Isagenix is a product marketed as a "complete system" for cleansing the body to produce weight loss and energy.  It is sold on the Isagenix website and from independent retailers.  The propitiatory blend of ingredients in their Cleanse for Life drink includes aloe vera, trace minerals, the herbs Pau d’Arco inner bark, suma root, eleutherococcus senticosus root extract, burdock root, fennel seed, peppermint, and licorice root, the amino acid methionine, and the nutrients betain HCL, choline bitartrate and inositol.  None of these ingredients is a proven weight loss aid but neither are they harmful, and some dieters get a psychological boost from starting a behavior change program with a cleanse; however, the weight loss attributed to Isagenix comes from replacing high calorie "real food" with low calorie liquids.
