Yu Sleep Ingredients: Melatonin, B2, B6 and the 637 mg Blend, Explained

Flip the Yu Sleep bottle over and the panel is short and easy to read: three named nutrients with amounts, then a single blend with one total. This page goes through it line by line. The seller’s framing of the whole formula is evening support for unwinding and deeper rest, but every figure below comes straight from the label. On the front, the bottle carries the wording “Advanced Nerve Support Formula.”

The Yu Sleep panel at a glance

Every figure below is for one serving, 2 mL or two full droppers. A 2 fl. oz. bottle holds about 30 servings.

Active	Amount	Plain-English note
Melatonin	0.9 mg	A hormone the body produces after dark
Vitamin B2	0.5 mg	A B vitamin, listed as riboflavin 5-phosphate
Vitamin B6	0.5 mg	Another B vitamin, listed as pyridoxal 5-phosphate
Proprietary blend	637 mg	Seven named items that share one total

That is the whole active panel, and the milligram figures are the ones we quote.

Melatonin

The body produces melatonin on its own as evening comes, and it is sold as a supplement too. The Yu Sleep label gives 0.9 mg per serving, so you can set it next to any other bottle at home and compare directly. As it is a hormone-related ingredient, our safety guide deserves a quick look before you start.

Vitamins B2 and B6

Two B vitamins join the melatonin, 0.5 mg each. Both are printed in their phosphate forms, with B2 as riboflavin and B6 as pyridoxal. The seller counts them in its tally of ten and gives neither a stand-alone job, and we follow that lead.

The 637 mg proprietary blend

Under a proprietary blend, several ingredients share one combined weight. For Yu Sleep the shared figure is 637 mg per serving, and its seven members are named but not individually weighed. We will not invent a split. Here is what each one is:

• Red tart cherry juice concentrate. Juice from tart cherries, reduced to a concentrate.
• Magnesium glycinate. Magnesium paired with glycine, an amino acid.
• Apigenin. A compound that occurs in chamomile and parsley.
• Lemon balm extract. An extract of a herb that belongs to the mint family.
• 5-HTP. Short for 5-hydroxytryptophan, sourced here from Griffonia seeds.
• L-theanine. An amino acid that turns up in tea.
• GABA. Gamma-aminobutyric acid, a compound found naturally in the body.

We say what each item is and nothing more. Promising a specific effect for one member of a blend would claim more than the label does, so the aim stays attached to the formula as a whole.

What “10 ingredients” means

Ten deep-sleep ingredients is the seller’s phrase. The arithmetic is simple: the blend contributes seven, and melatonin and the two vitamins make it ten.

Other ingredients

What remains makes up the liquid base and the taste. The label lists distilled water, glycerin, medium invert syrup, citric acid, erythritol, sodium citrate, natural flavors, gum arabic, xanthan gum and potassium sorbate. If you steer clear of a particular sweetener or additive, reread that line before you order.

Habits for reading any label

A handful of routines make comparisons painless.

• Start with the serving size. Here it is 2 mL, so each figure covers two droppers.
• Spot blend totals. This label has exactly one.
• Match units. Milligrams against milligrams, and note the form after each name.
• Scan the base. Water, sweeteners and thickeners sit under other ingredients.
• Show it to a pharmacist. A printed panel makes medicine questions quick.

The seller’s own description

On its own pages, the brand describes a dropper-based liquid for evenings. The pitch centers on a quieter head at bedtime and fewer 3 AM wake-ups, with the aim of helping you unwind, drift off and rest more deeply. We pass that on as the seller’s view of the whole formula, not as an outcome we have measured.

Using it

The routine is one serving in the evening, two full droppers, ahead of bed. According to the seller, you should use it daily for 21 days or more and park the bottle on the bedside table. Each bottle runs about a month, so the three packs cover roughly 60, 90 and 180 nights. It is for adults. If you take prescribed medicine or are pregnant or nursing, show your doctor the label first and continue with whatever was prescribed.
