I use H3O for oral hygiene purposes. Since it has a pH in the opposite direction, won the H3O interfere with my use of HRx?
If you gargle with H3O (as opposed to drinking it), the effects will be marginal compared to the effects of drinking the HRx (alkaline water). In addition, you are not using them at the same time (and if you didn’t know this, you do now). If you are just using the H3O to brush and/or gargle, and you rinse your mouth out with water afterwards (water being close to neutral), this will not have a significant effect on your intended use of HRx.
