DMAA (dimethylamylamine) is an ingredient in multiple bodybuilding, fitness, energy, and weight loss supplements. DMAA is a stimulant which has been linked to heart attack, stroke, kidney failure, liver failure, and death.

DMAA Dangers

  • Liver failure

DMAA was originally intended to be used in nasal decongestants. It is now used in bodybuilding supplements for its stimulant effects. In weight loss supplements it is said to help burn fat and suppress appetite.

DMAA is also used recreationally for its stimulant and euphoric effects, and is often referred to as a “party drug”.

Not So Natural

DMAA is marketed as a “natural” ingredient derived from the geranium plant. However, there is controversy about that claim alone. A recent study, published in the Journal of Analytical Toxicology,found that there was no DMAA in geranium, but that products that listed geranium oil or extract contained large amount of DMAA.

This has important legal implications regarding how DMAA is classified as an ingredient and the way it is regulated.
