A Calmer Night. A Brighter Morning.

What Is YU SLEEP?

YU SLEEP is a liquid dietary supplement marketed for nighttime relaxation and sleep support. Rather than using a tablet or capsule, the formula comes in a dropper bottle designed to fit into an evening routine.

According to the manufacturer’s August 2026 formula announcement, one serving contains 0.9 mg of melatonin, 0.5 mg of vitamin B2, 0.5 mg of vitamin B6 and a 637 mg proprietary blend of seven additional ingredients.

The formula combines ingredients associated with different aspects of sleep-related research, including circadian timing, relaxation and normal nervous-system function. Their inclusion does not establish that the finished product has been clinically proven to produce a particular sleep outcome.

How Does YU SLEEP Work?

The idea behind YU SLEEP is to combine several sleep-related ingredients in a single liquid serving. Each ingredient has a different biological or nutritional role, although the clinical effects of the complete combination have not been established by the ingredient list alone.

Melatonin and circadian timing

Melatonin is a hormone naturally produced by the body, particularly in response to darkness. It plays a role in communicating nighttime signals to the body’s internal clock. YU SLEEP’s published formula contains 0.9 mg per serving.

Botanical ingredients

Red tart cherry, lemon balm and apigenin contribute the botanical component of the formula. These ingredients have been investigated individually in sleep- and relaxation-related research, although study designs, extracts and doses differ.

Amino acids and related compounds

L-theanine, GABA and 5-HTP are included in the proprietary blend. They are associated with different neurological pathways, but the precise quantity of each ingredient in YU SLEEP is not separately disclosed.

For that reason, results from studies of individual ingredients should not be interpreted as guaranteed results from this particular combination.

Complete YU SLEEP Ingredient Analysis

1. Melatonin — 0.9 mg

Melatonin is the best-defined sleep-related ingredient in the published formula because its individual quantity is disclosed. Its effects depend on factors such as dose, timing and the reason a person is experiencing sleep difficulties.

2. Red tart cherry concentrate

Tart cherries contain naturally occurring polyphenols and small amounts of melatonin. Some studies have explored tart cherry products in relation to sleep, but results from a specific juice or extract cannot automatically be applied to YU SLEEP.

3. Magnesium glycinate

Magnesium is an essential mineral involved in numerous physiological processes, including normal muscle and nerve function. Magnesium glycinate is one of several supplemental forms. YU SLEEP includes it in the proprietary blend without disclosing its individual quantity.

4. Apigenin

Apigenin is a flavonoid present in various plants, including chamomile. It has attracted scientific interest for potential effects involving neurological signaling, but the clinical evidence for isolated apigenin as a sleep supplement remains limited.

5. Lemon balm extract

Lemon balm, also known as Melissa officinalis, has a long history of traditional use. Research has investigated selected lemon balm preparations for relaxation and related outcomes. The amount included in YU SLEEP is not individually disclosed.

6. L-theanine

L-theanine is an amino acid naturally found in tea leaves. It has been studied for relaxation-related effects and sleep quality in certain populations. Study results depend on the preparation and quantity used.

7. GABA

Gamma-aminobutyric acid, commonly called GABA, is a naturally occurring inhibitory neurotransmitter. Oral GABA supplements have been studied for relaxation and sleep, although findings and mechanisms remain under investigation.

8. 5-HTP

5-hydroxytryptophan, or 5-HTP, is involved in serotonin production. Because it can interact with medications affecting serotonin, people taking antidepressants or other serotonergic medicines should consult a healthcare professional before use.

9–10. Vitamins B2 and B6

The published formula includes 0.5 mg each of vitamins B2 and B6. Both are essential nutrients involved in normal metabolic and nervous-system processes. Their presence does not, by itself, establish an additional sleep benefit.

YU SLEEP Supplement Facts Explained

The manufacturer’s August 2026 announcement describes a 2 mL serving with approximately 30 servings per bottle. Its published formula includes 0.9 mg melatonin, 0.5 mg vitamin B2, 0.5 mg vitamin B6 and a 637 mg proprietary blend.

The proprietary blend contains seven ingredients, but their individual quantities are not specified. This matters when comparing the formula with clinical research because published studies often use particular ingredient doses.

Always check the physical Supplement Facts label on the bottle you receive. Manufacturers can update formulas, serving sizes and packaging.

How to Take YU SLEEP

The manufacturer’s published directions describe a 2 mL serving—approximately two full droppers—around 30 minutes before bedtime. The directions printed on your actual bottle should take precedence.

• Read the complete bottle label before use.
• Measure the serving using the supplied dropper.
• Follow the current timing and serving instructions.
• Keep the product away from children.
• Consult a clinician about medication interactions or medical conditions.

A consistent bedtime, reduced evening light exposure and a comfortable bedroom can also contribute to a healthy sleep routine. A supplement is not a replacement for appropriate evaluation of persistent sleep problems.

What Published Research Can Tell Us

Research into sleep-related supplements includes studies of melatonin, selected botanical extracts and amino-acid ingredients. However, research on one ingredient does not prove that every product containing it will produce the same effect.

Melatonin has been studied extensively in relation to circadian timing and selected sleep concerns. Tart cherry, lemon balm, L-theanine and other ingredients have smaller and more varied evidence bases.

A clinical study specifically testing the finished YU SLEEP formula would provide more direct information about its effects than studies of individual ingredients. No such product-specific clinical trial has been independently established in the sources reviewed for this page.

For additional context, consult the NIH’s melatonin information and the manufacturer’s published formula disclosure.

YU SLEEP Customer Reviews and Experiences

Customer reviews can be useful for learning about product format, ordering experiences, taste preferences and individual routines. Sleep-related experiences, however, can vary considerably from person to person.

Promotional testimonials should be distinguished from independently verified customer reviews. Names, photographs, ratings and purchase-verification labels should only be published when their source and permitted usage are established.

The manufacturer currently requires written permission before affiliates reproduce its customer testimonials or photographs. Once an approved testimonial pack is supplied, this page’s horizontal review section can be expanded with authorized named reviews, original ratings and source information.

Review the terms presented with your specific order, particularly if the offer includes a subscription or a special promotional package.

Who Might Consider YU SLEEP?

YU SLEEP may interest adults who prefer a liquid supplement format and want to examine a formula containing melatonin alongside botanical and amino-acid ingredients.

Individual suitability depends on factors including medication use, health conditions, pregnancy or breastfeeding, and the reason for sleep difficulties.

Because the formula includes 5-HTP and melatonin, consulting a qualified healthcare professional is particularly important when taking prescription medication or managing a medical condition.
