pH: The logarithmic value of the reciprocal of the hydrogen ion activity in water. The World Health Organization does not yet have a health-based guideline value for pH. Of course, the closer the pH of water is to blood pH, that is, 7.35 to 7.45, the best.
However, in human evolution, from drinking natural water, well water to tap water in the past 100 years, the pH is between
6.5-8.5. Therefore, as long as it is within this range, the human body has strong pH buffering and adjustment capabilities.
Standard pH 6.5-8.5.
