Quality Control and Testing

We at Hillestad Pharmaceuticals® are aware that consumers want to know exactly what is in their supplement.

Manufacturing PhotoHere is a brief overview of our quality-related activities: Written specifications are established for all our materials. The incoming raw materials are tested for identity, strength, purity, composition and limits of contaminants (such as heavy metals, microbes) and will only be released to production if all specifications are met. Testing and monitoring continues throughout the production process (blending, tableting, coating, etc.).

The finished product is again tested for a variety of parameters, such as weight, disintegration, as well as strength (potency) of labeled dietary ingredients. Testing is performed either in our own Quality Control laboratory or by qualified third-party labs. Further inspections are performed by our Quality Control Department once the product has been packaged.

Quality Control photoOur products are only released for distribution if they pass the entire testing program. Furthermore, the lot number on each container allows us to track the product since the entire production process is meticulously documented.

We are proud of this rigorous quality control program. It provides us with continuous confirmation that our production process delivers supplements of the highest quality.

We also invite our interested customers to take a tour of our manufacturing facility in Woodruff, Wisconsin to see all aspects of manufacturing and testing first-hand!
