Engineer Your
Sleep Architecture
Target the biological levers of sleep latency, slow-wave depth, and REM stability with clinical-grade pharmacology.
The Melatonin Trap
90% of over-the-counter sleep aids rely on megadoses of Melatonin. Exogenous melatonin at high doses induces a sedative state that suppresses REM and leads to grogginess.

| Magnesium L-Threonate | 145mg | NMDA antagonism |
| Apigenin | 50mg | GABA-A modulation |
Orthomolecular Precision
Sleepcup targets the neurochemical prerequisites for sleep. By modulating GABA, reducing excitatory glutamate, and facilitating the necessary drop in core body temperature.

Permeability is Everything.
A supplement is only as effective as its bioavailability. Traditional magnesium forms (Oxide, Citrate) are poorly absorbed and rarely cross the blood-brain barrier.
Sleepcup utilizes Magnesium L-Threonate (Magtein®), a compound developed at MIT specifically engineered to cross the BBB and directly elevate central nervous system magnesium levels.
Positive Allosteric Modulation
Apigenin acts as a ligand for benzodiazepine sites on the GABA-A receptor. Unlike synthetic benzodiazepines which force the receptor open and cause rapid downregulation (tolerance), Apigenin simply increases the receptor's affinity for your body's endogenous GABA.
Clinical Literature
Our formulation is not based on proprietary blends or mystical herbalism. It is built strictly on published, peer-reviewed pharmacokinetic data.
Alpha Wave Promotion
L-Theanine crosses the blood-brain barrier within 30 minutes of ingestion. By blocking excitatory glutamate and boosting inhibitory GABA, L-Theanine generates Alpha brain waves (8-12 Hz)—the electrical signature of a relaxed, yet alert state.
Why 200mg?
Clinical trials studying L-Theanine for sleep latency consistently utilize doses between 200mg and 400mg. Doses lower than 100mg fail to produce significant differences in EEG alpha power compared to placebo.
The Thermal Drop
Circadian rhythms dictates that core body temperature must fall by approximately 1 to 3°F to initiate and maintain sleep.
Glycine (3g) acts as a peripheral vasodilator. It increases blood flow to the extremities, allowing heat to escape the body rapidly, accelerating the necessary core temperature drop and reducing sleep onset latency.
What we leave out.
Zero Melatonin
As repeatedly stated, exogenous melatonin is a blunt tool that disrupts natural circadian timing. We do not use it.
Zero Antihistamines
Diphenhydramine (found in ZzzQuil/Benadryl) causes profound next-day grogginess and has been linked to long-term cognitive decline due to its anticholinergic properties.
Zero Sugar or Fillers
Sugar spikes insulin, which counteracts the necessary cortisol drop before bed. We use a micro-dose of Stevia leaf extract.
Zero Proprietary Blends
You have the right to know the exact milligram dosage of every active compound you ingest. No hidden "sleep matrix" formulas.
Protecting NREM 3
The first third of the night is dominated by NREM Stage 3 (Slow-Wave Sleep). This is when the brain clears amyloid-beta plaques via the glymphatic system and the pituitary gland releases growth hormone.
The Sleepcup formulation is heavily indexed on protecting this specific phase from micro-arousals (often caused by cortisol or residual caffeine) via NMDA antagonism (Magnesium L-Threonate).

Acquire FormulationCommon Questions
Why is there no Melatonin in Sleepcup?
Melatonin is a hormone, not a vitamin. Chronic supplementation downregulates your body's natural production and shifts your circadian clock rather than improving sleep depth. We focus on neurotransmitter balance (GABA/Glutamate) instead.
Can I take this with my current sleep meds?
Consult your physician. While our ingredients are non-prescription amino acids and minerals, they can have additive sedative effects when combined with prescription hypnotics or benzodiazepines.
When should I take it?
Mix one scoop with 6-8oz of water approximately 45-60 minutes before your intended sleep time. Do not consume with high-calorie meals, which can blunt absorption of the amino acids.
Will I build a tolerance?
No. Unlike synthetic sleep aids that downregulate receptors over time (requiring higher doses), the compounds in Sleepcup (Magnesium, Glycine, Theanine, Apigenin) do not cause physiological dependence or tolerance.
