Manufacturer statement
WeightWorld’s own product page says the tablets are “Backed by our 90-day money-back guarantee” and the brand’s separate “Third-Party Tested Supplements” page says “we send our supplements to accredited third-party laboratories to verify purity and quality” and that “A wide range of our wellness supplements undergo third-party testing to screen for heavy metals.” However, I did not find an independently verifiable COA/lab report or a certifying-body registry entry for this specific Vitamin B12 1000µg product.

Testing claimed
Manufacturer statement
Nutravita’s Ingredients page says: “You’ll be pleased to know that our products do not include any genetically modified ingredients and any ingredient selected goes through strict testing to make sure it complies with EU standards.” It also says: “The testing is done in-house at the manufacturing site…” and describes disintegration/friability tests. On the B12 Amazon listing, the product page itself only shows marketing claims like GMP-certified facilities and “bioavailable form,” not an independently verifiable third-party test/certification for this specific B12 product.
