This innovative combination of caffeine (150mg) and green tea extract, paired with freshly pressed fruits and a kick of cayenne is the perfect natural energy boost. Recent research has shown that caffeine combined with L-theanine is able to enhance focus, attention and energy more effectively than caffeine alone. Regular caffeine intake is often associated with anxiety, increased heart rate and blood pressure. This natural combination helps to avoid these issues to deliver smooth, sustained energy. Capsaicin found in cayenne pepper is also known to enhance energy and help you fight fatigue. Drink in the morning or 30-minutes before your workout.
