormone) levels. Modulates the HPA axis to lower baseline stress arousal. By lowering cortisol, it removes the hormonal barrier that prevents GABA and Venetron® from working optimally.
Why This Ingredient Alone Isn't Enough
Ashwagandha reduces cortisol but does not directly promote sleep onset. Lowering cortisol removes a barrier to sleep, but without the GABAergic system (GABA + Venetron® + Valerian Root) actively driving calming neurotransmission, the body still lacks a positive sleep-onset signal. Ashwagandha is the "blocker remover," not the sleep driver.
How It Works In This Formula
Sensoril® works as the formula's stress gatekeeper. By lowering cortisol ~15%, it creates the hormonal environment where the GABAergic ingredients can operate at full effectiveness. The longer you take it, the lower your baseline cortisol, meaning the entire formula gets more effective over weeks 2-8.
Sleep Problems Addressed
Stress-induced insomnia
Elevated nighttime cortisol
Difficulty winding down after a busy day
Chronic sleep quality degradation from sustained stress
HPA axis dysregulation
Why not just take each ingredient separately?
Clinical testing showed Venetron® alone failed to reduce stress markers. GABA alone also failed. Only the combination worked. Each ingredient in Core Sleep changes how the others perform the formula is the product.
Night 1–3: Venetron® and GABA begin calming neural activity. Many users notice easier sleep onset within the first few nights.
Days 3–7: Valerian Root's GABA-extending effects build. Sleep onset becomes more consistent and sleep feels deeper.
Weeks 2–4: Sensoril® Ashwagandha's cortisol-lowering effects reach peak levels. Baseline stress decreases and the full formula synergy is realized.
Ongoing: 84% of customers report noticeably improved sleep within the first week. Benefits compound over 4–8 weeks as ashwagandha fully modulates the stress response.
How the Ingredients Work Together
The Core Sleep formula is engineered as a layered GABAergic system reinforced by stress-axis modulation. This is not a collection of individual sleep ingredients it is a validated pharmacological interaction where each component makes the others work better.
Venetron® activates GABA receptors directly while preserving serotonin. Supplemental GABA increases the available neurotransmitter pool. Valerian Root extends GABA's active window by inhibiting the enzyme that breaks it down. Finally, Sensoril® Ashwagandha removes the cortisol barrier that would otherwise override these calming signals.
Clinical data validates this approach: Venetron® alone and GABA alone both failed to reduce stress markers in published research only the combination was effective. This is why Sonnet formulates with ingredient systems rather than standalone compounds.
