For more than 50 years, Carlson Laboratories has been recognized as an innovator and leading educator in the field of high-quality nutritional supplements. The Carlson family?s interest in vitamins and minerals began when they experienced the benefits of vitamin E firsthand. Founder Susan Carlson?s father suffered from debilitating chest pain that limited his activities and forced him to stop working. He was unable to find relief until he came across the extensive clinical work of Doctors Evan and Wilfrid Shute of Shute Medical Clinic.
