How much caffeine is in Protein Coffee?

Protein coffee blends a cup of coffee with protein powder, so the caffeine, about 95 mg, comes from the coffee base alone. The protein adds substance for a post-workout or breakfast drink without changing the caffeine.

Coffee blended with protein; caffeine from the coffee base (~1 cup).

Will Protein Coffee affect your sleep?

At 95 mg, protein coffee takes roughly five hours to fall under 50 mg, just like the cup of coffee inside it. A morning one is well clear by night; an afternoon version may still register.
