Ghost - Sleep

Ghost Sleep is Ghost Lifestyle's sleep and overnight recovery supplement — a flavored powder taken before bed that targets three distinct goals simultaneously: improving sleep onset and sleep architecture, supporting overnight physical recovery, and reducing the stress and cortisol burden that prevents deep sleep and degrades recovery quality. Nine active ingredients across those three pillars, transparently dosed, fully disclosed. The formula launched in August 2024 — Ghost's first-ever sleep product despite sleep support being discussed internally since 2021. The delay was deliberate: Ghost CEO Dan Lourenco wanted to get the colostrum sourcing and dosing right before launching. Two scoops per serving, 20 servings per container.

The Three Pillars of Ghost Sleep — How the Formula Is Organized Ghost Sleep is not a standard melatonin + valerian "sleep aid." It is a comprehensive nighttime formula that addresses sleep quality, overnight physical recovery, and pre-sleep stress regulation as three interconnected systems rather than treating sleep onset as the only variable. The nine ingredients are organized into three functional layers that address different aspects of the sleep-recovery equation.† Pillar 1 — Overnight Recovery Colostrum — 3,125mg (yielding 1.25g IgG) Colostrum is the first fluid produced by mammary glands in the days after birth — often called "liquid gold" for its extraordinarily dense concentration of immune factors, growth factors, and bioactive compounds. Ghost Sleep uses bovine colostrum, which contains a profile of bioactive components — Immunoglobulins (especially IgG), growth factors (IGF-1, IGF-2, TGF-beta), lactoferrin, proline-rich polypeptides (PRPs), and a spectrum of hormones and cytokines — that collectively support immune function, gut integrity, and tissue repair.† In the context of overnight recovery from resistance training, colostrum's most relevant properties are its growth factor content and its immune modulation. IGF-1 (Insulin-Like Growth Factor 1) in colostrum directly stimulates muscle protein synthesis and satellite cell proliferation — the same growth factor that GH drives the liver to produce during the nocturnal HGH pulse. Colostrum supplementation at 3g+ daily doses has been studied in athletes with documented improvements in muscle recovery markers, reductions in muscle damage biomarkers, improvements in body composition, and reductions in post-exercise immune suppression. Ghost's 3,125mg dose with confirmed IgG content (1.25g, transparently disclosed on the label) is one of the highest-dosed and most fully disclosed colostrum inclusions in any sleep supplement on the market.† The timing is deliberate: the overnight recovery window during deep sleep is when the body performs the majority of its tissue repair and adaptation from the previous day's training. Colostrum's growth factors and immune factors delivered before sleep position them optimally to support this nocturnal repair process.† L-Glycine — 3,000mg Glycine is a conditionally essential amino acid with two distinct roles relevant to sleep and recovery. As a structural protein component, glycine is the most abundant amino acid in collagen (comprising approximately 33% of collagen's amino acid content) — making it directly relevant to connective tissue repair and maintenance overnight. As a neurotransmitter, glycine functions as an inhibitory neurotransmitter in the spinal cord and brainstem that helps reduce motor neuron excitability and muscle tension during sleep, supporting the physical relaxation necessary for deep sleep.† Glycine's most intriguing documented sleep property is its ability to lower core body temperature through peripheral vasodilation — increasing blood flow to the skin to dissipate heat. Core body temperature drop is one of the primary physiological signals that initiates and deepens slow-wave sleep; a faster and deeper core temperature decline accelerates sleep onset and increases time spent in deep, restorative slow-wave sleep stages. Research on 3g of glycine before bed — precisely Ghost Sleep's dose — consistently shows improvements in sleep quality scores, reductions in daytime sleepiness (indicating better overnight sleep quality), and improvements in cognitive performance the next morning. At 3g, Ghost Sleep provides glycine at the dose used in the positive research.† Pillar 2 — Sleep Onset and Architecture GABA — 1,000mg GABA (gamma-aminobutyric acid) is the primary inhibitory neurotransmitter of the central nervous system — the signal that reduces neuronal excitability and promotes the CNS quieting necessary for sleep. At 1g, Ghost Sleep's GABA inclusion is at the dose used in research documenting relaxation effects, improvements in sleep quality, and modest acute increases in growth hormone secretion. GABA's primary function in Ghost Sleep is reducing the CNS arousal state — the "wired but tired" feeling that prevents sleep onset even when fatigue is present — through direct inhibitory neurotransmitter activity.