Juice Plus - Product Research

Product Research

National Safety Associates, the owner of Juice Plus, claim 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. Doubts have been raised about the advertised benefits of Juice Plus by Memorial Sloan-Kettering Cancer Center, University of California Berkeley, Center for Science in the Public Interest, and other sources. The product has been criticized 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 exogenous 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."

Of the published peer-reviewed studies on Juice Plus products, the majority were funded and/or authored by the manufacturer, Natural Alternatives International (NAI); or the main distributor, NSA.; two were funded by individual Juice Plus distributors; and one was conducted independently.
