Dietary herbal supplements have gained popularity among individuals looking to lose weight or improve their athletic performance. One such supplement is ephedra, which contains ephedrine, an alkaloid derived from the herbal ephedra plant. This article aims to review the effectiveness and safety of using ephedrine or ephedra as a dietary supplement for weight loss and athletic performance. We will analyze various studies and explore the potential benefits and risks associated with these supplements. (2)


To conduct this review, a comprehensive search was performed on various databases, including MEDLINE, EMBASE, BIOSIS Previews, AMED, MANTIS, the Cochrane Controlled Trials Register, International Pharmaceutical Abstracts, Pascal, and SciSearch. The search included articles published from inception to March and April 2001, with no language restrictions. Grey literature and unpublished studies were also sought through notices in journals and by contacting regulatory bodies and experts. Reports of adverse events were obtained from the U.S. Food and Drug Administration and Metabolife, the manufacturer of ephedra products.

Studies that assessed weight loss, athletic performance, or reported adverse events were included in this review. Randomized controlled trials (RCTs) or controlled clinical trials (CCTs) were eligible for the assessment of efficacy, while case reports were considered for the safety analysis. Validity of controlled trials was assessed using the Jadad scale. Data on study design, participants, therapies, weight loss, follow-up times, and adverse events were extracted. Meta-analyses and narrative summaries were conducted for weight loss and athletic performance, respectively.


Weight Loss

Several trials compared the effects of ephedrine or ephedra on weight loss. The pooled estimate of the rate of weight loss for ephedrine compared to placebo was an effect size of -0.50, equivalent to a monthly weight loss of 1.3 pounds more for ephedrine users. Ephedrine plus caffeine showed even more promising results, with a pooled estimate of -0.85, indicating a weight loss of 2.2 pounds more compared to the placebo group. Ephedrine plus caffeine was also found to be more effective for weight loss than ephedrine alone. Ephedra alone and in combination with caffeine-containing herbs also showed significant weight loss benefits. (1)

Athletic Performance

Limited evidence was available regarding the effects of ephedrine or ephedra on athletic performance. Small trials comparing synthetic ephedrine with or without caffeine to caffeine and placebo did not show significant improvements in athletic performance, except for one trial that found a significant improvement in muscle endurance during strength training.

Adverse Events

The use of ephedrine or ephedra as dietary supplements was associated with higher rates of psychiatric symptoms, autonomic hyperactivity, heart palpitations, and upper gastrointestinal symptoms. These adverse events were observed in both controlled trials and case reports.


The findings of this review suggest that ephedrine or ephedra can provide modest short-term improvements in weight loss. However, it is important to consider the potential risks associated with these dietary supplements. The increased rates of adverse events, such as psychiatric symptoms and cardiovascular effects, should be taken into account when considering the use of ephedrine or ephedra for weight loss or athletic performance enhancement. (3)


In conclusion, ephedrine and ephedra as dietary herbal supplements have shown some effectiveness in promoting weight loss. However, they are also associated with an increased risk of adverse events. Individuals considering the use of these supplements should carefully weigh the potential benefits against the potential risks and consult with a healthcare professional. Further research is needed to better understand the long-term effects and safety profiles of ephedrine and ephedra as dietary supplements.