† Zylaria (Xylaria nigripes Extract) — 500mg Zylaria is a patented ingredient from NuLiv Science derived from Xylaria nigripes, a mushroom used in Traditional Chinese Medicine for insomnia and anxiety. Modern research on Xylaria nigripes has documented two sleep-relevant mechanisms: it is a natural source of GABA (enhancing endogenous GABA levels independent of supplemental GABA) and it has been shown to significantly increase the duration of slow-wave (deep) sleep — the most restorative sleep stage for physical recovery, memory consolidation, and growth hormone secretion. Research on mice treated with Xylaria documented higher GABA concentrations in the brain alongside improved sleep metrics. The combination of Zylaria's endogenous GABA enhancement with Ghost Sleep's 1g of supplemental GABA creates a dual approach to GABAergic sleep support that covers both exogenous delivery and endogenous synthesis stimulation simultaneously.† L-Tryptophan — 500mg L-Tryptophan is an essential amino acid and the direct dietary precursor to serotonin — the neurotransmitter responsible for mood regulation, relaxation, and the subjective sense of well-being. Serotonin is in turn converted to melatonin through a two-step enzymatic process (hydroxylation to 5-HTP, then decarboxylation to serotonin, then N-acetylation to N-acetylserotonin, then O-methylation to melatonin). Providing L-Tryptophan before bed therefore supports both serotonin-mediated mood and relaxation and endogenous melatonin synthesis — complementing the exogenous melatonin in Ghost Sleep by supporting the body's own melatonin production pathway simultaneously.† Tryptophan is particularly relevant for athletes who eat lower-tryptophan diets (plant-based or limited meat intake) and for those who experience elevated catecholamine levels after evening training — catecholamines and tryptophan compete for the same blood-brain barrier transport, so elevated post-workout dopamine and norepinephrine can temporarily reduce brain tryptophan uptake and delay the serotonin/melatonin cascade that signals sleep readiness.† Melatonin — 3mg Total (1.5mg Immediate + 1.5mg MicroActive Sustained Release) Ghost Sleep uses a dual-delivery melatonin system: 1.5mg of standard immediate-release melatonin for fast sleep onset, and 1.5mg of MicroActive Sustained Release Melatonin — a patented microencapsulated form that releases melatonin gradually over an extended period. The immediate-release fraction addresses sleep latency (getting to sleep faster), while the sustained-release fraction maintains melatonin availability throughout the night to support sleep continuity and reduce middle-of-the-night awakening. This biphasic approach addresses two distinct sleep problems that a single-release melatonin cannot solve simultaneously — it is qualitatively more sophisticated than standard 3mg or 5mg immediate-release melatonin formulations.† Pillar 3 — Stress and Cortisol Reduction KSM-66 Ashwagandha — 600mg KSM-66 is the most extensively clinical-trial-validated ashwagandha extract available — a full-spectrum root extract (not leaf or combined plant part) standardized to ≥5% withanolides. Ashwagandha is classified as an adaptogen for its documented ability to modulate the HPA (hypothalamic-pituitary-adrenal) axis — the hormonal pathway that governs cortisol production and the stress response. Elevated cortisol in the evening is one of the primary biochemical obstacles to quality sleep: cortisol is the "alert" hormone that opposes the relaxation and sedation signals that prepare the body for sleep. Athletes who train intensely in the evening are particularly susceptible to elevated late-night cortisol.† KSM-66 at 600mg — precisely the dose used in the majority of positive clinical trials — consistently shows reductions in serum cortisol, improvements in subjective stress and anxiety scores, and improvements in sleep quality metrics including sleep onset latency, total sleep time, and sleep efficiency. The 600mg dose is the established clinical benchmark for KSM-66's stress and sleep effects.† SerinAid Phosphatidylserine — 400mg (delivering 200mg PS) SerinAid is Chemi Nutra's trademarked form of phosphatidylserine (PS) — a phospholipid that is a critical structural component of neuronal cell membranes and a well-documented cortisol modulator. PS supplementation has been shown in multiple clinical trials to reduce exercise-induced cortisol elevations by 20-30% and to improve the cortisol-to-testosterone ratio — the hormonal balance that determines whether a training stimulus produces muscle growth (high testosterone-to-cortisol) or muscle breakdown and fatigue (low testosterone-to-cortisol). In the sleep context, PS's cortisol blunting effect creates a more favorable evening hormonal environment for sleep onset by reducing the cortisol arousal signal that opposes melatonin's sleep initiation. At 400mg SerinAid delivering 200mg active PS, Ghost Sleep is in the range where cortisol reduction and cognitive recovery effects have been documented.