“IN THE USA FROM GLOBALLY SOURCED INGREDIENTS: Manufactured and packaged in the United States from globally sourced”
Evidence →“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.
“THIRD-PARTY TESTED: Every batch of our glutathione liposomal supplement is tested in the USA for heavy metal safety through accredited”
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.
We looked and found no public proof. That does not count against the product.

CheckedIs the label honest?
Every ingredient shows its amount · 5 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.

Evidence and sources
Written reviews rose from 0 to 152 between April 21 and September 1, 2026. The largest rise inside any single 30-day window was about 49, so the count moved in steps rather than in one burst.
