Sisu is a premium vitamin company. Since our inception in the spring of 1980, we’ve embodied the same belief; it’s more effective to help the body prevent illness and disease than to treat it after the fact. Sisu is a Finnish term that translates to fierce determination and inner strength. We live this by combining the wisdom of nature with the knowledge of modern medicine, to craft science-based supplements that promote balance and wellbeing. Along with an uncompromised commitment to quality, innovation, and education, Sisu has helped define Canada’s vitamin and supplement industry. No matter where you are on your health and wellness journey, we have a superior product to help you feel your best.
