The combination of Green Tea Caffeine and L-Theanine work together synergistically to provide sustained energy levels lasting up to several hours. In addition, Vitamin B12 has been added as it helps you stay energized physically and mentally with its essential role in converting carbohydrates into glucose — the fuel your body needs for energy. Furthermore, our strips are carefully embedded with nutrients that can be absorbed directly into your mouth, skipping digestion time in your stomach. This natural combination of caffeine and anxiety-reducing amino acids immediately boost alertness.
