Manufacturer statement
KAL’s product page says: “Trust Built On Testing” and lists “Passed Testing for Heavy Metals,” “Passed Testing for Microbials,” “Passed Testing for Contaminants,” and “Passed Testing for Physical Properties.” The brand blog also says KAL “test[s] every batch of raw materials” and that “every product we make is backed by rigorous standards like ISO and cGMP,” but I did not find independently verifiable third-party lab reports or a certifying-body registry entry for this specific product.
