In the wake of the recent warning letters issued by the FDA, several dietary supplement manufacturers of DMAA are responding to the negative attention.
One company MuscleMeds, which produces the popular pre-workout supplement Code Red, deleted the product from its Web site. A receptionist was informing consumers that the product was being reformulated.
A Web page for Fahrenheit Nutrition, another one of the 10 companies that received the FDA letter, reflected that its Lean EFX product no longer had DMAA on the nutritional label. A man answering the phone at the number given on the company’s Web site said he couldn’t comment.
The FDA warning letters have already prompted retailers, such as Amazon, to stop carrying the DMAA products. They are going to still, however, allow third party vendors to do so.
Yet, one company does not agree with the FDA warnings, and is disputing that the agency has not cited medical or scientific evidence showing that DMAA us unsafe. The company owns the GNC health and wellness stores. They are disputing a recent U.S. Food & Drug Administration’s (FDA) warning questioning the safety of DMAA dietary supplements. In a statement just issued, GNC asserted that the agency has not cited medical or scientific evidence showing that DMAA is unsafe. The company maintains that, when used as directed, DMAA supplements have “the same effect on the body as drinking two cups of coffee.”
According to the FDA, DMAA can narrow the blood vessels and arteries, which can elevate blood pressure and may lead to cardiovascular events ranging from shortness of breath and tightening in the chest, to heart attack, according to the agency. The FDA said it had received had received 42 adverse reports on products containing DMAA, including psychiatric disorders and death.
