The main ones I take are Calcium, Magnesium (important for preventing cramps, and also helps with brain signalling), Potassium, and Sodium.

Almost any of the supplements you might want are available in powder form, so if you prefer mixing up a drink instead of taking pills, that’s an option. Search Amazon for “bulk [supplement name]” and you should find options.
