On the page we reviewed, the only YU Sleep ingredient amount given is melatonin at 0.9 mg per serving. The other nine ingredients are listed without amounts, so you can't judge whether they match doses used in research. Ask for a full supplement facts panel before buying.
If you are weighing YU Sleep, one question matters before price or promises: do you know how much of each ingredient you are getting? This guide looks at YU Sleep ingredient amounts as shown on the official sales page, what is and isn't disclosed, and how to judge whether doses are meaningful.
The short version is that the page names ten ingredients but, in the text we reviewed, gives an amount for only one: melatonin at 0.9 mg per serving. That limits what anyone can say about whether the formula matches doses used in research.
We have not used this product, and we are not claiming it does or doesn't work. We are showing you how to read what is published, and what to ask for before you pay.
- Only melatonin (0.9 mg per serving) has a stated amount on the page we reviewed.
- Nine other ingredients are listed without amounts, so their doses can't be judged.
- We did not see a full supplement facts panel, serving count or bottle size in the text.
- The page cites no studies, so "clinical" claims can't be checked from it.
- Confirm everything on the full official page and the bottle label.
What YU Sleep discloses about ingredient amounts
The page describes Yu Sleep as a liquid, taken by dropper, with directions to use 2 droppers 30 minutes before bed. It lists these ingredients: red tart cherry extract, 5-HTP, vitamin B6, vitamin B2, magnesium glycinate, apigenin, lemon balm extract, L-theanine, melatonin and GABA.
The only dose given is 0.9 mg of melatonin per serving. For the rest, we have names but no milligram figures.

Is YU Sleep a proprietary blend?
People search for "yu sleep proprietary blend," and it is a fair question. We can't confirm it from the text we have, because no panel is shown. What we can say is that the practical result looks the same: you can't see most individual doses.
A proprietary blend lists a combined weight for several ingredients without breaking out each one. That makes it hard to tell whether a useful ingredient is present in a meaningful amount or a token one. Our guide to reading a sleep supplement label covers blends and other red flags in more detail.
Why amounts matter more than ingredient lists
An ingredient list tells you what is in a product. It doesn't tell you whether there is enough to matter. A formula can list a well-studied ingredient and still contain a fraction of the amount used in research.
Two things follow for you:
- A long list of recognizable names is not evidence of an effective dose.
- Stacking many ingredients at low amounts can look impressive while delivering little of each.
What "clinically meaningful" actually means
A clinically meaningful dose is one that is close to the amount used in studies that found an effect, in a form similar to what the study used. Three questions help:
- What amount did the research use, and for how long?
- Was it the same form (for example glycinate versus oxide for magnesium)?
- Were participants similar to you, such as adults with a specific sleep complaint?
For many sleep ingredients the research is mixed or small, so even a matching dose doesn't guarantee a result. Treat "clinical dose" as a way to compare, not a promise.
Ingredient by ingredient: what you can and can't judge
Melatonin: the one disclosed amount
The page states 0.9 mg per serving. That is a low dose compared with many products on the shelf, and the page contrasts itself with high-dose melatonin. Our pages on what 0.9 mg of melatonin does and low-dose side effects go deeper. Low doses can still cause vivid dreams, grogginess or interactions for some people.
One thing to confirm: whether 0.9 mg refers to the full 2-dropper serving the directions describe.
Magnesium glycinate, L-theanine and lemon balm
These have public research on sleep or relaxation, and typical amounts vary by study. Without a stated amount in YU Sleep, you can't compare. See our pages on magnesium glycinate, L-theanine and lemon balm for what research says and typical amounts.
5-HTP, GABA, apigenin, tart cherry and B vitamins
Evidence for these in sleep ranges from limited to mixed, and some have cautions. 5-HTP, for example, can interact with certain medicines, and B6 is sometimes linked by readers to vivid dreams; see can vitamin B6 cause vivid dreams?. With no amounts listed, we can't say where YU Sleep sits against any research range.
What about the "nano-enhanced" claim?
The page calls the product a "nano-enhanced sleep formula." That phrase doesn't tell you a dose, and it doesn't replace one. If absorption is meant to be improved, the amounts and the evidence still matter. We cover this in nano-enhanced sleep formulas: what the claim means.

The page says the formula supports adenosine buildup, optimizes natural melatonin release and calms the nervous system. Those are the page's claims, and it cites no studies for them. Combination evidence is thinner than single-ingredient evidence, as we discuss in do the ingredients in YU Sleep work together?.

A checklist before you buy
- Look for a full supplement facts panel on the official page or a label image.
- Confirm the serving size and that 0.9 mg melatonin applies to it.
- Check whether any ingredient amounts are grouped in a blend.
- Look for contact details so you can ask for missing amounts.
- Check for third-party testing; see third-party testing for sleep supplements.
- Read the 60-day guarantee terms. The page advertises it but the text we saw gave no conditions.
- Confirm current prices, since the page says "While Supplies Last."
Our pre-purchase checklist and buying guide cover price and refunds. The page requires a minimum 2-month package, so undisclosed amounts are a bigger commitment than a single trial bottle would be.
Downsides of the missing amounts
- You can't compare. Without doses, you can't line it up against another product, such as in our YU Sleep vs Olly Sleep comparison.
- You can't check safety limits. If you take medicines, or watch your intake of certain nutrients, amounts matter. See magnesium and medication interactions.
- You can't verify claims. The page cites no studies, so "clinical research" statements can't be traced.
Options if you want to try sleep changes first
Behavior changes cost nothing and don't depend on a label. Consistent timing, a dark and quiet room, and stimulus control are well-supported starting points. Try sleep better without buying anything and stimulus control therapy.
If you have ongoing trouble sleeping, a clinician can look for causes a supplement won't address.
Next steps
Start by looking for the full supplement facts panel and confirming the melatonin serving. Then compare with YU Sleep vs alternatives or best liquid sleep aids and drops. For the wider picture, read YU Sleep reviews, complaints and trust.
Frequently asked questions
Does YU Sleep disclose ingredient amounts?
Only partly. The official page we reviewed states 0.9 mg of melatonin per serving. The other listed ingredients appear without amounts, and the text we saw did not include a full supplement facts panel. Check the full page and the bottle label before buying.
Is YU Sleep a proprietary blend?
We can't confirm that. The text we reviewed lists ten ingredients but shows no full supplement facts panel, so we can't say whether amounts are grouped in a blend. The practical effect is similar: you can't see most individual doses.
Are YU Sleep doses clinically meaningful?
For most ingredients, nobody can tell from the page, because no amounts are given. Melatonin at 0.9 mg is a low dose. The page also cites no studies, so claims of clinical backing can't be checked.
How much melatonin is in YU Sleep?
The page states 0.9 mg of melatonin per serving. The directions say to take 2 droppers 30 minutes before bed. It's unclear from the text we saw whether 0.9 mg refers to the full 2-dropper serving, so confirm that on the label.
What should I look for on a sleep supplement facts panel?
Look for the serving size, an amount for every active ingredient, the form of each (for example magnesium glycinate rather than just magnesium), and any blend totals. Third-party testing marks such as USP or NSF are also worth checking.
Can I ask YU Sleep for its full ingredient amounts?
You can try. The page we reviewed names no company or support contact, so look for contact details on the full official page or at checkout. If you can't get a full panel, that's a reasonable reason to wait or choose a product that discloses amounts.
Is low-dose melatonin safer than high-dose?
Lower doses are generally associated with fewer next-day effects like grogginess, but low doses can still cause side effects and interact with some medicines. Talk to a pharmacist or doctor if you take medication or have a health condition.
