What is Yu Sleep, and who makes it?
Yu Sleep is a liquid sleep supplement in an amber dropper bottle. Instead of swallowing capsules, you squeeze two droppers into your mouth about half an hour before bed. The brand describes it as a delicious, all-natural formula designed to help you fall asleep faster, stay asleep all night without the 3 AM wake-ups and wake up truly refreshed.
The label lists ten sleep ingredients: red tart cherry juice concentrate, magnesium glycinate, apigenin, lemon balm extract, 5-HTP, L-theanine and GABA in a 637 mg blend, plus vitamins B6 and B2 and 0.9 mg of melatonin per serving. That melatonin amount is deliberately low. The brand positions Yu Sleep as the alternative to high-dose melatonin products and says it works with your body's natural rhythm so you don't wake up groggy.
Each 2 fl oz (60 ml) bottle holds about 30 servings, a month of nights. Yu Sleep is sold through its official store in 2-, 3- and 6-month supply packs, and the two larger packs come with three free bonuses: a set of 11 bedtime stories as eBook and audio, an evening-rituals eBook and a guide to bedtime snacks.
It's sold by BuyGoods (Wilmington, Delaware, USA). The sales page names BuyGoods, a Delaware corporation at 1201 N Orange Street, Suite #7223, Wilmington, DE 19801, as the retailer of Yu Sleep, and the order is paid on BuyGoods' secure checkout. Yu Sleep's own support answers at support@yu-sleep.com and by phone at +1 302-404-2568, and the refund policy gives the brand's US return address: Yu Sleep, 19655 E 35th Drive, Suite 100, Aurora, CO 80011.

Ingredients, one by one
The brand doesn't publish the dose of each ingredient per serving. We list what each one is and what research says about it in general.
Six of the ten ingredients in Yu Sleep
The sales page pictures each ingredient in the formula. These are six of them; what each one does is the brand's description, listed one by one below.
Tart cherry
Magnesium glycinate
L-theanine
Lemon balm
Apigenin
Melatonin, 0.9 mg
Images from the brand's own ingredient section. The label gives exact amounts for melatonin and the two B vitamins and one total, 637 mg, for the blend.
Melatonin (0.9 mg)
Supplement facts label and sales pageThe body's own "time for bed" signal. The brand uses a low 0.9 mg per serving and says it tells your body it's time to rest, shortens the time it takes to fall asleep and supports longer, higher-quality sleep.
What research says: A meta-analysis of 19 placebo-controlled trials with 1,683 people found that melatonin shortened the time to fall asleep, added to total sleep time and improved overall sleep quality, and that the effect held with continued use. Source
Red tart cherry juice concentrate
Supplement facts label and sales pageThe cherry the formula is built around and the first item in the blend. The brand says it helps regulate the sleep-wake cycle, reduce nighttime awakenings and increase total sleep time.
Magnesium glycinate
Supplement facts label and sales pageMagnesium bound to the amino acid glycine. The brand says it promotes the restorative stages of sleep.
What research says: A systematic review and meta-analysis of three randomized trials in 151 older adults found people fell asleep about 17 minutes sooner with magnesium than with placebo; the authors note the trials were small. Source
L-theanine
Supplement facts label and sales pageAn amino acid found in tea. The brand says it promotes the alpha brain waves linked with calm, focused relaxation and helps quiet racing thoughts.
What research says: A 2025 systematic review and meta-analysis of 19 randomized trials with 897 participants found L-theanine improved how quickly people felt they fell asleep, their daytime function and their overall sleep quality score. Source
Lemon balm extract
Supplement facts label and sales pageA calming herb from the mint family. The brand says it lowers cortisol, the stress hormone it links to middle-of-the-night wake-ups.
What research says: A systematic review and meta-analysis of clinical trials found lemon balm improved anxiety and mood scores compared with placebo, without serious side effects; the authors ask for more large trials. Source
Apigenin
Supplement facts label and sales pageA plant compound best known from chamomile. The brand calls it "nature's gentle sedative" and says it helps shorten the time it takes to fall asleep, with less tossing and turning.
5-HTP (Griffonia seed extract)
Supplement facts label and sales pageA building block the body uses to make serotonin. The brand says it supports serotonin production, lifts mood and promotes relaxation.
GABA
Supplement facts label and sales pageA calming messenger of the nervous system. The brand says it quiets overactive brain activity and helps the body unwind into deep sleep.
