1,3-DMBA is a chemical with stimulant effects that's found in small amounts in some plants. But the 1,3-DMBA found in supplements might be made in a lab.
1,3-DMBA causes blood vessels to contract, which increases blood pressure and speeds up the heart.
People use 1,3-DMBA for athletic performance, memory and thinking skills, obesity, and other conditions, but there is no good scientific evidence to support these uses. 1,3-DMBA might also be unsafe.
The US FDA banned the use of 1,3-DMBA in dietary supplements in 2015, but it's still found in some products. The 1,3-DMBA found in supplements is most likely made in a lab, since plants contain only very small amounts of this chemical. 1,3-DMBA is on the World Anti-Doping Agency's (WADA) prohibited substances list. Don't confuse 1,3-DMBA with 1,3-DMAA, 1,4-DMAA, or Dimethylhexylamine (DMHA). These are not the same.
