How We Make and Test Our Chews
Every Oliver's Gut chew is made in the USA with U.S. and imported ingredients, in an FDA-registered facility that is GMP certified, SQF certified and NASC certified. Our products are third-party lab tested, and our ingredients come with a certificate of analysis from the supplier.

What an ingredient certificate of analysis checks
A certificate of analysis (COA) is the lab report that comes with each ingredient lot. It covers identity, purity and safety:
- Identity: the ingredient is what it says it is, confirmed by methods such as TLC fingerprinting.
- Heavy metals: lead, arsenic, cadmium and mercury below set limits.
- Microbial safety: E. coli, Salmonella and Staphylococcus absent; total plate count and yeast and mold within limits.
- Probiotic count: the probiotic blend's certificate reports its count of colony-forming units (CFU).
What's not in our chews
No artificial flavors, no artificial preservatives and no artificial colors.
