This is in stark contrast to the group’s announcement in October 2001 that 60% of nutrition bars tested did not meet their label claims.


Nutrition powders and drinks, often consumed as shakes, are commonly used for dieting, general nutrition, body building and to enhance athletic performance. Annual sales of nutrition powders and drinks grew 16% in the past year to US$971m in traditional US retail channels alone according to Information Resources, Inc. (Chicago, IL).


The two nutrition powders failing to pass ConsumerLab.com’s review contained the herbal ingredient “stevia”, which is a non-sugar sweetener that has not been approved for food use in the US due to inadequate safety data. Stevia can only be sold in the US as a dietary supplement. The two products that contained stevia were labeled as foods, not supplements.


Tod Cooperman, MD, president of ConsumerLab.com commented: “Aside from the two products that should have been labeled as supplements because they contained stevia, the results were a welcome relief from the many problems we recently found with nutrition bars, where the full carbohydrate content was often hidden from consumers.

“The drinks and powders tend to contain about half the amount of carbohydrate and fat as nutrition bars and generally twice the amount of protein per serving. In fact, people using some of these powders and drinks as their primary source of nutrition should make sure that they are getting enough fat and carbohydrate from other foods.”
