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 verified2 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?🇺🇸Jarrow Formulas, Inc.corporation · CALIFORNIA, USA
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. Jarrow Formulas Inc recalled a different product on January 15, 2018. FDA has since closed that case. The recalled item was “Jarrow Formulas Liquid L-Carnitine; 16 fl oz.…”

Every ingredient shows its amount · 2 ingredients listed.
Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
Evidence and sources
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
Locked evidence record →Open the full source-linked findingCheckedCan you trust the review pattern?
We can see 67 of this product’s 880 reviews — the count rose between July 18, 2025 and July 30, 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 813 to 880 between July 18, 2025 and July 30, 2026. The largest rise inside any single 30-day window was about 16, so the count moved in steps rather than in one burst.
