Manufacturer statement
WeightWorld’s UK site says: “We are committed to complete product transparency, with every formulation backed by rigorous analytical testing to assure authenticity, quality, and consumer trust” and “we send our supplements to accredited third-party laboratories to verify purity and quality without any internal bias.” The iron product page also says the product is “GMP-certified” and the US page says “100% GMP-Certified Product Range” and “thoroughly tested, and verified for identity, purity, strength, and composition,” but I did not find an independently verifiable registry entry or product-specific lab report for this exact iron product.
