There’s a new competition in electrolytes called Body Armor which has more electrolytes plus coconut water ” high in K+” and vitamins.wouldnt recommend for kids though unless they are active or heat involved like soccer.
You can also make your own in less complicated ways using a portion of coconut water ” potassium” in mixed in something like lemonade with some sea salt added and trace mineral drops for magnesium. Bottled water usually filtered out the minerals can leave you depleted.
Maya keep a eye on that cranberry juice sometimes it’s not real plus loaded with things like high fructose corn syrup Gatorade also used to have till pressured out including oil they also took out. Best to make your own with a can of real cranberries or get the tablets. If your going to go that route you have to be aware of your whole diet in general or drink it seperatly between meals. To help lower acidity try drinking water based things before or awhile after means and drink fluids that mix with fat and oils with meals like milk, real juice, what ever.
