Dozens of weight loss and immune system supplements on the market are illegally labeled and lack the recommended scientific evidence to back up their purported health claims.

A report released on Wednesday by the Department of Health and Human Resources claims investigators found that 20 percent of the 127 weight loss and immune-boosting supplements purchased online and in retail stores across the country carried labels that made illegal claims to cure or treat disease.

Some products went so far as to state that the supplements could cure or prevent diabetes or cancer, or that they could help people with HIV or AIDS, which is strictly prohibited under federal law.
