Yu Sleep is aimed at adults who fall asleep without much trouble but come awake somewhere around 3am and then lie there for an hour or more. It is a liquid supplement taken as two droppers before bed, sold through ClickBank, and its formula leans on a deliberately small melatonin dose rather than the 3-10mg found in most drugstore sleep aids. This review covers what is actually on the label, what the vendor claims but has not shown, and whether the price holds up.
Our verdict
The restraint on melatonin is a genuine point in its favour, and the rest of the label is a sensible if unremarkable sleep stack. What we cannot get past is that nobody will say who makes it — no manufacturer, no company registration, no third-party testing results you can look up. At $69 for a single month plus shipping, that is a premium price to pay a company that has not identified itself.
Worth it if
You fall asleep fine but wake around 3am, and you want a low melatonin dose rather than the 3-10mg on supermarket shelves
You would rather take a liquid at bedtime than swallow capsules
You want one bottle instead of buying magnesium glycinate, L-theanine and apigenin separately
You are willing to commit to six months, where the cost falls to $39 a month with shipping included
Look elsewhere if
You want to know who manufactures what you swallow — no maker, company registration or third-party testing is published
You take prescription medication: 5-HTP interacts with several common ones, so this needs a doctor's opinion first
You are buying on the '99% absorption' and 4.9-star claims — both are the vendor's own figures, offered without an independent source
Plain low-dose melatonin would do, since on its own it costs a fraction of this
What stands out
Melatonin is dosed at 0.9mg per serving, well below the 3-10mg typical of supermarket sleep aids, and the lower end of that range is the better-studied one for sleep-onset timing without next-day grogginess.
The full ingredient list is published up front: red tart cherry extract, 5-HTP, vitamins B6 and B2, magnesium glycinate, apigenin, lemon balm extract, L-theanine, GABA and melatonin, so you can check it against anything you already take.
Liquid dropper format rather than capsules or tablets, which suits anyone who would rather not swallow pills at bedtime.
A 60-day money-back guarantee, and the six-month order brings the cost down to $39 a month with shipping included.

Our full review
The most defensible thing about Yu Sleep is its restraint on melatonin. At 0.9mg per serving it sits well under the 3-10mg on most supermarket shelves, and the lower doses are the ones better supported in the research for sleep-onset timing without the fogged feeling some people report the following morning. The rest of the label — magnesium glycinate, L-theanine, apigenin, lemon balm, GABA, 5-HTP — is a fairly conventional sleep stack; nothing on it is exotic, and most of it can be bought separately for less. What you are paying for is the combination, the liquid format and not having to assemble it yourself.
Transparency is where it falls down, and that is the main reason to hesitate. The product is fronted by a 'Dr. Collins' with no published manufacturer, no company registration and no third-party testing results you can look up, which for something you swallow every night is a real gap rather than a nitpick. The vendor also claims 99% absorption via 'advanced nano-technology' and a 4.9-star average from more than 36,000 reviews; both are the vendor's own figures, offered without an independent source, and should be read as marketing rather than evidence. Add $69 for a single month with shipping on top, and you are paying a premium price to a company that has not said who it is.

Frequently asked questions
How is this different from the melatonin I can buy at the supermarket?
Mainly the dose and the format. Yu Sleep uses 0.9mg of melatonin per serving against the 3-10mg common in drugstore tablets, and delivers it as a liquid alongside nine other ingredients including magnesium glycinate, L-theanine and lemon balm. Whether that combination suits you better than plain low-dose melatonin is something only trying it will tell you, and low-dose melatonin on its own costs considerably less.
What does it cost, and what happens if it does not work for me?
At the time of writing, one month is $69 plus shipping, three months is $177 ($59 a month) and six months is $234 ($39 a month with free shipping). The vendor offers a 60-day money-back guarantee. Read the current refund terms on the order page before buying, since the conditions and who pays return postage are the details that decide how useful a guarantee actually is.
Is it safe for me to take?
That is not something a review can answer for you. If you take any medication, are pregnant or breastfeeding, or have a diagnosed sleep disorder such as sleep apnoea or restless legs, talk to a doctor before starting this or any sleep supplement — 5-HTP in particular interacts with several common prescriptions. Persistent 3am waking is also worth raising with a doctor in its own right.
