DMAA is a common ingredient in many supplements promising weight loss, muscle building and performance enhancement. However, it is associated with side effects like high blood pressure leading to heart disease including heart attack, shortness of breath and tightening of chest.
Following the 86 reports of illnesses and death associated with supplements containing DMAA received, FDA has warned the companies using DMAA as an ingredient in their products that the products containing the stimulant are illegal.
All companies except USPLabs have agreed to stop using DMAA. USPLabs had responded by providing study reports challenging FDA's decision. According to FDA, the data is not sufficient to justify the use of DMAA as a safe ingredient in dietary supplements.
FDA has urged people to consult their physician before taking a supplement and to avoid products containing DMAA, which is listed in product labels by ten different names. FDA has also asked people to report any health problems associated with supplement intake to the company or the agency.
