Mandatory Disclaimers on Dietary Supplements Do Not Reliably Communicate the Intended Issues

In this systemic review of dietary supplement disclaimer studies, larger and more rigorous studies revealed that many consumers were unaware of disclaimers or that they did not affect patient perceptions of supplements. These findings suggest that relying on disclaimers as an alternative to government restrictions on drug marketing would be inadequate for informing patients about drug efficacy and safety, and risk enabling a return to problematic levels of inappropriate prescription drug use.
