Yu Sleep Ingredients: The Full Formula

Written by the Yu Sleep Wellness Desk · Updated September 2026
Quick answer: Yu Sleep contains five named ingredients at disclosed doses — Melatonin (3mg), L-Theanine (200mg), Valerian Root (300mg), Chamomile (150mg), and GABA (100mg) — each chosen for a specific role in supporting sleep.

Melatonin (3mg)

Often called the "sleep hormone," melatonin helps regulate the body's internal clock and signals to the brain that it's time to wind down. Read more in our Melatonin deep dive.

L-Theanine (200mg)

An amino acid found in green tea, associated with promoting relaxation without sedation by supporting alpha brain wave activity. See our L-Theanine article.

Valerian Root (300mg)

Used for centuries as a traditional sleep herb, valerian root is associated with supporting GABA activity in the brain. More detail in our Valerian Root guide.

Chamomile (150mg)

Contains apigenin, a flavonoid studied for its mild calming properties and traditional association with easing anxiety before sleep. Read our Chamomile article.

GABA (100mg)

The brain's primary calming neurotransmitter, supplemental GABA is associated with quieting mental chatter and physical tension that can prevent sleep onset. See our GABA article.
