Slide 1 of 3: Canada announcement
nighttime deep sleep formula
20g of slow-release milk protein isolate, paired with 8 research-dosed calming nutrients. no melatonin. no grogginess. just a full night, done right.
available now, exclusively on iherb
calms the nervous system without melatonin.
20g protein repairs and rebuilds overnight.
eases stress before your head hits the pillow.
gentle on the stomach, easy to digest.
the base ingredient
whey digests fast and burns off within an hour or two — useful after a workout, wasted at midnight. milk protein isolate releases slowly, feeding your muscles while you're actually asleep.
illustrative amino acid availability over a night's sleep — slow-digesting casein vs. fast-digesting whey.
the formula
each dose is set at the level used in the human research behind it — nothing symbolic, nothing filler.
Delivers 20 g of protein plus an extra 500 mg of L-tryptophan for a slow, steady release through the night.
A highly absorbable form of magnesium that promotes relaxation and supports deep sleep.
The essential amino acid your body uses to support its natural sleep cycle.
Helps boost serotonin production for a calmer, quieter mind before bed.
Supports stress relief and mental quiet as you wind down.
Eases tension without drowsiness, so mornings stay clear-headed.
Supports the body's natural melatonin production and immune balance.
Helps convert tryptophan to serotonin to melatonin — your body's own sleep pathway.
your brain converts tryptophan → serotonin → melatonin every night. when serotonin is low, your own melatonin never fully switches on. sleep protein rebuilds from the start.
two direct precursors to serotonin — one sustained, one fast-acting — give your brain the raw material it’s been missing.
gaba and magnesium bisglycinate calm the nervous system — reducing the high-alert state that wakes you at 2am.
not from a bottle. not an override. your brain’s natural production — restored by feeding the pathway it always had.
slow-release protein delivers amino acids all night — feeding muscle repair during your deepest sleep phases.
the 14-night experience
sleep protein isn’t a sleeping pill. it doesn’t work in 30 minutes. it works over 14 nights because it’s rebuilding something — not chemically overriding it.
think of it like training. you don’t go to the gym once and get strong. you show up. it compounds. sleep is the same.
start tonight →sleep may feel similar. this is normal — expected even. the pathway is beginning to refuel. don’t stop here.
many people notice they’re waking less, falling back to sleep faster, or feeling calmer at bedtime. the 2am moment starts to ease.
deeper sleep. less midnight waking. muscles feeling the overnight repair. this is what sleep protein was built for.
melatonin replaces your brain’s own signal — and the longer you take it, the less your brain makes itself. sleep protein works differently.
how it works
1 scoop (32g) with 250–300ml cold water or milk, 30–60 minutes before bed.
magnesium, gaba, l-theanine, l-tryptophan & 5-htp help relax the body and quiet the mind.
zinc, magnesium and b6 work together to ease muscle tension for a full-body wind-down.
milk protein isolate gradually delivers an extra 500mg of l-tryptophan, helping you stay asleep longer.
one scoop in cold water or milk. thirty seconds with a frother and you’ve got a smooth, creamy vanilla-lavender nightcap that actually tastes good. no chalk. no grit. just calm.
creamy, lightly sweet, and ready in under a minute. the kind of night drink that makes winding down feel intentional instead of forced.

Quality You Can Trust
Recognized for bringing genuine innovation to a sleep-support category that had stayed unchanged for decades — the first protein built specifically for the night.
whether you’re winding down after a long day or recovering from training, sleep protein belongs on the nightstand — not the medicine cabinet.
what people are saying
"fell asleep fast every night and clocked at least seven and a half hours of deep, restful sleep — no grogginess the next morning."
"switched off melatonin for good. i'm falling asleep faster, staying asleep, and waking up with less muscle soreness."
"my body felt calm within about 30 minutes — more settled than my usual magnesium routine, and my sleep stayed unbroken through the night."
"no chalky aftertaste, mixes smoothly with water or coconut milk, and it digests well with zero bloating."
"far more than a sleep supplement — a full panel of protein, magnesium, zinc, tryptophan, 5-htp, gaba and theanine in one scoop."
"works as advertised — helps with sleep without melatonin, and gives me a solid source of late-day protein."
people who try it once usually make it a habit — because it actually tastes good and they wake up feeling like they slept.
who it's for
Formulated in Canada by Canadian scientists, held to Health Canada's licensing standard from day one. Our Canadian retail debut drops soon.
questions
no. sleep protein is completely melatonin-free. it supports your body’s natural sleep pathway with tryptophan, 5-htp, magnesium, zinc and b6 instead of adding exogenous melatonin.
most people report waking clear-headed. the formula is designed to support deep sleep without next-day residual sedation. if you’re sensitive to any ingredient, start with a half scoop.
mix one scoop with 250–300 ml cold water or milk 30–60 minutes before bed. consistency matters more than exact timing.
yes. it delivers 20 g of slow-release milk protein isolate overnight for recovery, is free of banned substances, and is produced in an nsf-certified facility.
vanilla lavender sky — lightly sweet, creamy, no chalky aftertaste. mixes smoothly with water or milk.
talk to a healthcare practitioner if you take medications with serotonergic activity (antidepressants, sam-e, st. john’s wort, etc.). otherwise it pairs well with most evening routines.
