Rating (out of 5): 2
Ephedra, also known as Ma Huang, has been used historically in traditional Chinese medicine for respiratory issues but gained prominence in the late 20th century as an ingredient in dietary supplements marketed to athletes for weight loss and improved exercise performance. The scientific rationale behind its use in athletic and exercise aids stems from its content of ephedrine alkaloids, which are central nervous system stimulants. Several studies have demonstrated that ephedrine, especially when combined with caffeine, can produce modest increases in short-term physical performance, alertness, and energy expenditure, as well as small enhancements in weight loss and fat oxidation.
However, the evidence base is limited in both quality and duration; most studies are short-term and involve small sample sizes. The potential benefits in athletic performance are modest and mostly observed in endurance activities rather than strength or high-intensity exercise. Importantly, ephedra and its alkaloids have been associated with severe adverse effects, including hypertension, arrhythmias, stroke, and even death, which led to a ban on ephedra-containing supplements by the U.S. FDA in 2004. Thus, while there is some scientific evidence supporting its effectiveness as an athletic aid, the risks far outweigh the benefits, and its use is generally not recommended or permitted in sports settings.
