(CNN) -- Food and Drug Administration officials plan to investigate whether a form of caffeine sold in lipstick-shaped containers is safe for consumers.

The inventor touts AeroShot as caffeine without the coffee, soda, tea or a pill, but a U.S. lawmaker questions whether it's safe.

The product comes in a lipstick-shaped dispenser that puffs out a powdery mixture of caffeine and B vitamins into your mouth, where it dissolves and is swallowed.
