Flavoured hydration powders are a solid option, as long as you’re avoiding chemical sweeteners.
The trick is to make them at half the recommended strength by putting the recommended amount into double the volume of water, which will also stop you from giving yourself kidney stones by overloading you with minerals






Things like Acesulfame K, Aspartame, Steviol/Stevia extracts, I called them chemical sweeteners where it would be more accurate to call them artifical sweeteners.
It’s entirely anecdotal, but all of these leave a horrendous taste that overpowers the intended flavours in my opinion.
Sucralose is probably the only one that works as intended (massive sweetness to replace sugars at a fraction of the volume)
