Revive MD Sleep is a melatonin-free sleep support formula built entirely on GABAergic, non-hormonal ingredients dosed at the levels used in the actual clinical research behind each one — 3,000mg of L-Glycine (the exact dose used in published sleep research), 2,000mg of Inositol, 200mg of L-Theanine, and 400mg of Magnesium from two chelated forms (Magnesium Bisglycinate and Magnesium Taurate). Unlike melatonin supplementation, which can disrupt natural hormone production or cause morning grogginess, Revive MD Sleep works with your body's own natural processes to promote relaxation, reduce how long it takes to fall asleep, and enhance overall sleep efficiency — without the "hangover" effect some people experience with melatonin. Non-habit forming. Vegan-friendly, gluten-free, soy-free. Informed Sport Certified. 30 servings per container. Flavors: Honey Lemon and Dark Chocolate. Start with 1 serving to assess effects; can increase to 2 servings per evening if needed. Take in the evening about 30 minutes prior to optimal sleep time. California Prop 65 Warning applies.†

Why Revive MD Skipped Melatonin
Revive MD Sleep is deliberately melatonin-free — and this is a formulation decision, not an oversight. Melatonin is a hormone, and supplementing with it can disrupt the body's own natural melatonin production over time, and commonly produces morning grogginess or a lingering "hangover" effect the next day. By building the formula entirely around GABAergic compounds instead — ingredients that support the body's own inhibitory neurotransmitter system rather than introducing an exogenous hormone — Revive MD Sleep is positioned specifically as a daily driver sleep aid, appropriate for consistent nightly use without the hormonal disruption risk that comes with regular melatonin supplementation. For anyone who specifically wants melatonin in their sleep stack, Revive MD's sister brand RAW Nutrition offers RAW Sleep, which does include it — giving customers the choice rather than forcing one approach.†
The Four Ingredients — All at Clinical Doses
L-Glycine — 3,000mg — The Exact Clinical Sleep Dose
Glycine is a conditionally essential amino acid with GABAergic effects — it acts on the central nervous system similarly to GABA itself, the primary inhibitory neurotransmitter responsible for calming neural activity. Studies consistently show that the clinical dose of glycine for improving sleep is 3 grams, and Revive MD Sleep uses exactly that dose. A 2006 randomized controlled trial found that subjects taking a glycine supplement before bed experienced higher quality sleep and more energy upon waking compared to placebo. A follow-up 2007 randomized single-blind crossover study using 3g of glycine documented improvements across multiple validated sleep quality inventories (Pittsburgh Sleep Quality Index, St. Mary's Hospital Sleep Questionnaire, Stanford Sleepiness Scale) — subjects fell asleep faster and had less trouble getting to sleep. Using actual polysomnography data, that same study documented longer deep sleep duration and significantly fewer nighttime awakenings in the glycine group, along with improved next-day wakefulness and memory test performance. A 2012 follow-up study found the cognitive benefits of glycine persisted for several days after supplementation.†
Inositol — 2,000mg — Circadian Rhythm and GABA Receptor Support
Inositol is a carbohydrate-like compound that supports healthy neurotransmitter function, particularly serotonin and dopamine — both crucial for mood regulation and relaxation. It has been studied for effects on anxiety and depression, conditions that frequently disrupt sleep patterns, with some research indicating supplementation may reduce sleep onset latency and increase overall sleep duration. Inositol also participates in the phosphatidylinositol signaling pathway, which directly influences GABA receptor function — upregulating GABA activity to calm the nervous system and improve both sleep onset and quality. Research additionally suggests myo-inositol plays a role in regulating the intracellular signaling mechanisms that govern circadian rhythm, potentially helping maintain a more consistent sleep-wake cycle over time.†
L-Theanine — 200mg — The Research-Standard Dose
L-Theanine, an amino acid from Camellia sinensis (true tea), acts as a GABAergic neurotransmitter in the central nervous system, producing calming, anti-anxiety effects through its inhibitory action on neurons. At 200mg — the standard dose repeatedly verified in peer-reviewed sleep research — theanine has documented effects on shortening sleep onset (falling asleep faster) and improving overall sleep quality. One study found 200mg of theanine taken daily for four weeks improved PSQI scores by approximately 2 points on the 21-point scale — a statistically significant improvement — while also improving verbal fluency and cognitive performance in stressed subjects. Theanine's sleep benefit is partly attributed to its ability to decrease cortisol production, the body's primary stress hormone; elevated cortisol is a well-documented disruptor of both sleep onset and sleep quality.†
Magnesium — 400mg, Dual Chelated Forms
Magnesium is an essential electrolyte involved in over 600 metabolic processes, and Revive MD went with a full, meaningful 400mg dose — notably higher than the token amounts magnesium is typically included at in multi-ingredient sleep formulas. Magnesium plays a crucial role in neurotransmitter production, particularly GABA — supporting GABA signaling directly improves sleep quality, especially for those experiencing poor sleep linked to stress. Beyond sleep specifically, magnesium has documented effects on reducing cortisol, supporting muscle relaxation, and — for physically active people who sweat heavily — replacing the magnesium lost through perspiration during training. Revive MD uses two chelated forms specifically: Magnesium Bisglycinate Chelate and Magnesium Taurate. Both are widely recognized for superior absorption and bioavailability compared to cheaper alternatives like magnesium oxide, with minimal risk of the GI upset that lower-quality magnesium forms commonly produce.†
Why Glycine and Magnesium Work So Well Together
Glycine and magnesium are both GABAergic ingredients, meaning they support the same inhibitory neurotransmitter pathway through complementary mechanisms — magnesium supports the neurotransmitter machinery that produces GABA, while glycine directly activates GABA-like receptor activity itself. Combined with Inositol's GABA receptor-sensitizing effect and L-Theanine's own GABAergic and cortisol-lowering activity, Revive MD Sleep's four ingredients all converge on the same core neurochemical pathway from different angles — a coordinated, multi-mechanism approach to the same physiological goal rather than four unrelated ingredients bundled together.†
Frequently Asked Questions
Why doesn't Revive MD Sleep contain melatonin?
This is a deliberate formulation choice. Melatonin is a hormone, and regular supplementation can disrupt the body's own natural production over time, commonly producing next-day grogginess. Revive MD built Sleep entirely around GABAergic, non-hormonal ingredients specifically so it's suitable as a daily driver sleep aid for consistent nightly use without that hormonal disruption risk. RAW Nutrition (Revive MD's sister brand) offers a melatonin-containing alternative (RAW Sleep) for those who prefer that approach.†Will I feel groggy the next morning?
Unlike melatonin, none of the four ingredients in Revive MD Sleep (Glycine, Inositol, L-Theanine, Magnesium) are sedatives — they work by supporting the body's own relaxation and GABA signaling pathways rather than forcing sedation. This is specifically why the formula is positioned as suitable for daily, ongoing use without the next-day hangover effect some people experience with melatonin or pharmaceutical sleep aids.†Is Revive MD Sleep habit-forming?
No — it is specifically formulated as non-habit forming. All four active ingredients are naturally occurring compounds (an amino acid, a carbohydrate-like compound, another amino acid, and an essential mineral) that support the body's existing physiological processes rather than introducing a foreign sedative compound the body can develop dependency on.†Is Revive MD Sleep appropriate for tested athletes?
Yes — Revive MD Sleep is Informed Sport Certified, with every batch independently tested for banned substances. Glycine, Inositol, L-Theanine, and Magnesium are not prohibited by WADA or NCAA.†
