While Revive Brain+ is formulated to boost focus without using caffeine, there’s no clear research proving it’s either harmful or beneficial to combine the two. Some people still choose to pair them, but if you do, it’s smart to begin with a small amount of caffeine and see how your body responds.
You might also be asking, why do some energy drinks include citicoline? This nutrient is known for supporting memory, mental clarity, and sustained focus. In energy drinks, citicoline can work alongside caffeine; caffeine gives the quick jolt of alertness, while citicoline helps maintain cognitive performance for longer. Together, they can provide both an immediate boost and ongoing mental support.
