FDA Warns Dietary Supplements Marketers to Stop Deceptive Claims

In a letter sent to dietary supplement manufacturers this week, the Food and Drug Administration addressed escalating concerns about undeclared or deceptively labeled ingredients in products marketed as "natural" alternatives to prescription drugs. The letter comes after nearly 300 consumer alerts and numerous consumer complaints of injury associated with the substances.

A string of recalls due to marketers' failure to disclose dangerous ingredients, which can be harmful when taken in combination with other drugs, have highlighted the risks to consumers seeking alternative treatments that claim prescription-strength results.
