Thanks for the replies! Pedialyte is something I've tried in the past. Unfortunately if I recall it also had a lot of sugar which is something I do prefer to avoid as it tends to increase my frequency. Sugary drinks especially on warm days go right through me like water.
I neglected to mention in my first post; I'm ideally looking for something that would be portable that I can take with me for a quick boost when I need it, especially because I am more active than I used to be. Potassium chloride is sold as a salt substitute and can be added to drinks and I'm wondering if that's something I can try, I just wouldn't know how much to use. There are also electrolyte gels and gummies sold for marathon runners/cyclists but again you're dealing with the high sugar issue. I shall continue to investigate!
Pedialyte has very low suger 9g compared to Gatorade which had 34g of sugar. My doc said pedialyte is the closest thing to IV fluids you can get without having to go to ER. I drink a bottle of pedialyte a day.
