The compound is an aliphatic amine. DMBA has been identified as an unapproved ingredient in some over-the-counter dietary supplements, in which it is used in an apparent attempt to avoid laws prohibiting the use of methylhexanamine. The U.S. Food and Drug Administration (FDA) considers any dietary supplement containing DMBA to be 'adulterated'. Despite the FDA warning, DMBA continues to be found in weight loss supplements sold in the US. There are no known human safety studies on DMBA and its health effects are entirely unknown.
