Douglas Laboratories of Canada, Richmond Hill, ON

It’s hard to imagine life without nutritional supplements. Millions of us take 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 Americans 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.
