Banned ingredients in Supplement for Muscle Building

DMAA is often touted as a “natural” stimulant, with many claimed functional uses including a body-building aid, an athletic performance enhancer, and a weight-loss aid. Although DMAA at one time was approved as a drug for nasal de-congestion  no medical use of DMAA is recognized today. FDA is not aware of any reliable science indicating that DMAA exists naturally in plants.

This substance narrows blood vessels and arteries, which can elevate blood pressure, and may lead to cardiovascular problems such as shortness of breath, arrhythmias, tightening in the chest, and heart attack, as well as seizures and other neurological and psychological conditions. FDA has received 86 reports of adverse events involving products containing DMAA. These events include psychiatric disorders, heart problems, nervous system disorders, and death. 

FDA sent warning letters to a total of 11 companies advising them that DMAA-containing products marketed as dietary supplements are illegal.
