How to read this report

What this is. We compare what a listing claims against what public records show — label arithmetic, barcode registries, NIH’s label catalog, FDA enforcement data, certification registries, and published research. Every statement below traces to one of those.

What the states mean. Confirmed = an outside source agrees. Contradicted = an outside source disagrees. Caution = something needs explaining. No data = we looked and found nothing — a gap, not a strike.

What it is not. A clean record is not an endorsement and never proof a product works. A thin record is not an accusation. We publish evidence and gaps; the conclusion is yours. Nothing here is medical advice.

Something wrong? Every figure is meant to be checkable — sources are named and linked. Send a correction and we’ll fix the record.

Panel, decoded

The 2.5 g creatine monohydrate claim matches the panel

MARKETING2.5 g — per-serving claim

PANELCreatine Monohydrate 2.5 g — same amountCreatine Monohydrate 2.5 g

matches panel

We did the comparison: the listing claims 2.5 g of creatine monohydrate, and the listing-image panel shows 2.5 g creatine monohydrate serving size 2 capsules. Those amounts agree. This is internal consistency, not independent lab testing.

Panel row	Amount	%DV	What to notice
Creatine Monohydrate	2.5 g	—	the real creatine number

FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a listed “proprietary blend” (legal, but a transparency yellow flag). A label stating no amount at all is non-compliant — a checkable red flag. This panel states amounts; any remaining comparison concerns the front-label framing.

Every check we ran

Confirmed evidence

What checked out3

These checks found support in the public record. They confirm specific facts, not the product as a whole.

✓

Every ingredient amount is disclosed

The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

Confirmed

✓

Barcode confirmed in an outside database

Open Food Facts resolves 748927021356 to "Micronized Creatine Capsules" (Optimum Nutrition) — consistent with this listing.

Confirmed

✓

The review count moved gradually, not in one burst

Written reviews rose from 940 to 1,011 between June 30, 2025 and July 26, 2026. The largest rise inside any single 30-day window was about 25, so the count moved in steps rather than in one burst.

Confirmed

Documented concerns

What needs caution2

These are documented contradictions or claims that need more evidence. They are separate from missing data.

Dose is lower than studies used

label claims 2500 mg/serving — below the range commonly used in research (3–5 g/day maintenance across trials (short loading phases use more)). A lower dose is not necessarily useless — but it is not the amount the research used. Sources: NIH ODS — Exercise & Athletic Performance fact sheet, Creatine stability by moisture and temperature (PubMed).

Caution

Dose claim implausibly high for a capsule

Claimed creatine 2,500.0 mg is 100% of the ≈2,500 mg serving (serving size on the label, keyed to UPC 748927021356) — above what gummy matrices realistically carry.

Caution

Unresolved public record

Why is this shown?

Everything we couldn’t verify is something a person can still ask about. Rather than leave gaps sitting as dead ends, we turn each one into a specific question — the exact document, citation, or number that would settle it — plus the things you can confirm yourself with the bottle in your hand.

Ask the brand or seller

Answered by the panel: 2.5 g of the 2.5 g headline is creatine. Which independent lab can confirm that amount in this product?

The panel resolves the front-label arithmetic. The remaining question is lot-specific contents and stability; published category testing gives context, not a test of this product.

Is this label filed with NIH’s Dietary Supplement Label Database (DSLD)?

Filing is voluntary, so absence proves nothing — but a filed label puts the full ingredient table on public record where anyone can read it.

Why is the creatine monohydrate amount below the dose used in published research?

There can be good answers — a more bioavailable form, a different intended use. Ask for the reasoning and any data behind it.

Most brands and sellers publish a contact route. A clear answer adds evidence to the record; no answer leaves the question open.

Check for yourself — no one’s permission needed

Compare the panel on the bottle in your hand to the one shown in this record.

Ours was read from listing photos and can contain reading errors. The physical label is the source of truth — if they disagree, tell us and we’ll correct the record.

Scan the barcode on the package and confirm it reads 748927021356.

A mismatch between the barcode on the box and the one on the listing is worth pausing over — it can indicate a different variant, a repack, or a counterfeit.

Check the lot number and expiry on the bottle against any COA you’re given.

A certificate that doesn’t name your lot doesn’t describe what you’re holding.

These are the open questions on this specific record — not a warning about the product, and not a suggestion to buy or avoid it. Getting them answered is how you decide for yourself.

What the listing promises — claim by claim

Why is this shown?

A listing’s promises are the reason people buy. Each one gets its own row: what was promised, what evidence would settle it, and what we could actually find. We never call a claim false — only whether proof proportionate to it exists on the public record.

Claim	Status	What we found
Benefit claim “Optimum Nutrition Creatine, Micronized Creatine Monohydrate Capsules, Supports Strength & Recovery, Banned Substance Tested, 2.…”	Partly supported We looked for: whether the ingredient doses on the label match the doses used in published research	Ingredient evidence exists; on dose: label claims 2500 mg/serving — below the range commonly used in research (3–5 g/day maintenance across trials (short loading phases use more)).

“No evidence located” does not mean a claim is false — it means the seller has not put evidence proportionate to the claim on the public record, and we could not find any. Absence of proof is not proof of absence.

This label vs. the doses studied

Why is this shown?

An ingredient can be well-studied at one amount and barely studied at the amount in your bottle. This lines the label up against the doses researchers actually used. It answers ‘are these the same numbers?’ — never ‘should you take this?’

Ingredient	Where this label sits	Reading
Creatine Monohydrate	shaded = doses used in studies (3 g–5 g) · bar = this label	2.5 g — below the studied range

Matching a studied dose does not mean the product works, and missing it does not mean it fails — it shows whether the label and the research are talking about the same amounts. Not a recommendation to take any amount.

Label math — claimed dose vs. serving mass

Why is this shown?

Simple physics: the claimed dose has to weigh less than the whole serving. We compare the milligrams promised on the label to the weight of one serving, from the label itself. If the claim fits — even at a small percentage, which is normal, since servings include binders and flavoring — the label is at least physically possible. Only a lab test can confirm what’s actually inside.

claimed creatine 2500 mg100% of serving mass — tiny doses are normal for potent activesserving ≈ 2,500 mg

The claimed creatine dose of 2500 mg fits within the ≈2,500 mg serving — physically possible. Only a lab test can confirm what’s actually inside.

A low percentage isn’t a red flag — most servings are mostly carrier, binder, and flavoring.

Show the arithmetic

creatine: 2500 mg claimed ÷ 2,500 mg serving mass = 100%. Serving mass source: listing-derived. Redo it yourself — that’s the point.

Ingredient science — creatine monohydrate · Grade A

Evidence: Human RCT meta-analyses (5+ indexed in PubMed for strength outcomes; ISSN position stand). PMID 40265319 · PMID 37144634 · PMID 39545789
Studied serving: 3–5 g/day maintenance (≈0.03 g/kg); optional loading 20 g/day split ×4 for 5–7 days.
This label claims 2,500.0 mg/serving — outside the studied 3–5 g/day range, if actually present (see verdict above).
Absorption: Creatine monohydrate is ~99% orally bioavailable when delivered intact — absorption is not the limiting factor; delivery-medium stability is.
Delivery medium: Creatine is stable as a DRY powder but hydrolyzes toward creatinine (inactive) in warm, moist, or acidic media. A gummy is an aqueous, often acidic matrix — the documented reason independent testing finds many creatine gummies far below label.
Kidney disease: consult a clinician before use.; Pregnancy/lactation: safety not established at supplemental doses.; Combine with adequate hydration.
