Full body calm, woke up refreshed

Within about 30 minutes my body felt calm, and my mind at ease. Much more calm than after my usual nightly magnesium capsule. I woke up more refreshed, as my sleep was not broken like it usually was (thanks, perimenopause). The idea of having a protein shake after my evening workout, or just a typical day that helps calm me is what had drawn me to this product. The taste, simplicity of ingredients, and it being low calorie/carb are all just the icing on the cake. I will definitely be buying this again and again. Read full review

No more counting sheep

I’ve never seen a product like this: a protein powder designed to help you sleep. Let me tell you, this stuff is the truth. Night one, I could already tell it was different.It’s slow-digesting casein protein, so you stay full through the night without any stomach issues, and the calming ingredients like magnesium glycinate, tryptophan, and GABA actually work. Not melatonin. No knockout pill or groggy morning hangover.

The product I’ve been waiting for!

As someone who struggles to hit daily protein goals, I often need a shake late at night. The problem? Most powders are loaded with sugar and make it hard to get good sleep. I was skeptical at first but Sleep Protein has been a game-changer.Within just a few nights, I noticed I was falling asleep faster, staying asleep longer, and waking up rested (without the grogginess). The ingredients are clean, the taste is natural, and it mixes smoothly. It’s officially part of my nightly routine!

Finally sleeping through the night at 40!

I’m a 40-year-old mom and busy professional, and I’ve struggled with restless nights for years. I didn’t want to take melatonin anymore because it left me groggy in the morning, so I decided to try Sleep Protein. I was blown away after just a few nights. Not only am I falling asleep faster, but I’m actually staying asleep and waking up refreshed.

Strong buy!

Great taste, easy to mix, texture is smooth. 20g serving was good and added a half scoop as training load is bit higher now and the extra helped. Felt the ease of going to sleep and staying asleep to be a bit better than normal. Would recommend and defining quality. Zero stomach issues and pleasant aroma for a nighttime snack!

Great Taste and Great Results

I've been struggling with my daily protein intake and with falling asleep (and staying asleep) for more than 6 hours a night... so when I saw this product, I really had to give it a try. So far, I've been taking Sleep Protein for four days and the results have been amazing. First off, the scoop dissolves completely (even in just plain water) leaving a great-smelling and great-tasting vanilla drink that is quick and easy to drink before bedtime... and within 30-45 minutes I am completely out.

THE PERFECT PROTEIN FOR
BETTER SLEEP + MUSCLE RECOVERY

20g Milk Protein Iso (80% Casein)

Milk protein isolate contains 80% casein, offering sustained amino acid release including 500mg of additional L-Tryptophan to support overnight muscle repair, satiety, and steady recovery while you rest.

250mg Magnesium Bisglycinate 2

As magnesium bisglycinate chelate, a highly bioavailable form of magnesium that supports muscle relaxation, nerve function, and stress regulation, without causing digestive upset.

220mg L-Tryptophan

An essential amino acid that serves as a precursor to serotonin and melatonin, helping regulate mood and support the natural sleep-wake cycle.

100mg 5-HTP

Derived from tryptophan, 5-HTP boosts serotonin production, which plays a key role in promoting relaxation and setting the stage for restful sleep.

500mg GABAAccordion 3

(Gamma-Aminobutyric Acid) A naturally occurring neurotransmitter that calms nervous system activity, helping reduce mental chatter and ease the body into a more relaxed state.

250mg L-Theanine

An amino acid found in green tea, known to increase alpha brain waves—promoting a calm, focused state without drowsiness.

25mg Zinc Citrate 2

An essential mineral that helps regulate neurotransmitter activity and supports deep, uninterrupted sleep.

2000mg Inulin

This prebiotic fiber supports gut health and digestion, which plays a surprising role in neurotransmitter production and overall sleep quality.

100mg Vitamin B6

Crucial for converting tryptophan into serotonin and melatonin, helping align mood and circadian rhythms naturally.

200mg Digestive Enzymes

A clinically studied mix of digestive enzymes that enhances nutrient absorption and reduces bloating or discomfort—especially at night.

PHASE 1: NIGHTS 1-3

Night 1: The Texture & The Mix

This is a premium, slow-release Milk Protein Isolate (80% Casein) formula. It is designed to be a rich, thick, sustained-release shake that feeds your muscles overnight, not a watery supplement.

How to prepare: Mix 1 scoop with 8–10 oz of ice-cold water or your favorite nut milk in a shaker cup. Drink it 30–60 minutes before bed.

Night 2: The Melatonin-Free Difference

Don't expect a heavy, sudden drowsiness. Instead, Magnesium Bisglycinate (250mg), L-Tryptophan (220mg), 5-HTP (100mg), GABA (500mg) and L-Theanine (250mg) quietly turn down the mental noise, lowering your stress response so you can drift off naturally.

Night 3: Gut Adaptation

We built this formula to support your digestive health while you sleep. The inclusion of Inulin (2000mg), a premium prebiotic fiber, and targeted Digestive Enzymes (200mg) ensures overnight nutrient absorption. If you feel a slight shift in your digestion early on, it is completely normal as your gut microbiome optimizes.

PHASE 2: NIGHTS 4-7

Night 4: The Compound Effect

By night four, the natural sleep accelerators are building up in your system. This is where Zinc Citrate (25mg) kicks into high gear, working alongside the magnesium to help regulate your cellular sleep clock and prepare your body for more consistent sleep stages.

Night 5: The "No-Hangover" Morning

Traditional sleep aids leave you sluggish. By pairing Magnesium Bisglycinate (250mg) with Vitamin B6 (100mg), this formula helps you achieve deep, restorative sleep phases while ensuring you wake up feeling clear, alert, and energized.

Night 6: Neural Rhythm Optimization

Your neurological sleep pathways are now aligning. The steady nightly supply of L-Theanine (250mg) and GABA (500mg) establishes a predictable relaxation trigger, helping your mind transition from daytime stress to nighttime calm smoothly.

Night 7: Evaluating Week One

Take note of your sleep continuity. Are you tossing and turning less? L-Tryptophan (220mg) and 5-HTP (100mg) are steadily working behind the scenes to support natural serotonin production, leading to more stable, uninterrupted sleep cycles.

PHASE 3: NIGHTS 8-14

Nights 8-10: Metabolic & Muscle Repair

While you sleep, the 80% Casein protein continuously delivers a steady stream of amino acids to your muscles for 7 to 8 hours. By now, you should notice enhanced physical recovery, less morning stiffness, and improved daytime performance.

Night 11-14: Your New Sleep Baseline

Your body has fully adapted. Falling asleep feels effortless, your deep sleep duration is optimized, and your overnight nutrition shake has officially transitioned from a new habit into your essential nightly anchor.

Why it works: We don't use melatonin to knock you out artificially. We clear the runway with advanced amino acids, minerals, and slow-digesting proteins so your body can restore itself exactly the way nature intended. Give your system 7 to 14 nights to experience the full transformation.
