Checked against public sources between July 23 and August 31, 2026 · LookCloser does not sell or recommend supplements.

Does the marketing hold up?

FDA recall appears in this brand's history. An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.

“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.

FDA recall appears in this brand's history

An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.

Evidence and sources

This recall is not about the product on this page. Lyons Magnus, Inc recalled a different product on July 22, 2022. FDA has since closed that case. The recalled item was “Optimum Nutrition Gold Standard 100% Whey Chocolate 11 fl oz (325mL). UPC 7 48927-06409 4. Shake well.…”

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 3.3 g of creatine monohydrate per serving. Studies we found used 3 g–5 g a day, so this sits inside that range.

0studied 3 g–5 g

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

Same UPC/GTIN observed across 2 sellers. Amazon was lowest at $24.99; iHerb was highest at $28.39 — a $3.40 range at check time.

The brand-page price is shown as a shopping lead only. It is excluded from the exact-product price difference because the page does not publish this record's matching UPC/GTIN.

The observed listing and related brand page repeat 30 servings, 175 mg. That confirms cross-page consistency of the published claim, not the product contents.

Reference prices only · no affiliate links · every compared seller must publish the matching UPC/GTIN.
