The advertising described him — with incredible chutzpah — as “Widely regarded as the world’s No. 1 nutritionist.” The product here was goji juice, which was promoted as: “The biggest discovery in nutrition in the last 40 years!”

The expert emphatically stated that the many benefits of goji juice had been firmly established in clinical studies on humans. But I was unable to find a single study in the medical literature that reported a clinical trial showing a positive impact on health or disease. Supplements are also marketed by way of infomercials on TV and as junk mail. The level of dishonesty here is at least as bad as the above cases.

In brief, the people carrying out the marketing of supplements often use scientific evidence the way a drunk uses a lamppost: more for support than illumination. Clearly, there is widespread fraud. This also poses a risk to the health of consumers as some consumers may choose supplements of no value over conventional medical treatment. In addition, many supplements, especially herbs, pose a risk of side-effects.
