The U.S. Food and Drug Administration (FDA) announced in 2021 that N-acetylcysteine (NAC) was excluded from the definition of a dietary supplement under the FD&C Act.

The compound, also known as octodrine, is claimed by marketers to enhance energy, focus, and athletic performance. However, its safety and efficacy for oral consumption are not supported by scientific evidence.
