What is Yu Sleep?
Yu Sleep is a liquid dietary supplement positioned by its seller for nighttime use. The current label supplied for this site lists vitamin B2, vitamin B6, melatonin and a 637 mg proprietary blend containing red tart cherry juice concentrate, magnesium glycinate, apigenin, lemon balm extract, 5-HTP, L-theanine and GABA.
The label states a serving size of 2 mL, equal to two full droppers, with approximately 30 servings per bottle. Because the blend is proprietary, the individual amounts of the ingredients inside that 637 mg blend are not disclosed on the supplied label.
What’s listed in the current Yu Sleep formula?
Melatonin · 0.9 mg
Melatonin is a hormone involved in circadian timing. The label discloses 0.9 mg per 2 mL serving. NCCIH notes that short-term use appears safe for most people, while long-term safety remains less certain.
Research overview →Vitamins B2 & B6
The label lists riboflavin 5-phosphate and pyridoxal 5-phosphate at 0.5 mg each. These nutrients have established biological roles, but their presence alone does not demonstrate a sleep benefit.
See label amounts →637 mg proprietary blend
The blend names seven ingredients but does not disclose their individual doses. That limits how directly published studies can be compared with this formula.

View Current OfferWhere should you verify Yu Sleep before buying?
For branded products sold through direct-response funnels, the most useful checks are the current package page, Supplement Facts label, shipping terms, refund policy and the final checkout total. This site links directly to the current affiliate purchase route but does not represent itself as the seller.
Important considerations
Yu Sleep contains melatonin and 5-HTP, and the label does not disclose individual amounts for the ingredients inside the proprietary blend. People who take medicines, have a medical condition, are pregnant or nursing, or are considering a supplement for a child should discuss use with a qualified healthcare professional.
NCCIH notes that melatonin may interact with medicines and that evidence for many complementary sleep approaches is limited or inconsistent. The absence of a problem in a marketing claim should not be interpreted as proof of safety for every person.
