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.

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.

Marketing claims, checked

The checks, one by one

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

Partly confirmed1

“Most Lifestyles: MaryRuth’s N-Acetyl Cysteine (NAC) Capsules are Non-GMO, Vegan, Made in a GMP”

“GMP-certified” describes factory processes, not what is in the bottle. The claim does not name a certifier or public register that a shopper can check.

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. MARY RUTH ORGANICS recalled a different product on October 28, 2021. FDA has since closed that case. The recalled item was “MaryRuth's Organic Infants Liquid Probiotic; Unflavored, a Dietary Supplement. 1 fl. oz.…”

CheckedIs the label honest?

Every ingredient shows its amount · 1 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 finding
CheckedWho is behind it?

The barcode identity checks out · 810104621168.

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 “N-acetyl-cysteine (NAC)” (variant: Default Title) — identity confirmed across retailer listings.
