Our Story

Nutritional supplement usage is commonplace, with millions of people taking one every day. Yet, back in 1955, when the Douglas Laboratories story began, supplements were not part of the mainstream. Sam Lioon, company founder, was a nutritional pioneer. He saw an opportunity to help individuals improve their health, and began selling nutritional supplements directly to healthcare professionals. From that humble beginning, Douglas Laboratories has grown into a globally recognized leader in the development and manufacturing of innovative, science-based nutritional supplements, designed to help healthcare practitioners who are focused on the healthy aging and active lifestyles of their clients.
