The hydrochloride and citrate salts of DMBA has been identified as unapproved ingredients in some over-the-counter dietary supplements,[2][3][4] in which it is used in an apparent attempt to circumvent bans on methylhexanamine.[5] The U.S. Food and Drug Administration (FDA) considers any dietary supplement containing DMBA to be "adulterated".[6] Despite the FDA's opposition, DMBA continues to be sold in the US.[7]

There are no known human safety studies on DMBA and its health effects are entirely unknown.[2][3][8]
