My go-to for electrolytes is Zico coconut water. LOVE it. Excellent for when you're sick, too. Also super for hangovers haha.
My second option is Emergen-C. I always keep spare packets with me to easily add to a bottle of water. I've been using that for years but prefer Zico of the two.
EDIT: I use the "natural" flavored Zico for the liquid base in my protein shakes, too. Awesome.
