More than one in seven American adults have used nonprescription dietary supplements to try to lose weight, as per scientists at the U.S. Centers for Disease Control.

Nearly 9,500 people over age 18 were asked about the prevalence and duration of nonprescription weight-loss supplement use, associated weight-control behaviors, discussion of use with a health-care professional and specific ingredient use.

Approximately 15 percent of the respondents said they had used weight-loss supplements, and 8.7 percent said they had done so in the past year. The highest use was among women 18 to 34 years old (16.7 percent). Nearly three-fourths of respondents (73.8 percent) said they have used a supplement containing a stimulant including ephedra, caffeine and/or bitter orange.

The scientists conclude: Qualified professionals should inquire about use of supplements for weight loss to facilitate discussion about the lack of efficacy data, possible adverse effects, as well as dispel misinformation that may interfere with sound weight-management practices.
