While I still don't feel like I understand electrolytes as well as I would like to, I become more convinced that supplementing potassium when one engages in activities that produce sweating is worthwhile.
Over the last year I started using potassium carbonate like a spice and whether or not it feels tasty depends a lot on how much I was sweating in the day before the meal.
Giving that summer comes up, if you aren't already supplementing electrolytes for those days that are warm enough to make you sweat, I recommend you to get some potassium carbonate and experiment with it. It's worth noting that you need relatively tiny amounts, so if you start experimenting with it start really low as it's easy too put too much into the food and make the food taste bad.
Supplementing sweat out electrolytes seem to reduce the feeling of being drained from the summer heat.
That's certainly also an option. I personally found for myself, that I feel intuitively less drawn to NaCl+KCl than to NaCl + K2CO3 (I have both at home).
Most supplements that have mixes of electrolytes don't seem to use KCl and so would give you relatively less chloride than the NaCl+KCl mix.
In addition to that from my perspective, I think that if every day of the year you consume the same amount of potassium you (as a typical office worker) likely consume either too much or too little on some days.
