The Efficacy of Weight-Loss Supplements 

Are there any safe and effective dietary supplements for weight loss?

Past investigations have revealed that many commercial herbal supplements do not contain the listed herbs, instead being filled with cheap alternatives like rice, asparagus, and houseplants. Weight-loss supplements are often contaminated with prescription and over-the-counter drugs, with some even containing antidepressants and erectile dysfunction medications. Illegal adulterants, such as sibutramine, have been found in a third of weight-loss supplements, leading to serious health risks. Despite FDA recalls, many tainted supplements reappear on store shelves, as manufacturers prioritize profits over compliance.

There is little evidence to support the effectiveness of weight-loss supplements, as trials have shown that they do not outperform placebo sugar pills. Instead, experts recommend focusing on a diet rich in whole plant foods and low in animal products and processed foods for safe and sustainable weight loss. It is important to be cautious when considering supplements for weight loss, as many contain harmful or banned substances that can pose serious health risks.
