Breathable Foods has said it will fully cooperate with the Food and Drug Administration (FDA) over its investigation into the firm's caffeine shot launched last year.

AeroShot Pure Energy, an inhalable caffeine product that is breathed in as a powder and deposited as a liquid on the tongue, was launched in the US last month. However, FDA officials are investigating whether the product is safe for consumers, a spokesperson for the watchdog told just-drinks today (29 February).

He said: "We will consider whether a violation of the Federal Food, Drug, and Cosmetic Act has occurred and, if so, whether regulatory action is warranted in light of FDA's enforcement priorities and resources." The spokesperson declined to comment further.

Breathable Foods said: "We will cooperate fully with the FDA's review [and] are confident that it will conclude that AeroShot is a safe."
