Yes. Zinzino has 14 products with published Informed Sport certificates in our index, backed by 79 batch certificates, most recently tested 2026-07-17. Certification applies per product, not to everything the brand sells: check the table for yours.
Brand vs product vs batch. Informed Sport certifies specific products, and its program tests specific batches of those products. "Certified brand" is shorthand: what exists in the record is a certificate for a product, backed by tested batches. That is what the table below shows, and a product missing from it may simply have no certificate we can see.
What this list is. Every product below has a published certificate from an independent testing program. That means a named third party tested it and released the result. It does not mean the product is safe, pure, or better than one that is not listed, and a product missing from this page may simply have no certificate we can see.
