Each 16-ounce serving of Pursuit Energy has about the same amount of caffeine as two cups of coffee. Additionally, Pursuit Energy’s blend of B vitamins, Inositol (a naturally derived type of carbohydrate), and Taurine (an amino acid your body naturally produces) work together with the stimulating effect of the caffeine to heighten awareness and focus by improving blood flow, oxygenation, and nerve communication within the body. Multiple flavors are available.
