Optimize Sleep

YAWN is a nootropic blend with components optimized for each of the three phases of sleep: falling asleep, improving quality of sleep, and feeling refreshed upon waking up. Sufficient, high-quality sleep is widely agreed to be the single most important activity you can do to optimize cognition and your mental state in the near-term.

YAWN is designed to be taken as needed, and does not need to be taken daily like KADO-3 or RISE.

Each bottle of YAWN contains 10 capsules.


Take one capsule of YAWN with a glass of water, one hour before bedtime.

For a more pronounced and immediate effect, YAWN can be taken sublingually as follows. Open the capsule carefully, by holding it vertically and pulling the two halves of the capsule apart. Pour the contents under your tongue and allow to sit for 30 seconds. Then follow by drinking water. YAWN has a mild and slightly sweet taste.

Nootropic Ingredients

The ingredients in YAWN are selected specifically to help you go to sleep faster, sink into a deep sleep more reliably, and wake up feeling refreshed and rejuvenated. The amount, concentration, and ratio of each ingredient are specifically drawn from double-blind, peer-reviewed journal studies that statistically significantly demonstrate each compound's efficacy.

YAWN is contained within a vegetable cellulose capsule, which is vegan, flavorless, and allergen-free.


Glycine has been shown in multiple trials to improve both subjective and objective measures of sleep quality and improves day-after cognitive performance.


Magnesium is a general relaxant and critical for healthy nervous system function. Magnesium deficiency, at least to a minor degree, appears to affect a large percentage of adults.


L-theanine has been shown to reduce stress and anxiety as measured by cortisol and other biomarkers.


Melatonin acts strongly to promote your desired sleep-wake cycle by reducing the time it takes to fall asleep.

Frequently Asked Questions

Can I take YAWN with other Nootrobox products?

Yes. All Nootrobox products are designed to be compatible and work together as a system.

Is YAWN vegan / gluten-free / allergen-free?

YAWN is vegan, gluten-free, and free of all major allergens.

What else can I do to improve sleep quality?

In order to best optimize your sleep, avoid any caffeine at least 6 hours before going to sleep (including SPRINT, GO CUBES, coffee, energy drinks, etc.).

Turn down the lights at least an hour before going to sleep. Especially avoid harsh artificial light from screens as they generate blue wavelength light, which depresses natural melatonin levels and disrupts a natural circadian rhythm. Consider using software like Flux to modulate your computer screen to warmer tones. White noise generators, natural soundtracks (like falling rain), and relaxing music can all help to induce sleep as well.

Eliminating 100% of noise and light while sleeping is important, and you may consider getting blackout curtains or a sleeping mask to block sunrise from disrupting the tail end of your sleep.

Diet and exercise can also improve sleep latency and efficiency. Getting exercise on a daily basis (even if just going for walk) helps to release energy and set your body up for a restful night. Keeping a modest and healthy diet, and avoiding food (especially sweets) before bedtime, are ways of encouraging a healthy night's rest.

How will I feel after taking YAWN?

YAWN will reduce anxiety and induce sleepiness within 30 - 60 minutes.

Should I take YAWN every day?

The effects of YAWN are acute and immediate. YAWN does not require habitual daily use in order to realize a benefit.

YAWN is ideal for reducing sleep latency on especially restless nights. Many users also find it useful in combating jetlag and inducing sleep during long-distance trips (plane, bus, etc.).

What are the three components of high quality sleep?

The first component of high quality sleep is getting to sleep (sleep latency). Any minute that you spend trying to fall asleep, is one minute that you're not actually sleeping.

The second component is the actual quality and depth of the sleeping process (sleep efficiency). Not all sleep is equal. A complete sleep cycle (each of which is comprised of 5 distinct stages) typically takes about 90 minutes and the rule of thumb is that you need 4-5 full sleep cycles. A sleep cycle is comprised of four stages of non-REM sleep followed by REM, or dreaming, sleep. REM sleep is the time when most dreams occur. Recent theories suggest that REM is correlated with memory and learning.

The third component is being refreshed upon waking up. From a functional perspective, waking up refreshed and ready to take on the new day is the ideal after a night's sleep. Reducing grogginess and increasing energy upon waking in the morning is an important part of an optimized sleep nootropic like YAWN.


Yep, YAWN = darkhorse. Combined with meditation, my restfulness has compounded with daily use.

Yawn rocks, makes a difference in my life and productivity, sleep is underrated, nano repair ops @ night

Enjoying my first days using the STACK. YAWN sleep was awesome.

Dam #Yawn hit me hard. Good thing because I can't get a lot of sleep because of my job. At least I wake up refreshed



March 2017. Reduced melatonin content from 1.5 mg to 300 mcg. Increased glycine content from 450 mg to 500 mg. Changed magnesium source from magnesium citrate (200 mg) to magnesium glycinate (250 mg) to add additional glycine content.


Launched July 2014.
