They don't. dotFIT products are part of an evidence-based program with all ingredients supported by science. dotFIT products are professional products sold by trained professionals, which is unlike any products sold in retail chains or through heavily marketed multilevel marketing companies (MLM) where unqualified friends sell things to uninformed friends. Do any of these companies have a peer-reviewed quality document like the Supplement Reference Guide (SRG) or have trained professionals like yourself properly integrating products with diet, medical history, or other supplements so that when combined EVERY nutrient/ingredient falls within the safe optimal range? The answer is no, so the difference is science versus marketing, and you just have to hope science wins by recommending the products which are delivered and supported only by professionals and not sold in the mass market or through friends. When you are convincing a client about your products versus others, you simply make it clear that this is YOUR program and the only products you trust so that you can guarantee the results including safety (also refer them to the SRG and ask if their product has the same full disclosure). State: "So as long as you are working with me, this is what you will use. When you are finished with me you can do as you please".
Here is more info on those products:
Protandim:
A patented dietary supplement marketed by LifeVantage Corporation, a MLM company. The manufacturers claim the product can indirectly increase antioxidant activity by up-regulating antioxidant factors such as the enzymes superoxide dismutase (SOD), catalase, and the glutathione. Product use would offset the ageing process, potentially allowing people to live up to the age of 120. A review by of eight peer-reviewed studies found insufficient evidence to support the value, safety or efficacy of Protandim. By comparison, the dotFIT SuperiorAntioxidant has complete ingredient and dosage scientific support. Click here for the SRG and see pages 40-47 www.dotFIT.com/SRG.
Juice Plus:
Studies of Juice Plus's effects have generated conflicting and controversial results. Although Juice Plus claims its products' efficacy is backed by research, critics have argued that there is no scientific proof that Juice Plus offers significant health benefits and that deceptive claims are used in the product's marketing information. Some marketing claims made about Juice Plus products have been disputed by consumer watchdog organizations and governmental agencies as misleading. Juice Plus claims that it is “the next best thing to eating fruits and vegetables”, containing the “nutritional essence of 17 different fruits, vegetables, and grains” with key phytonutrients, and that the product is absorbed by the body, reduces oxidative stress, promotes cardiovascular wellness, supports a healthy immune system, and helps protect DNA. Multiple studies have produced conflicting results as to the truth of these claims. The product has been criticized by leading authorities such as University of California Berkeley and Center for Science in the Public Interest on the basis that its marketing is unsupported by research data, it contains too little fruit and vegetable powder to offer significant clinical benefits, its effects can be attributed to the inclusion of added vitamins and micronutrients, and it is excessively priced relative to its potential benefits. Memorial Sloan-Kettering Cancer Clinic referred to Juice Plus as a “pricey supplement” that is “distributed through a multi-tiered marketing scheme with exaggerated value and cost."
Manufacturing: the main ingredients in Juice Plus Orchard Blend and Garden Blend capsules (vegetable and fruit juices, fibers, plant enzymes, and food actives) are reduced to powder and then they add β-carotene, ascorbic acid, vitamin E, and folic acid, and then blend and encapsulate all ingredients. Third party testing by Consumer Labs in 2011 found Juice Plus did not meet their label claims.
