Beet Fuel is a standardized beetroot concentrate. A part the beetroot is replaced by spinach. This is also a natural rich source of nitrates but has a more delicate flavour. Together with the natural apple aroma, Beet Fuel has a softer, more delicate flavour. The 50 ml bottles are a lot easier to drink because of this. The nitrate in these vegetables is converted into nitrogen oxide (NO). This creates a vasodilation and thus a better transportation of oxygen throughout the whole body.
