This is easily the best oral rehydration packet I've tried for my POTS/nOH, especially when the GI symptoms are flaring. It's an absolute necessity for me to keep this around, otherwise I'd be getting IV hydration much more often. Like many dysautonomia patients, I have a handful of other issues that make my digestive system extra picky, and this ingredient list works well for me, I keep coming back to it. Sometimes I might have 1-2 packets per day, other times less frequently, but I never want to run out. I actually kind of like the taste, and find it soothing.