Vitamin B6 (0.5 mg) and vitamin B2 (0.5 mg)
Supplement facts label and sales pageTwo B vitamins in their active forms, pyridoxal 5-phosphate and riboflavin 5-phosphate. The brand says they work together to regulate the body clock and support natural melatonin production.
Does Yu Sleep work?
The brand builds Yu Sleep around what it calls the brain's sleep pressure system, the natural drive that makes you tired at night. According to the brand, the formula supports that system in three ways: it supports adenosine, which it describes as the body's sleep fuel, it optimizes the natural release of melatonin, and it calms the nervous system so you can fall asleep easier and stay asleep longer.
Each ingredient has a job in that plan. The brand says tart cherry helps regulate the sleep-wake cycle, magnesium glycinate promotes the restorative stages of sleep, apigenin and L-theanine settle the mind, lemon balm takes the edge off the stress hormone it links to 3 AM wake-ups, and a low 0.9 mg of melatonin tells the body it's time to rest. Several of these have been studied on their own: published meta-analyses report that melatonin shortens the time it takes to fall asleep and improves sleep quality, and that L-theanine improves people's own ratings of their sleep.
On timing, the brand says most people start sleeping better within 3 to 7 days: falling asleep easier in the first nights, sleeping through in the first week and waking up refreshed within two weeks. It describes a full reset as a 3-to-6-month project, which is why it sells multi-month packs. Its refund page adds that most people report the real change between weeks two and four, and asks for 21 nights in a row before you judge it.
To get the most from it, follow the routine the brand lays out. Keep the bottle on your bedside table so you never skip a night. About 30 minutes before bed, squeeze two full droppers into your mouth, under the tongue if you can, hold for a slow count of thirty, then swallow. Take it every night; if you miss one, carry on the next. Dim the lights, put the phone down and let one of the bonus bedtime stories play while it settles in.

How the refund really works
The sales page promises 60 days to test Yu Sleep and your money back if you don't love it. The store's written refund policy sets the steps: within 60 days of your purchase, email support@yu-sleep.com with your full name, email address, BuyGoods invoice and order number, and say exactly what you're returning. Mail the package to Yu Sleep, 19655 E 35th Drive, Suite 100, Aurora, CO 80011, with your order number on a note inside, then send support the tracking number; the policy says the refund is issued as soon as they have it, and that the date you post it is the one that counts. Shipping and handling aren't refundable, so the policy says refunds come to around 85% of the purchase price, and return postage is yours. The guarantee works once per customer: a second order after a refund isn't covered. The brand also asks you to give it 21 nights in a row before you decide, which fits comfortably inside the 60 days.
Before you pay: The three packs on the US checkout we saw on November 14, 2026 were one-time purchases with no recurring charge on the screen. If your checkout shows a "Subscribe & Save" box, leave it unchecked to keep the order one-time.
Is Yu Sleep legit or a scam?
Yu Sleep is sold through an established US retailer. The sales page names BuyGoods, a Delaware corporation, as the retailer, and your payment goes through BuyGoods' secure checkout with card, PayPal, Apple Pay or Google Pay. You get an invoice by email, and that invoice is what support asks for if you ever want a refund.
Support is easy to reach: the store lists an email address, support@yu-sleep.com, a US phone number, +1 302-404-2568, and a US return address in Aurora, Colorado. Orders ship within 24 hours according to the store's FAQ, the tracking link arrives by email within three business days, and US delivery usually takes 5 to 7 business days.
The label is open about the essentials. It prints the serving size, the servings per bottle and the exact amounts of melatonin and both B vitamins, and it names every ingredient in the blend. The guarantee is written down too: 60 days from purchase, with the steps listed in the refund policy.
Three practical tips make the purchase smooth. Pick your pack with the nightly routine in mind, since the smallest order is two bottles. Read the order summary before you pay, where the total and shipping are shown. And save the BuyGoods invoice email, so everything you'd need for the guarantee is in one place.
Where to buy the original Yu Sleep
Order from the official Yu Sleep store. That's where the pack prices above, free shipping on the 3-month and 6-month packs, the three free bonuses and the 60-day guarantee apply.
The refund policy asks for your BuyGoods invoice, which only an order placed through the official checkout gives you, so buying there keeps your guarantee intact.
