Who we are

More than 30 years of Private Label Performance

Established in 1980, Magno-Humphries Laboratories has earned its reputation as a reliable, science-driven maker of dietary supplements, herbal products and OTC pharmaceuticals for private label customers as well as its own Optimum® and MHL® brand lines.

The company was founded by Thelma Magno, who combined her own health food background with an assembled team of industry veterans in nutritional product development, manufacturing and marketing. These are the people who understand the science of dietary supplements, as well as the servicing of private label customers and the exacting standards of OTC production.

In the 75,000-square-foot manufacturing facility in Tigard, Oregon, the staff of Magno-Humphries Laboratories produces more than 500 products that are available in many countries worldwide.
