The problem of water life

The normal PH value of human blood is between 7.35 and 7.45. Only Nongfu Spring meets this standard, while others fail to meet it. The water production should be in the range of 8.0-9.5, which is weakly alkaline. Slightly higher than the normal value of the human body to neutralize acidosis in the body. Return to normal ph. Strong alkali is probably not drinkable, but can't it be diluted before drinking? By the way, is yours genuine?
