Yu Sleep Ingredients: The Full Formula
Yu Sleep combines nine research-backed sleep ingredients in a fast-absorbing liquid. Here is exactly what is inside, what each ingredient does, and the safety notes worth knowing before you start.
Every Ingredient, Explained
Each ingredient is included at a purposeful dose to support natural, restful sleep.
Red Tart Cherry
A natural source of melatonin and antioxidants that supports the body’s own sleep-wake rhythm and helps ease you toward rest.
5-HTP
A precursor to serotonin and melatonin that supports mood and the transition into sleep. Sourced naturally to help the body build its own calming neurotransmitters.
Note: If you take an SSRI or other antidepressant, talk to your doctor before using — see the safety warning below.
Magnesium Glycinate
A highly absorbable form of magnesium that supports muscle relaxation and a calm nervous system, helping to quiet physical tension before bed.
Apigenin
A natural flavonoid found in chamomile that binds to calming receptors in the brain to promote relaxation and reduce bedtime restlessness.
Lemon Balm
A traditional calming herb used for centuries to ease anxiousness and support a peaceful state of mind ahead of sleep.
L-Theanine
An amino acid from green tea that promotes relaxation and calm focus without sedation, helping to quiet a racing mind.
Melatonin (0.9mg)
A deliberately low, physiological dose that gently signals your body it is time to sleep — without the grogginess of high-dose melatonin products.
GABA
A key inhibitory neurotransmitter that helps calm nervous system activity, supporting the shift from wakefulness into restful sleep.
Vitamins B6 + B2
Support the body’s natural conversion of nutrients into calming neurotransmitters like serotonin and melatonin, helping the whole formula work efficiently.
The Nano-Enhancement Advantage
Yu Sleep uses a nano-enhanced liquid delivery system. The active compounds are reduced to particles smaller than 100 nanometers (sub-100nm), which the body can absorb far more readily than a standard capsule.
In practice this is designed to deliver 2-3x faster absorption than traditional pills, so the calming ingredients can begin working within roughly 30 minutes of your two evening droppers.
Clean Label Standards
Safety Warning: 5-HTP + SSRIs
Yu Sleep contains 5-HTP, which raises serotonin. Combining 5-HTP with SSRIs, SNRIs, MAOIs, or other serotonergic medications can, in rare cases, contribute to serotonin syndrome — a potentially serious condition. If you take any antidepressant or serotonin-affecting medication, do not use Yu Sleep without first consulting your doctor or pharmacist.
Backed by Published Research
The individual ingredients in Yu Sleep — including tart cherry, 5-HTP, magnesium glycinate, apigenin, L-theanine, and GABA — are supported by more than 20 published studies indexed on PubMed examining their roles in sleep quality, relaxation, and neurotransmitter support. As always, results from single- ingredient studies may differ from a combined formula.
