If you can't find "Soda Water" that is suitable, then you may buy just plain carbonated water.

Ways to Take Your Homemade Magnesium Supplement:
Flavored: We add it to juice around here all the time. It can alter the color somewhat so be warned. –Heather
In your daily water: I have a 2L bottle and about ⅓ of it is the concentrate, at this point that seems to be what I need. –Beppy Jo
We just drink it straight from the bottle. –Judi
Other ideas for flavor: We add a bit of liquid sweetleaf stevia flavoring to it, add lemon juice, or a packet of Emergen C (it gets REALLY fizzy!) –Gwen
