When Isagenix was first founded in 2002, the company identified the practice of intermittent fasting as a key method for achieving substantial health benefits. Isagenix developed its own version of intermittent fasting through “Cleanse Days,” featuring Cleanse For Life, an antioxidant and botanical-rich beverage developed to support the body’s own detoxification mechanisms. These Cleanse Days were also paired with quality, science-based nutrition and calorie restriction comprising “Shake Days.”
