Yu Sleep Ingredients: What Is in the Bottle, Line by Line

Reading a label before you commit is a good instinct, and this one is easy to read. The Yu Sleep ingredients break down into three named nutrients, a seven-part blend and a handful of helpers that keep the liquid pleasant to take. We go through each, give you every amount the panel prints and add a gentle note on why the ingredient is there. Roles come from how these ingredients are usually described and from the brand’s own pitch, so read them as background and not as promises.

The Yu Sleep ingredients at a glance

Below is the Supplement Facts panel, followed by the same information as a table. One serving is 2 mL, meaning two fills of the dropper, and a bottle supplies around thirty of them.

Weight per 2 mL	Listed as
637 milligrams	Proprietary blend (seven ingredients, one combined figure)
0.9 milligrams	Melatonin
0.5 milligrams	Vitamin B6 from pyridoxal 5-phosphate
0.5 milligrams	Vitamin B2 from riboflavin 5-phosphate

No daily-value percentages appear, so we do not quote any. Since only the blend’s total is printed, we also refrain from guessing how it splits among its seven members.

Three named nutrients

Melatonin, 0.9 mg. The best-known name on the list. The body produces this hormone as evening arrives, which is why makers of bedtime products add it. It is also one of the two reasons for the doctor check described further down.

Vitamin B6, 0.5 mg. Supplied in its active pyridoxal 5-phosphate form. Reference sources typically describe B6 as a vitamin that helps the body process food and keeps the nervous system working normally.

Vitamin B2, 0.5 mg. Supplied as riboflavin 5-phosphate. Like its neighbor, it is usually discussed in terms of turning food into energy. The brand counts both B vitamins among its ten, which sits well with the Nerve Support wording on the front of the bottle.

The seven-part blend, one by one

Together these make 637 mg per serving, according to the panel. We have grouped them by the way they are usually described.

• Calming plants: apigenin, a plant compound best known from chamomile, and lemon balm extract, a leafy relative of mint that has long been brewed into relaxing infusions.
• Amino-acid style helpers: L-theanine, found naturally in tea and often chosen for a relaxed, unhurried feeling, and GABA, a compound the nervous system makes naturally, which supplement makers add for its calming reputation.
• A mineral partner: magnesium glycinate, magnesium bound to the amino acid glycine. Magnesium is generally linked with muscle and nerve function, the angle the brand takes.
• A fruit ingredient: red tart cherry juice concentrate, a staple of evening and recovery products.
• The serotonin-pathway one: 5-HTP from Griffonia seed extract, a compound the body uses on the way to making serotonin. It is the second reason for the doctor check below.

Why a blend instead of a hero ingredient

As the brand tells it, a calm evening has several moving parts: a quieter mind, a looser body and a steady night-time rhythm. So rather than lean on one star ingredient, it mixes minerals, plant extracts, amino acids and a fruit concentrate with melatonin and two B vitamins. Whether that mix suits you only your own evenings can show, which is the point of the refund promise.

The brand’s phrase is “10 deep-sleep ingredients.” The sum is simple: seven in the blend plus melatonin, B2 and B6. A neat table of the same label sits on the ingredients page of our hub.

Reading a proprietary blend sensibly

This format is common in supplements. The maker names the members of the blend and gives one combined weight, without a figure for each. Yu Sleep does exactly that for its seven, with 637 mg as the total. It does not make the label unclear. You can still see which ingredients are inside and how heavy the blend is overall, which is what you need to compare formulas by name. If you like to check items against other products, the names above are your starting list.

What else is in the bottle

The remainder is there for body, taste and shelf life. Sweet and smooth: glycerin, medium invert syrup and erythritol. Tangy and preserved: citric acid, sodium citrate and potassium sorbate. Texture: gum arabic and xanthan gum. The base is distilled water, with natural flavors to finish. That mix explains why this is a pleasant liquid you take straight from the dropper.

Taking it

Directions are short. Fill the dropper twice for 2 mL and take it in the evening before bed. A 2 fl. oz. bottle gives roughly thirty servings, so one bottle is a month. The brand suggests at least three weeks of nightly use and offers a memory trick: leave the bottle on the bedside table. Safety details are covered in our side-effects guide.

A calm note on melatonin and 5-HTP

Both are in the formula, so a short chat with a doctor or pharmacist is wise if you use an antidepressant, a remedy for sleep or anxiety, or a blood pressure medicine, or if you are pregnant or nursing. The product is made for adults, and it is not meant for before driving or working with machinery. Prescribed medicines continue as your clinician set them.

What the label costs per night

Pack	Per bottle	Per evening
Six bottles	$49	about $1.63
Three bottles	$59	about $1.97
Two bottles	$69	$2.30

The six- and three-bottle packs include free delivery and three digital downloads, and the two-bottle pack adds postage. A 60-day refund promise covers all three; our refund guide explains the steps.

Comparing the label with other sleep products

If you are comparing bottles, three questions make the exercise quick. How much melatonin does one serving give? Here the answer is 0.9 mg per 2 mL. Does the maker name every ingredient? Yes, all ten appear by name. And are all amounts shown? Three are, and the blend is shown as a single 637 mg figure. Asking the same three questions of any other sleep liquid lets you compare like with like, and it shows why a printed, readable panel counts for something when you are deciding where to spend your money.

Who the formula is built for

Judging by the brand’s positioning, the label fits adults who prefer a liquid to pills, enjoy reading what goes into a supplement and want a short evening step based on familiar ingredients. If that sounds like you, clear figures for melatonin and the two B vitamins plus an honest blend total are a fair reason to run the trial. We score the offer 4.5 out of 5 as editors; no customers contributed to that number.

The bottom line

Yu Sleep sets a readable label behind an undemanding routine: ten ingredients, two fills of a dropper, about thirty servings per bottle. The surest way to learn whether those ten suit you is to use the bottle, and the lower price at six bottles, together with the refund promise, makes that pack the easy pick.
