Kinda. From the CVS website:

Vitamin B6, Vitamin B12, Vitamin B3 (Niacin), Citicoline, Tyrosine, Phenylalanine, Taurine, Malic Acid, Glucuronolactone, Caffeine. Other Ingredients: Purified Water; Natural and Artificial Flavors; Sucralose; Potassium Sorbate, Sodium Benzoate and EDTA.

So, Caffeine for sure. But the b-complex, and Taurine will also give you a boost, for entirely different reasons. Half this stuff is psuedo-scientific at best, and the rest just filler.
