The nature of the pH scale means that even small shifts represent a large change within the acidity or alkalinity of your blood. How so? For example, if your blood pH were to fluctuate from 7.4 down to 6.4, this actually means that the concentration of hydrogen ions within your blood has gone up by a factor of ten (4). This is astonishing, and it clearly shows why keeping your blood within a strict pH range is such a priority to your body. In fact, your body will rob minerals from cells, organs and even bones in order to keep your blood pH within acceptable limits. Lanlang’s alkaline filter can increase the PH level to 8.5+.
