Is yusleeps-us.com the official Yu Sleep website?

How is Yu Sleep used?
Two droppers (2mL) about 30 minutes before bedtime, used consistently each night, per product directions.
Does Yu Sleep cure insomnia?
No. It's not marketed or evaluated as a treatment for insomnia or any diagnosed sleep disorder. This statement has not been evaluated by the FDA. See a healthcare provider for persistent sleep problems.
Will it cause next-day grogginess?
The manufacturer states the low melatonin dose is designed to avoid grogginess. That's a product claim, not independently tested by this site.
What does research say about the ingredients?
It varies a lot by ingredient — from reasonably supported (melatonin for circadian timing) to disputed (GABA's oral bioavailability). Full evidence breakdown →
