C4® is one of America's fastest-growing high performance energy drink companies because each energy drink that they have created contains ingredients which when combined, have been proven to lead to sustained energy boosts. Some of the most common ingredients in their energy drinks include caffeine, Beta-Alanine, L-Citrulline, and N-Acetyl-L-Tyrosine.

The company has targeted specific flavor profiles to give its Electric Sour the right pucker and Peach Mango Nectar the perfect lightness on your taste buds. In every round of development, C4 considers the finish, mouthfeel and texture, and overall drinkability of their flavors.
