Not exactly what you're looking for, but Wake water has a couple powdered zero sugar electrolyte (and energy) drink mixes, and Roar has some low sugar berry lemonade hydration/antioxidant powders.

I have been in the market for a good water bottle/canteen/tumbler and these look like a great option! Thanks for sharing!

I haven't bought from here yet, but this company looks promising!

If it's the one at the Lawson mall its at the back and to the right from the entrance, behind the hair and stationary supplies, I think.
