About Carlson

Carlson began in Chicago in 1965 as one woman’s mission to improve the health of her family by creating nutritional supplements with high-quality ingredients. Susan Carlson’s father suffered from heart issues but found relief after taking vitamin E. Inspired by this discovery and her background as a pharmacist, Susan created one of the first full lines of vitamin E worldwide, and the product line continued growing to meet the health needs of local families. Carlson began popping up on store shelves around Chicago, and the wave continued across the nation. 

In the early 1980s, Carlson helped launch the omega-3 market in North America, importing our first wild caught, sustainably sourced fish oils from Norway. Today, the commitment to helping families live a healthier lifestyle continues, as the next generation of the Carlson family leads the company. Carlson now offers more than 200 vitamins, minerals, omega-3s, kids' products, and other high-quality nutritional supplements. At Carlson, our family cares about the health of your family.
