Collagen is sourced from animal tissue, which makes contaminant screening the test that matters. These products carry a published third-party test.
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.
