N2 was formulated specifically to enhance blood circulation. In fact, the skin flushing and tingling sensations you get minutes after drinking N2 is a sign of oxygenated blood getting pushed into capillaries that don't normally get as much blood-flow.By combining the two formulas, you are essentially using your N2-supercharged blood circulation to transport the nutrient and enzyme-rich contents of N1 to parts of your body that otherwise wouldn't receive that nourishment.
