Does the marketing hold up?

Ingredient amounts are hidden inside “Antioxidant Blend”. The panel lists “Antioxidant Blend” (3000 mg) as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.

Is the dose real?Panel read — dose not verified19 ingredients listed; no advertised amount we could confirm against them

Is it tested?Claimed — no lab or certificate found

Is it the real thing?Barcode matches outside records
Trouble on record?No recalls found

“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

Marketing claims, checked

The checks, one by one

The public sources did not settle the marketing promises on this label.

Partly confirmed1

“COLLAGEN PEPTIDES: This liquid collagen contains 4,000 mg of hydrolyzed collagen peptides (types I & III) to support skin elasticity &”

Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed.

Evidence →

Ingredient research can support context, but it is not a trial of this exact product.

?Couldn’t verify independently2

“PARTY TESTED, USA MANUFACTURED: NatureWise Liquid Collagen are 3rd party tested for purity and efficacy and manufactured in the USA with…”

“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.

“PARTY TESTED, USA MANUFACTURED: NatureWise Liquid Collagen are 3rd party tested for purity and efficacy and manufactured in the USA with…”

No named laboratory or lot-specific certificate was found for this exact product. The exact brand page names no testing issuer and links no product-bound report. NSF, IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur.

Evidence →

We looked and found no public proof. That does not count against the product.

Headlines first. Open evidence only when you want the source trail.

CheckedWho is behind it?

The barcode identity checks out · 855724007831.

The barcode matches, so we are checking the right product rather than a look-alike.

Evidence and sources

The brand's store lists this exact barcode as “Liquid Collagen” (variant: Mixed Berry / Tubes / 10 Pack) — identity confirmed across retailer listings.

CheckedCan you trust the review pattern?

Reviews rose from 101 to 163 between July 7, 2025 and June 30, 2026 — no sudden jump.

A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.

Evidence and sources

Written reviews rose from 101 to 163 between July 7, 2025 and June 30, 2026. The largest rise inside any single 30-day window was about 10, so the count moved in steps rather than in one burst.

What remains open 3
  • No FDA recall matched this brand in the current search.
  • We have not found a public label filing for this exact product.
  • Barcode checksum is valid; no independent product record was found.

These are evidence gaps, not strikes against the product.

Research behind the findings

Dose and research context

We could not match an amount on this product to a studied range for the same ingredient, so these links are ingredient background rather than a measurement of this product.

Background reading

What the research says about these amounts

Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.

The panel lists 4 g of collagen peptides per serving. Studies we found used 2.5 g–15 g a day, so this sits inside that range.

0studied 2.5 g–15 g

Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
