A smarter way to fix sleep, backed by science
Yu Sleep is a plant-based, nano-enhanced liquid sleep supplement designed for adults who struggle to fall asleep, stay asleep, or wake up feeling rested. Instead of relying on a single high dose of melatonin like most sleep pills and gummies, Yu Sleep combines 10 targeted ingredients — including GABA, L-theanine, 5-HTP, tart cherry extract, magnesium glycinate, apigenin, and lemon balm — each working on a different part of the sleep cycle.
Taken sublingually with a few drops under the tongue before bed, the liquid format is designed to absorb faster than capsules by bypassing digestion. The formula is free from synthetic sedatives and habit-forming compounds, and is manufactured in an FDA-registered, GMP-certified facility.
Most users notice results within the first few nights
Supports the restorative sleep stages tracked by wearables
Low-dose 0.9mg melatonin avoids next-day fog
Restoring your body's natural sleep pressure system
Think of your sleep pressure system like a battery that's meant to charge during the day and discharge at night. Stress, screens, and irregular schedules drain that battery without letting it recharge properly, leaving you wired at bedtime and exhausted by morning.
Yu Sleep is designed to restore that natural rhythm in stages. Within the first 30 minutes, GABA and L-theanine work to calm the nervous system and quiet a racing mind. Apigenin and lemon balm help ease physical tension, while a low, physiologically appropriate dose of melatonin (0.9mg) signals the body that it's time to shift into sleep mode. Over consistent nightly use, 5-HTP and B vitamins support the serotonin and melatonin production pathways that chronic stress can deplete over time.
Place a few drops under your tongue 30-45 minutes before bed
GABA and L-theanine begin quieting mental noise and tension within 30 minutes
Low-dose melatonin and apigenin ease your body into natural sleep mode
Tart cherry and magnesium support the deeper, restorative sleep stages
No grogginess — just consistent, uninterrupted rest night after night
GABA and L-theanine calm the nervous system within 30 minutes to help you fall asleep quicker
Magnesium glycinate and lemon balm support staying asleep through the night without 3 AM wake-ups

Physiologically appropriate low-dose melatonin avoids the heavy sedation of standard sleep aids
