If you don't have access to PristineHydro water, we recommend using the best (clean, high pH) water you can find. If you don't have a carbonation machine, you'll want to pick one up; some excellent soda machine options here (i.e., SodaStream). A great quick solution is buying a box of sparkling mineral water; the site VeryWellFit has an excellent review of sparkling water options based on quality and pricing. Note: It is not necessary to use a carbonation machine or sparkling water with our liquid Electrolyte Balance.
