Products and business model
Isagenix uses a multi-level marketing model.
Isagenix sells nutritional products such as protein shakes, weight loss supplements, diet snacks and meals, and other dietary supplements. The company also sells cosmetics and "Wealth Creation" product bundles which are paired with the multi-level marketing sales model of the company.
Harriet A. Hall of Science-Based Medicine published a lengthy critique of Isagenix products, noting that claims made about the products are false and misleading, and that the amount of vitamin A in some of the products is dangerous and goes against the recommendations of The Medical Letter.
According to a report by Australian consumer organization CHOICE, the company's "nutritional cleansing" product makes claims which are not supported by science. Additionally, other Isagenix weight-loss products are similar in content to much cheaper store-bought alternatives. The report also describes instances of unqualified associates providing medical advice about the products, which is prohibited by the company.
A study funded by Isagenix in 2012 by the University of Illinois at Chicago examined the effect of intermittent fasting in combination with a liquid diet consisting of Isagenix Isalean Shakes or a food-based (National Cholesterol Education Program Therapeutic Lifestyle Changes) diet. Intermittent fasting in combination with Isalean led to a reduction in fat mass 9% more to that of intermittent fasting in combination with a food-based diet, as well greater reductions in total and LDL cholesterol and several other factors associated with coronary heart disease risk and loss of visceral fat.
