Quality, Scalable, and Efficient Supplement Manufacturing

With over 40 years in the supplement manufacturing industry, we’ve learned a thing or two—and our expertise grows stronger every year. As does our capacity to serve our customers’ growing demands. In addition to our full-service manufacturing facilities in Vista, California and Manno, Switzerland, we’ve added our new facility in Carlsbad, California, expanding our capacity to provide high-quality capsule, tablet, and powder supplements for an international audience. We provide a vertically integrated model that allows us to quarantine ingredients, maintain tight control over the quality process, and offer competitive pricing.

Our vertically integrated model includes:

  • Materials receiving
  • Warehousing
  • Weighing and blending
  • Finished goods packaging
