The short answer: Yu Sleep is a liquid sleep supplement combining a low 0.9 mg dose of melatonin with nine other ingredients, including magnesium, L-theanine, tart cherry and 5-HTP. The melatonin dose is sensible and disclosed; the rest of the blend has limited evidence and hides its amounts. It may help some people fall asleep a little faster in the short term. It's not suitable if you take antidepressants or other serotonin-affecting medicines, because of the 5-HTP, and it isn't a fix for long-term insomnia. Prices start at $49 a bottle in the largest bundle, with a 60-day guarantee that comes with strings attached.
Sleep problems are common in midlife, and they often get worse around menopause, when night sweats and hormone changes break up sleep. Yu Sleep is one of the best-selling sleep products on ClickBank. Here's what's in it and what you can reasonably expect.
Directions for use
- Melatonin 0.9 mg: a low, sensible dose. NCCIH says melatonin may help you fall asleep a little faster; long-term safety isn't established.
- Proprietary blend (637 mg): tart cherry, magnesium, apigenin, lemon balm, 5-HTP, L-theanine and GABA, with no individual amounts.
- 5-HTP raises serotonin: don't combine with antidepressants without your doctor.
- Price: $49 to $69 a bottle depending on the bundle, at the time of writing.
- Refund: 60 days, but you pay return shipping and must send back all bottles.
What's in Yu Sleep
According to the published label, each 2 mL serving contains:
| Ingredient | Amount |
|---|---|
| Melatonin | 0.9 mg |
| Vitamin B6 (as pyridoxal 5-phosphate) | 0.5 mg |
| Vitamin B2 (as riboflavin 5-phosphate) | 0.5 mg |
| Proprietary blend: tart cherry juice concentrate, magnesium glycinate, apigenin, lemon balm extract, 5-HTP, L-theanine, GABA | 637 mg total |
It's a flavoured liquid, taken about 30 minutes before bed. The blend is sweetened with erythritol and invert syrup.
What the evidence says
Melatonin. NCCIH's review finds melatonin may help people fall asleep slightly faster and is useful for jet lag and shift work. Two clinical guidelines recommend against it for chronic insomnia. It appears relatively safe short term, but long-term safety isn't established. A low dose like 0.9 mg is a point in Yu Sleep's favour: many products contain 5 to 10 mg.
5-HTP. NCCIH notes there's very limited data on 5-HTP for insomnia. It's included because the body turns it into serotonin, which it then uses to make melatonin.
Magnesium. Research on magnesium for sleep is very limited. It may help older adults fall asleep a little faster. The amount in a 637 mg blend shared with six other ingredients is likely small.
L-theanine, lemon balm, apigenin, tart cherry, GABA. Each has some small or early studies on relaxation or sleep, but none has strong evidence, and the doses here aren't disclosed.
The seller's claims. The official site says most people start sleeping better within 3 to 7 days. There are no published trials of Yu Sleep itself to confirm that.
Who it may suit
- Adults with occasional trouble falling asleep, for example after travel, during a stressful stretch, or during menopause, who want a low-dose melatonin product
- People who prefer a liquid to capsules or gummies
Who should skip it
- Anyone taking antidepressants (SSRIs, SNRIs, MAOIs), triptans for migraine, tramadol or other serotonin-affecting medicines: 5-HTP combined with these can cause serotonin syndrome
- Pregnant or breastfeeding women
- People taking blood thinners, blood-pressure medicines, diabetes medicines, sedatives or immunosuppressants without asking their doctor (melatonin can interact with these)
- Anyone with long-term insomnia, snoring with pauses in breathing, or restless legs: these need a medical assessment
- Children (keep it out of reach: the CDC has reported thousands of emergency visits from children swallowing melatonin)
Price, guarantee and where to buy

Try these first (they're free)
- Keep a regular wake-up time, even at weekends.
- Keep the bedroom cool and dark, which also helps with night sweats.
- Limit caffeine after midday and alcohol in the evening.
- Wind down for 30 minutes before bed. Our legs-up-the-wall reset is one easy option.
- If sleep problems last more than a few weeks, ask your doctor about CBT for insomnia (CBT-I), the most effective long-term treatment.
A note of caution
Don't drive or use machinery until you know how a sleep supplement affects you, and don't combine it with alcohol or other sleep aids. If you take any regular medication, check with your pharmacist before starting Yu Sleep. Stop taking it and seek medical help if you develop agitation, a fast heartbeat, fever, muscle twitching or confusion.
Verdict
Yu Sleep gets the melatonin dose right and discloses it, which puts it ahead of many sleep products. The rest of the blend is a mix of lightly studied ingredients in undisclosed amounts, and the 5-HTP rules it out for anyone on antidepressants. For occasional sleeplessness in someone not on interacting medicines, it's a reasonable short-term try, especially alongside better sleep habits. For ongoing insomnia, see your doctor.
