General Questions

What is Yu Sleep supplement?

Yu Sleep is a natural, nano-enhanced liquid sleep supplement that helps you fall asleep faster, stay asleep all night, and wake up refreshed. It contains 10 clinically studied ingredients.

How does Yu Sleep supplement work?

Unlike typical sleep aids that just sedate you, Yu Sleep targets your sleep pressure system — the biological mechanism that makes you naturally tired at night. It supports natural melatonin production, calms your nervous system, and reduces stress hormones.

Is Yu Sleep supplement safe?

Yes. Yu Sleep is made from natural, plant-based ingredients with no synthetic fillers. It is manufactured in a GMP-certified facility. Consult your healthcare provider if you are pregnant, nursing, or on medications.

Is Yu Sleep supplement habit-forming?

Ingredients and Formula

What ingredients are in Yu Sleep supplement?

Yu Sleep contains 10 ingredients: Red Tart Cherry Extract, 5-HTP, Vitamin B6, Vitamin B2, Magnesium Glycinate, Apigenin, Lemon Balm Extract, L-Theanine, Melatonin (0.9mg), and GABA. For a complete breakdown of each ingredient and the science behind it, see our Yu Sleep ingredients guide.

Why does Yu Sleep only have 0.9mg of melatonin?

Most supplements use 3-10mg, which is excessive. Yu Sleep uses 0.9mg because it works synergistically with 9 other supporting ingredients. Research shows lower doses combined with other ingredients are just as effective. See our Yu Sleep vs melatonin comparison for a detailed breakdown.
