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. Metagenics, Inc. recalled a different product on July 3, 2014. FDA has since closed that case. The recalled item was “UltraBalance Protein Powder, Net Wt. 14.8 oz (420g)”. …
Locked evidence record →Open the full source-linked findingThe observed listing says it is tested, but names no lab or certifier.
A testing badge without an issuer or report is a marketing claim, not evidence. Ask for the lab name and lot-specific report.
Evidence and sources
The observed listing claims third-party testing without naming a lab or certifier. No product-bound report is saved, so the claim cannot be verified as stated. NSF, IFOS, USP, and Informed-Sport were not checked in this record.

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.
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 75 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits below that range.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
The panel lists 15 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits inside that range.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
