Stimulants in dietary supplements – when one is banned, another takes its place
In a study published last week, researchers at Harvard University examined 21 brands of dietary supplements containing an herbal stimulant called Acacia rigidula. More than half of the brands analyzed contained an untested amphetamine isomer called β-methylphenylethylamine (BMPEA).
The supplements were marketed to help people lose weight and to enhance energy. Even though BMPEA was first synthesized in the early 1930s, it is relatively unstudied. Because studies of safety and efficacy in humans have not been performed, its unknown whether it is dangerous. It appears that BMPEA is intentionally added to these supplements for its stimulant properties and since it is not listed on the…

After Ephedra, More Supplements Targeted for Ban

Ephedra Is It Worth the Risk?
The herb ephedra, also known as ma huang, is a small, twiggy shrub native to Asia, where it has a long history of medicinal use, as documented in ancient medical treatises from India and China.

Stimulants in dietary supplements – when one is banned, another takes its place
The story about synthetic stimulants popping up in dietary supplements is not new. A little over a decade ago the major dietary supplement of concern in the US was ephedrine (an alkaloid found in ephedra). Ephedrine was widely used for weight loss and performance enhancement (although it also has approved medical applications).

Ephedra is a low evergreen shrub with small scaly leaves. It has a long history of medicinal use in China and India to treat colds, fever, headaches, coughing, wheezing, and other conditions. The U.S. Food and Drug Administration (FDA) banned the sale of dietary supplements containing ephedrine alkaloids (stimulant compounds found in Ephedra sinica and some other plants) in the United States in 2004. Prior to the ban, ephedra was an ingredient in some dietary supplements promoted for weight loss, increased energy, and enhanced athletic performance.
