electrolytes

I’m looking to take some supplements for hiking. I already include some sugar pills and I got some protein bars that I take with me but what are some other supplements that you’d recommend I take as a hike or should I take some electrolytes in case I get dehydrated? I will be hiking out west and...

should I be taking electrolytes in during the day or should I just stick to water. I'm not a person who sweats very often but I do live in a very hot climate that I just moved to and I noticed that I get hot a lot easier now. Is it important to use electrolytes to keep me going
