A study published in the journal Drug Testing and Analysis has found that several famous diet drugs and sports supplements might contain a harmful amphetamine type substance, Reuters reported. At present, the health risks associated with the substance are not known because it has not been tested on humans so far.
The substance is known as beta-methylphenylethylamine (BMPEA) and it can be found in dietary supplements that advertise Acacia rigidula as an active ingredient. The supplements claim to aid sharpen attention, boost energy and aid weight loss. A shrub type plant, Acacia rigidula is found in Texas. BMPEA can only be made synthetically.
In 2013, the Food and Drug Administration found BMPEA in supplements but did not warn customers or mention the findings. The study authors said that the FDA should instantly warn people about BMPEA and take an appropriate action to remove BMPEA from dietary supplements. Doctors should remain vigilant for people presenting with toxicity from weight-loss supplements and sports supplements as they might contain BMPEA.
Some companies that manufacture supplements have pulled products from their shelves that could contain the BMPEA. Generally, supplement companies do not need FDA approval to sell their products.
While research about the effects of BMPEA on humans has not been done, there have been studies done on animals. Researchers have found that BMPEA has the ability to raise heart rate and blood pressure.
In 2004, the FDA banned Ephedra after reviewing the effectiveness and safety of the stimulant. Ephedra was found to be associated with psychiatric problems, seizures, heart palpitations, heart attacks and fatal strokes, according to WebMD.
