How does the country stipulate weakly alkaline water and what is the PH value to be considered weakly alkaline? Please master the advice!

Weak alkaline water, there is no national standard at present, only industry standard.

PH 7 is neutral, below 7 is acidic, above 7 below 8.5 is weakly alkaline, and above 9.5 is strongly alkaline.

The recommended value of drinking weakly alkaline water is around 8-8.5, and drinking alkaline water above 8.5 should be under the guidance of a doctor.

Note that all kinds of alkaline water cups or micro-electrolytic water cups are purely bluffing.
