IN-light stimulates the mitochondria, the energy factories in every cell, which increases energy production. The great thing is that the more you exercise, the more mitochondria are created in your body. And these energy factories also charge you up to maximum power in a completely natural way. Isn't that what you want too? Not by creating more red blood cells, as with doping, but by optimising the red blood cells you already have. You also become less acidic, your circulation improves, there is a positive oxygen effect in the body and you ensure that nutrients are better absorbed in all cells. Who wouldn't want that?
