With these 7 synergistic ingredients,
Yu Sleep doesn’t just knock you out—it restores your body’s natural sleep architecture, balances brain chemistry, and promotes consistent, rejuvenating rest.
1. Red Tart Cherry Extract
Red Tart Cherries are naturally rich in melatonin, the hormone responsible for regulating your body’s internal sleep-wake cycle. This extract helps your body signal when it’s time to wind down, making it easier to fall asleep. It also supports longer, uninterrupted sleep by reducing nighttime awakenings, ensuring you wake up refreshed and energized.
2. 5-HTP (5-Hydroxytryptophan)
5-HTP is a natural compound that acts as a direct precursor to serotonin, the neurotransmitter that influences mood, relaxation, and sleep quality. By boosting serotonin, 5-HTP helps reduce anxiety and promotes calmness before bedtime. It also naturally enhances melatonin production, making it easier to achieve deeper, more restorative rest.
3. Vitamins B6 & B12
These essential B vitamins play a crucial role in supporting your nervous system, brain health, and sleep cycle. Vitamin B6 assists in the conversion of tryptophan to serotonin and melatonin, while Vitamin B12 helps regulate circadian rhythm—the internal clock that governs when you feel awake and when you feel sleepy. Together, they improve sleep quality while also enhancing daytime energy and cognitive function.
4. L-Theanine
L-Theanine is an amino acid found in green tea leaves, known for its natural calming properties. It increases alpha brain waves, which are linked to relaxation and mental clarity. L-Theanine helps quiet racing thoughts, reduce stress, and ease tension, creating the perfect mental state for falling asleep peacefully. Unlike sedatives, it promotes relaxation without drowsiness.
5. Melatonin
Melatonin is a naturally occurring hormone that tells your body when it’s time to sleep. Supplementing with melatonin helps shorten the time it takes to fall asleep while improving sleep duration and quality. Yu Sleep uses a gentle, balanced dose of melatonin that supports your natural production without overwhelming your system—helping you wake up refreshed instead of groggy.
6. GABA (Gamma-Aminobutyric Acid)
GABA is one of the brain’s most important calming neurotransmitters. Its role is to slow down overactive brain signals, reduce nervous system tension, and promote relaxation. By lowering stress levels and quieting mental chatter, GABA helps your body and mind prepare for deep, restorative sleep, keeping you asleep longer throughout the night.
7. Vitamin B Complex Support (B6 + B12 synergy)
While highlighted separately, the combined effect of B6 and B12 is worth noting. Together, they not only regulate sleep-related neurotransmitters but also support energy metabolism. This means you not only fall asleep better but also wake up feeling mentally sharp, emotionally balanced, and physically energized.
