Quality Assurance

TR Nutritionals’ Vendor Qualification Program allows our customers to be confident knowing they are receiving only the highest quality raw materials. Respected, independent laboratories in the United States, as well as China, are used to ensure our raw materials meet required product specifications. To smooth out the process for our customers’ GMP requirements, we also participate in the SIDI (Standardized Information on Dietary Ingredients) program to ensure prompt and consistent manufacturer information.

We partner only with those manufacturers able to consistently meet required quality standards, and our China-based staff regularly performs site visits and audits to ensure regulatory compliance, and provide guidance on improvements at the manufacturing site which will keep them up to date.

Of course, we always welcome customer site visits to any of our manufacturers.
