We are a family owned and operated company that was established in 1987. We operate two facilities with four analytical laboratories and state-of-the-art manufacturing and packaging equipment from manufacturers such as Bosch, Korsch, Munson, and Vector. If you haven’t already, take a virtual tour of our encapsulation, tableting, packaging, and laboratories.

Today, we are one of the most credentialed dietary supplements contract manufacturers and packagers in the United States. (We were one of the first ten companies to obtain NNFA GMP certification in 1999 before FDA promulgated its dietary supplement CGMPs in 2007.) Since then, our facilities have met or exceeded U.S. FDA CGMPs (21 CFR 111, et seq.); we are also NPA GMP and CCOF Organic certified, and NSF GMP, ISO 9001:2015 and USDA NOP registered.

We manufacture two-piece capsules in various sizes (#4 to #000), coated and uncoated tablets in various shapes, sizes and colors, and ready-to-mix powder drink mixes ranging from pre-workout, post-workout, and meal replacement formulations. We can package dietary supplements in bottles, jars, cans, and blister cards and cartons. We also manufacture human food grade specialty pet food vitamin and mineral premixes.

Our clients are located around the globe. They range from single-product direct-to-consumer brands to multi-product mass market vitamin, mineral, and dietary supplement brands that are sold in big box retailers.
