Heritage & History

Carlson Labs was founded in 1965 in Arlington Heights, Illinois by Susan and Carl Carlson, establishing a family supplement company that would specialize in high-quality fish oils and fat-soluble vitamins at a time when the American supplement industry was in its earliest stages.

For 60 years, the Carlson family has maintained manufacturing in the Chicago suburbs, building a reputation for quality omega-3 fish oils that has made the brand a consistent recommendation among nutritionists and integrative medicine practitioners. The Norwegian connection in Carlson's fish oil sourcing — Norwegian cod liver oil was the brand's founding product — reflects an early commitment to using premium raw material sources.
