This problem bothers me all the time, especially since my home is in a hot climate. I've tried several methods but none satisfy me completely. One mix stands out for its flavor and includes sodium along with potassium and magnesium while keeping sugar minimal. Yet the sodium level seems insufficient for recovery after physical activity, making it suitable mainly for regular days. Another provides a nice ratio of sodium to potassium with little sugar, though it lacks magnesium and costs more than others. Its taste appeals to me most. A third includes vitamins plus minerals and works for daily use rather than intense sessions, but it's difficult to locate locally and has smaller amounts of potassium and magnesium. Tablets from one brand upset my stomach. For exercise I mix maple syrup with sea salt from the store which saves money but makes precise dosing tricky. This gives me sodium and energy but isn't a full electrolyte balance. Keeping fluids in check stays challenging. I'll discuss this with my physician soon.
After my operation a couple years back I don't take in fluids the way I once did so dehydration hits me often. To keep my kidneys from getting strained I've mixed up my own electrolyte blend. Even though I've looked into the topic quite a bit I'm still hoping to find other approaches. My blend uses two quarts of water plus potassium magnesium a mineral salt sugar-free taste packets I've tried in different varieties and just a tiny bit of unrefined raw sugar. What blends does everyone else rely on to stay hydrated? Strong stevia leaves an unpleasant sharp aftertaste for me so the little bit of raw sugar helps cut that edge.
