Tier 1 Nutritionals

Established in 1957 by Herbert “Tommy” Thomsen and Reginald Comstock, the T.C. Products company name has been associated with quality people, quality products, and reliable service for nearly 60 years. In 2012, our company made a significant investment into our future by renovating and expanding our production capacity and capabilities. New, state-of-the-art blending and packaging equipment was installed and the next chapter of our company’s history was about to begin. We have since expanded our vitamin & trace mineral premix manufacturing services and have increased the contract manufacturing services that we provide to innovators and manufacturers of high-value, branded feed ingredients. Today, feed ingredients manufactured by Tier 1 Nutritionals are sold not only to livestock producers and feed manufacturers in our home state of Wisconsin, but now throughout the U.S. and around the world. In 2014, our company successfully created and implemented an extensive food safety program. All elements of our operation were reviewed and fine-tuned to support this commitment to product quality and safety. In September 2014, we completed this project and became a HACCP Certified feed ingredient blending facility.


Tier 1 Nutritionals provides contract blending and packaging services of vitamin and mineral premixes, forage inoculants, feed enzymes, Direct Fed Microbials, and other functional feed additives.
