3 g
Glycine
A small crossover trial at this dose reported improvements in subjective sleep quality, sleep efficiency, sleep onset, and next-day sleepiness.
Human sleep study
The world's first
chocolate built for
recovery and
sleep support.
Scientifically Engineered
for Sleep
Cocoa solids naturally carry caffeine and theobromine. CH1 shifts the architecture toward cocoa butter and naturally sweet carob, then uses a restrained amount of cocoa powder for depth.
The result is chocolate designed to support overnight recovery. Slow-digesting micellar casein supplies amino acids while you sleep, supported by glycine and the wider functional formula. It is chocolate designed to work with your body while you sleep, rather than keep you awake.
SIX FUNCTIONAL COMPONENTS
The formula is anchored to published research, but the strength and directness of that evidence varies by ingredient. The labels below show the difference clearly.
300 mg
L-Theanine
Studied for its relationship with stress, relaxation, and sleep quality. A four-week trial used 200 mg daily, so it is supportive evidence rather than a direct test of CH1.
Human evidence, nearby dose100 mg elemental
Magnesium bisglycinate
Magnesium contributes to normal nervous system function. Sleep trials have used other forms or higher doses, with results ranging from modest to positive.
Human evidence, different doses2 g
Tart cherry
Tart cherry naturally contains melatonin and polyphenols. A small juice-concentrate trial reported higher urinary melatonin and improved sleep duration and efficiency.
Human evidence, different format2 g
Reishi
Traditionally used for calm and balance. Sleep-supporting findings are currently led by animal research, with limited randomised human evidence.
Preclinical evidence10 g
Micellar casein
A slow-digesting milk protein. Pre-sleep research at higher doses shows amino acids are absorbed overnight and can support post-exercise protein synthesis.
Human recovery evidence, higher dose
THE ARCHITECTURE
Pure cocoa butter supplies the texture. Carob does much of the work usually asked of cocoa solids, without caffeine or theobromine. Alkalised cocoa powder brings back the familiar chocolate depth.
- Cocoa butter for melt and finish
- Carob for body and natural sweetness
- Cocoa powder for a measured chocolate note
WHY GLYCINE
Sleep support.
Structural role.
3 g in CH1.
Approximately 30% in collagen.
CH1 contains 3 g of glycine, matching the amount used in a small human sleep study. Glycine appears at every third position in collagen's repeating Gly-X-Y sequence, which means approximately 30% of collagen's amino acid residues are glycine. Collagen is a structural protein found in cartilage, tendons, ligaments, skin, and bone.
3 CHAINS
1 TRIPLE HELIX
Glycine contributes to collagen structure, but consuming it does not prove joint repair or treatment of damaged tissue.
The Literature
Each source is paired with the limitation that matters most. Open a study to see the design, the relevance to CH1, and where direct product testing is still needed.
01Glycine and sleep+
Small crossover study in volunteers with unsatisfactory sleep, using 3 g before bed and polysomnography.
Evidence note: Closest match to CH1's lead ingredient and target dose.
Open source ↗Yamadera et al., Sleep and Biological Rhythms, 200702L-theanine, stress, and sleep+
Randomised placebo-controlled trial in 30 healthy adults using 200 mg daily for four weeks.
Evidence note: Supports the pathway, but does not test the complete bar or its 300 mg dose.
Open source ↗Hidese et al., Nutrients, 201903Magnesium and insomnia+
Double-blind placebo-controlled trial in 46 older adults with insomnia using 500 mg magnesium oxide.
Evidence note: Different population, form, and dose from CH1.
Open source ↗Abbasi et al., Journal of Research in Medical Sciences, 201204Tart cherry and melatonin+
Randomised crossover trial in 20 adults using tart cherry juice concentrate for seven days.
Evidence note: Different product format and no direct dose equivalence to 2 g powder.
Open source ↗Howatson et al., European Journal of Nutrition, 201205Reishi and sleep time+
Ganoderma lucidum extract increased sleep time in a rat study measured with EEG and EMG.
Evidence note: Preclinical evidence only. Human sleep trials remain limited.
Open source ↗Cui et al., Journal of Ethnopharmacology, 201206Casein and overnight recovery+
Sixteen healthy young men consumed 40 g casein before sleep after evening exercise.
Evidence note: Establishes overnight digestion and amino acid use at a higher dose than CH1.