† Magnesium — 200mg Magnesium is the fourth most abundant mineral in the human body and is increasingly recognized as directly impactful on sleep quality — with estimates suggesting that a significant percentage of American adults are magnesium deficient. Magnesium's sleep relevance operates through several mechanisms: it is a required cofactor for GABA receptor binding (meaning GABA's inhibitory effects on the CNS depend on adequate magnesium for full receptor activation), it activates the parasympathetic nervous system (the "rest and digest" state that opposes the "fight or flight" sympathetic arousal), it supports the melatonin synthesis pathway, and it directly relaxes muscles by antagonizing calcium at muscle cell channels — reducing the muscle tension and restlessness that can impair sleep quality. Athletes have higher magnesium requirements than sedentary individuals due to sweat losses and elevated utilization during training, making deficiency more common and supplementation more relevant.† The Colostrum Decision — Why Ghost Sleep Is Different Including colostrum in a sleep supplement is Ghost's most creative formulation decision in Ghost Sleep — and it reflects Ghost's broader approach to product development, which is to look for ingredients that address the actual problem rather than just the symptom. The actual problem for athletes isn't only "hard to fall asleep" — it's "hard to fall asleep AND not recovering adequately despite adequate sleep hours." Conventional sleep supplements address the first problem exclusively. Ghost Sleep addresses both.† The colostrum delay — Ghost first discussed a sleep product in 2021, did not launch until 2024 — was publicly attributed by Dan Lourenco to sourcing and formulation challenges with getting colostrum right in a flavored powder product at a meaningful dose with full transparent IgG content disclosure. The resulting product has 3.125g of colostrum with a disclosed 1.25g IgG per serving — an unusually high dose and an unusually transparent disclosure for the supplement industry, where colostrum is often included at 300-500mg without IgG content specified.† Frequently Asked Questions About Ghost Sleep Why is the serving size 2 scoops and why should new users start with 1? The 2-scoop serving delivers the full clinical doses of all nine active ingredients — particularly the 3g glycine, 3.1g colostrum, and the full melatonin + GABA stack. At one scoop (half serving), all doses are halved. Ghost recommends the half-serving starting protocol because the combined sedative effect of GABA, melatonin, Zylaria, glycine, and KSM-66 can be more potent than expected for users who are not habituated to multi-ingredient sleep supplements. Starting with one scoop allows calibration of individual response — some users find one scoop sufficient, while others prefer the full two-scoop serving for maximum effect. Do not take more than 2 scoops per day.† Will Ghost Sleep cause grogginess the next morning? The dual-release melatonin system (1.5mg immediate + 1.5mg MicroActive sustained) is specifically designed to minimize next-morning melatonin carryover compared to high-dose single-release melatonin products. Most users report feeling refreshed rather than groggy when Ghost Sleep is taken with a full night of sleep (7-9 hours). The glycine in the formula actively contributes to next-morning alertness and cognitive performance — research on glycine before bed consistently shows reductions in daytime sleepiness the following day. However, individual response varies: users who cannot commit to a full sleep duration should avoid taking Ghost Sleep, and those sensitive to melatonin at any dose should assess carefully at the half-serving before committing to the full 3mg.† Can I take Ghost Sleep alongside other Ghost wellness products? Ghost Sleep stacks cleanly with Ghost Joint (different timing — joint is daily, sleep is bedtime), Ghost Glow Sticks (daily, any time), and Ghost Greens. It is not appropriate to combine with any other melatonin-containing product or any other sedative sleep supplement. Do not combine with alcohol — the interaction between GABA, melatonin, and alcohol's own CNS depressant effects can produce unpredictable sedation intensity. Ghost Sleep is for bedtime use only.† Is Ghost Sleep appropriate for daily use or just occasional sleeplessness? Ghost's label states "use for occasional sleeplessness" — this is standard regulatory language for melatonin-containing products. Practically, the non-melatonin ingredients (colostrum, glycine, KSM-66, phosphatidylserine, magnesium, GABA) are appropriate for daily consistent use and produce benefits that accumulate over time with daily supplementation. The melatonin component at 3mg is in a range where nightly use is generally considered safe for adults, though some practitioners recommend cycling melatonin periodically to maintain natural melatonin receptor sensitivity. Consult a physician if you intend to use Ghost Sleep nightly for extended periods.† How to Take Ghost Sleep Mix 2 scoops with 6-8oz of water 30-60 minutes before bedtime. New users start with 1 scoop to assess tolerance. Do not exceed 2 scoops per day. Do not use with alcohol. Do not drive or operate machinery after taking. Only for use at bedtime. Ensure you have 7-9 hours of sleep time available. Do not take if pregnant or nursing.
