Sannmerk is a Canadian product intelligence platform operated by Northken Inc., designed to help people identify, compare, and evaluate consumer products using verifiable information. Its public registry indexes 261,694 products from five sources, including food data from Open Food Facts and health product information from Health Canada. Products can be searched by GTIN, DIN, or NPN, supporting checks of identity, history, observed prices, and provenance before purchase.

The registry covers categories such as drugs and natural health products, and allows users to browse by brand, source, category, or regulatory framework. Sannmerk also organizes information about ingredients and substances, materials and inputs, facilities, manufacturers, distributors, and companies. Other features include product comparisons, market flyers, promotions, new-product listings, and traceability frameworks.

Methodology notes, source and licence details, classifications, a glossary, regulator information, and update status help users understand the available data. Users can also access an RSS feed, contact the team, request a product, or report an error. Sannmerk’s stated aim is “truth in every product.”.
