Sisu Vitamins

Since its inception in the spring of 1980, SISU has held the belief that it is more effective to help the body prevent illness and disease, than to treat it after the fact. SISU is a Finnish term that can be translated as fierce determination and inner strength, which is shown through our commitment to combine the wisdom of natural remedies with the knowledge gained from modern medicine to produce science-based supplements that empower wellbeing. Along with an uncompromised commitment to quality, innovation, and education, SISU has helped define Canada’s vitamin and supplement industry, helping active and health-conscious consumers manage their health and wellness needs.
