The labeling of a dietary supplement includes the statement “promotes weight loss.” The dietary supplement contains various vitamins and minerals and a botanical extract. The manufacturer relies on a randomized controlled double blind clinical study showing that subjects who took the botanical extract had a small but significant increase in metabolism over subjects taking a placebo over a 24 hour period. The study did not examine the effect of the extract on subjects’ weight and there is no research showing that a short term increase in metabolism will translate into any measurable weight loss. The weight loss claim would likely not be adequately substantiated.
