A dietary supplement marketed to allow coffee consumption at night without side effects has unknown safety.

What it means

This Scientific American article reports on a dietary supplement marketed to allow drinking coffee at night without the usual side effects, such as sleep disruption. The supplement's active ingredient is likely theacrine, a compound structurally similar to caffeine but claimed to have a different balance of effects. However, no regulatory body has evaluated its safety, and there is no robust clinical evidence backing the claims, leaving potential risks unknown.

Accuracy & sourcesGrounded

The claim is based on a Scientific American news article that synthesizes information from supplement marketers and anecdotal reports; it does not cite a primary scientific study or regulatory assessment. As an aggregated/secondary source with no primary cited, the article itself does not verify the safety or efficacy of the supplement, so the solidity of the claim is low—it is essentially reporting on unsubstantiated marketing.
