Optimize Sleep.


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.

Sleep is your brain’s recovery mode.

YAWN helps you fall asleep quickly and effectively.

YAWN combines the sleep inducing effects of melatonin and glycine, into one super-sleep stack.

In 19 studies of melatonin, participants fell asleep 7.06 minutes faster on average1,2,3.

REM Sleep Parameters

Designed to help you fall asleep faster and feel more rested.

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. Sleep is when memory consolidation, recovery, and neuroprotective processes activate. You should optimize those processes.

Start the day refreshed.

YAWN improves your sleep and enhances your cognition the day after a restful night of sleep

Self-Reported Sleep Quality

In one study, ingesting glycine before sleep improved 'fatigue', 'liveliness and peppiness', and 'clear-headedness' on the St. Mary's Hospital Sleep Questionnaire and Space-Aeromedicine Fatigue Checklist5.

Self Reported Fatigue

Participants forced to sleep 25% less than usual for three nights showed 50% reduction in subjective fatigue after taking glycine at bedtime on the fourth night5.

Produced in the pineal gland of the brain and promotes sleep and regulates the circadian rhythm (sleep-wake cycle)10

When traveling across time zones, melatonin supplementation at or near the time you would sleep at your final destination has been shown to be a powerful method to pre-set your sleep-wake cycle and reduce jet lag11

Magnesium Glycinate

250 mg

Can improve sleep quality and reduce stress

The glycinate form adds bioavailability of magnesium and additional glycine content12

Magnesium deficiency is common in the United States, with an estimated 68% of the population not meeting the FDA recommended daily intake of magnesium3,13,14


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.

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.
