We only list the country of origin if the finished product is made outside of the United States. If there isn’t a country of origin listed, it means the finished product was made within the US. We don’t release the names of our manufacturers on non-trademark supplements since we have contractual arrangements with them not to release their names or contact information. Bulk materials for trademarked ingredients come from the manufacturer that holds the trademark.

Regardless of country of origin, all of our manufacturers must be compliant with GMP regulations, and products are quality-control tested at multiple stages during processing and after we receive them to ensure they meet label claims for correct substance, purity and potency. We require our manufacturers to test for pathogenic bacteria (E.coli, Staph, Salmonella), fungal counts and heavy metals (lead, mercury, cadmium and arsenic). We also require manufacturers to verify compliance with FDA regulations for BSE (mad cow) if any bovine components are used. Manufacturers must also verify products are compliant with Proposition 65 for sale in California.
