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.
Is the dose real?Panel read — dose not verified25 ingredients listed; no advertised amount we could confirm against them
What a serving costsNo price found for this exact barcode
Is it tested?No testing claim made
Who’s behind it?No exact match in USPTO
Is it the real thing?No barcode publishedso it can’t be matched against certification, recall or other retailer records
Trouble on record?Brand history — not this product
“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. Threshold Enterprises Ltd recalled a different product on September 10, 2019. FDA has since closed that case. The recalled item was “Source Naturals Dietary Supplement Brain Charge Advanced Cognitive Support 30 tablets, 60…”
Locked evidence record →Open the full source-linked findingCheckedCan you trust the review pattern?
We can see 27 of this product’s 477 reviews — the count rose between August 24, 2025 and July 31, 2026. That is too small a slice to say anything about the wider pattern.
A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.
Evidence and sources
Written reviews rose from 450 to 477 between August 24, 2025 and July 31, 2026. The largest rise inside any single 30-day window was about 18, so the count moved in steps rather than in one burst.

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 1.3 g of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits above that range.
0studied 8 mg–40 mg
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
