NutraBio Sleep Peptides is not a basic melatonin supplement — it's built around a Dual Peptide Sleep Matrix featuring PeptiSleep™ and Lactium®, combined with GABA, L-Theanine, L-Glycine, Albion® Magnesium, and both instant-release and sustained-release melatonin through Melotime™. Every ingredient addresses a different part of the sleep experience, from calming a busy mind to supporting the deep, uninterrupted rest your body needs to recover overnight. Formerly known as Deep Sleep — same trusted formula, new name. The result works with your body, not against it: no grogginess, no dependency, just deep, natural sleep that leaves you waking up feeling like yourself again. Mix 1 scoop with 8-10oz of hot or cold water 30 minutes prior to sleep. Non-habit forming, but due to its potency, cycling is recommended rather than continuous long-term use. Available in Lemon Lavender, Passion Fruit Chamomile, Citrus Honey, and Strawberry Hibiscus.†

The Dual Peptide Sleep Matrix — PeptiSleep™ and Lactium®
PeptiSleep™ and Lactium® form the foundation of this formula's peptide-powered approach to sleep support. Together they work to calm the nervous system, ease mental tension, and support the deep, uninterrupted rest that allows the body and mind to fully recover overnight. Lactium® specifically is a milk-derived bioactive peptide (an enzymatic hydrolysate of casein) studied for its calming, stress-modulating effects — a distinct mechanism from melatonin's circadian-signaling role, addressing the "racing mind" barrier to sleep onset rather than the sleep-wake timing signal itself.†
5g L-Glycine and 2g Taurine — The Amino Acid Foundation
Glycine is a conditionally essential amino acid with documented GABAergic effects — research has repeatedly documented that 3g doses of glycine before bed improve sleep quality, reduce time to fall asleep, and increase next-day alertness; at 5g, Sleep Peptides delivers above this well-studied clinical range. Taurine at 2g contributes its own GABA and glycine receptor-modulating activity, supporting the calming, relaxation-promoting environment that both amino acids work toward from complementary angles.†
GABA, L-Theanine, and Magnesium — Fast-Acting Calm
Sleep Peptides includes fast-acting GABA, L-Theanine, and instant-release melatonin specifically to help calm the mind, relax the body, and ease you into sleep so you can stop counting the hours and start actually resting. GABA at 750mg is the body's primary inhibitory neurotransmitter, directly supporting reduced neural activity for sleep onset. L-Theanine at 200mg — the research-standard dose repeatedly used in published sleep studies — promotes alpha brainwave activity for calm, relaxed alertness without sedation. Albion® Magnesium at 210mg (chelated for superior absorption over cheaper mineral forms) supports GABA receptor function and the muscle relaxation dimension of sleep onset.†
Dual-Source Melatonin — Melotime™ for All-Night Coverage
Falling asleep is only half the equation. Melotime™ sustained-release melatonin works through the night to help maintain a consistent sleep state, so you wake up less and spend more time in deep, restorative rest. By combining 2mg of instant-release melatonin (for fast sleep onset) with Melotime's sustained-release delivery (for maintained melatonin levels through the night), Sleep Peptides addresses both ends of the sleep cycle — falling asleep and staying asleep — rather than the single melatonin spike-and-clear pattern that standard melatonin products produce.†
Why Sleep Peptides Doesn't Leave You Groggy
A common complaint with standard melatonin products is next-day grogginess from an oversized single dose that's still partially active come morning. Sleep Peptides addresses this through its dual-release melatonin delivery system and the broader, multi-mechanism formula — rather than relying on a single large melatonin dose to force sleep, the combination of peptides, amino acids, and dual-release melatonin is designed to work with the body's own sleep architecture, supporting a full night of natural, restorative sleep without the lingering sedation into the next morning.†
Sleep Peptides vs. NutraBio Sleep Capsules — Choosing Your Format
NutraBio Sleep Capsules are a melatonin-free solution for relaxation and better rest. Sleep Peptides is a more advanced formula featuring dual-release melatonin and powerful sleep peptides, designed specifically to help you fall asleep faster and support a healthy sleep-wake cycle. Choose Sleep Capsules if you specifically want to avoid melatonin; choose Sleep Peptides for the more comprehensive dual-release melatonin and peptide-based approach.†
