Does the marketing hold up?
Testing claimed — documentation not found. 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. …

Evidence →No named laboratory or lot-specific certificate was found for this exact product. No exact brand product page was available for a document check. NSF, IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur.

CheckedIs the label honest?
Listing claim matches the Supplement Facts panel
The label promise and the Supplement Facts amount agree.
Evidence and sources
The listing claims 1 g; the photo-read Supplement Facts panel shows Vitamin C at 1 g per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.
Locked evidence record →Open the full source-linked findingCheckedIs the label honest?
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.

Reviews rose from 79 to 167 between August 14, 2025 and August 27, 2026 — no sudden jump.
A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.
Evidence and sources
Written reviews rose from 79 to 167 between August 14, 2025 and August 27, 2026. The largest rise inside any single 30-day window was about 12, so the count moved in steps rather than in one burst.
