How much caffeine is in each can and where does it come from?

What other active ingredients support focus and mental performance?

C4 Smart Energy includes Cognizin citicoline, an ingredient commonly used to support cognitive processes like focus and attention. The beverage combines this with caffeine to address both alertness and mental clarity. Ingredients are chosen to complement each other rather than relying on sugar or high-calorie stimulants.

• Cognizin citicoline for cognitive support
