YU Sleep ReviewsIndependent Research & Buyer GuidesOur hierarchy of sources puts the current product label above everything else, including the vendor's marketing. This page transcribes the facts panel as we've verified it, explains each line in plain language, and flags exactly where the label's transparency ends.
The panel, transcribed
Serving size: 2 mL (2 full droppers) · Servings per container: about 30
| Line | Amount per serving | %DV |
|---|---|---|
| Vitamin B2 (riboflavin) | 0.5 mg | ~36% |
| Vitamin B6 (pyridoxine) | 0.5 mg | ~29% |
| Melatonin | 0.9 mg | † |
| Proprietary blend | 637 mg | † |
† Daily Value not established. Blend contents, in label order: Red Tart Cherry Juice Concentrate, Magnesium Glycinate, Apigenin, Lemon Balm Extract, 5-HTP (Griffonia simplicifolia seed extract), L-Theanine, GABA (gamma-aminobutyric acid).
Label tagline: "Advanced Nerve Support Formula." Format: liquid, 2 fl oz (60 mL) dropper bottle.
What the serving line means in practice
Two milliliters per night from a 60 mL bottle yields roughly 30 servings — a one-month supply per bottle, which makes the vendor's 2/3/6-bottle packages map cleanly onto 2/3/6 months. The dropper delivery also means no capsules, no swallowing, and a mildly flavored liquid rather than a herbal slog. If you travel, the bottle is carry-on friendly in size, though liquid rules at airport security apply to it like any other liquid.
The disclosed doses, read carefully
- Melatonin 0.9 mg — the panel's headline act. Below the 3–10 mg retail norm and inside the low-dose range studied for sleep onset with fewer next-day effects.
- B6 and B2 at 0.5 mg — near-nutritional doses that support the melatonin synthesis pathway rather than acting as sedatives. The percentages of daily value are meaningful here: these are supplement-the-diet amounts, which is appropriate for cofactors.
The blend line: what it tells you and what it hides
US labeling rules let manufacturers group ingredients under one blend weight, listed in descending order of predominance. So the panel confirms presence and rank order — tart cherry concentrate is the largest blend component, GABA the smallest — but not individual amounts. Divide 637 mg across seven actives and the average is about 91 mg; the true distribution is skewed toward the top of the list. For buyers who compare doses against published research (GABA studies often use 100–300 mg, L-theanine 100–200 mg, magnesium compounds several hundred mg), the panel is where that comparison hits its limit.
Vendor sales pages paraphrase formulas freely; labels are regulated. When our ingredient guide discusses evidence, and our review weighs the formula, the panel above is the document both are checked against. If a future bottle changes any line, this page should be re-verified against it before purchase decisions rely on it.
What the panel doesn't cover
The facts panel lists actives; inactive ingredients typical of a flavored liquid (sweeteners, flavor, preservatives, acidity regulators) appear elsewhere on the label and weren't independently documented in our desk research. If you manage sensitivities, sugars, or dietary restrictions, read the current bottle's full ingredient statement rather than relying on the actives panel or on any website, including this one.
How the label compares with the marketing
Mostly consistent, with two marketing additions that don't appear on the panel: "nano-enhanced" delivery (an unverified absorption claim) and the "sleep pressure reset" narrative (a framing, not a label statement). The panel itself makes no disease claims, as required for a dietary supplement, and carries the standard FDA disclaimer. That separation — restrained label, ambitious sales page — is typical of the category and exactly why we keep vendor claims and label facts in different columns throughout this site.
Supplement facts FAQ
Is 2 mL really two full droppers?
Per the vendor's directions, yes — two dropper fills deliver the 2 mL serving. Fill to the marked line rather than guessing, especially in the first weeks while you're judging how the product affects you.
Does the label state where it's made?
Vendor pages state US manufacturing in an FDA-registered, GMP-certified facility — a vendor claim about the site's status, not FDA approval of the product. The panel itself follows standard US supplement labeling.
Will the blend order ever change?
Formulas do get revised in this market. If predominance order or any dose changes, the label changes with it — re-check the current bottle or vendor page at purchase time if exact composition matters to you.
