These are my new go-to electrolyte replacement solution. I used them in conjunction with Saltstick pills on a 9 day TRT thru-hike. Prior to that hike I had always had evening headaches and sometimes miserable knee cramps after multiple day trips with heavy exertion, no matter how much water I drank. On the TRT, I had neither. I can't say for sure how much of it was the Nuun and how much of it was the Saltsticks that I supplemented them with, but the two worked great together. They kept bonks to a minimum as well, despite a pretty heavy hiking pace (at least for me).
Here is how they work. You add a tab to 16oz of water. They have a pre-cut center line so they can be snapped in half to fit each half in the top of a soda bottle or platypus bottle. Each tab has 360mg of sodium and 100mg of potassium, and zero sugar. They are slightly fizzy, and dissolve quickly, like an alka seltzer. Let them dissolve most of the way before putting the cap back on your bottle so that pressure from the fizziness does not build up. They come in several flavors, all of which taste fine (to me). The flavors are understated. Orange ginger is my current favorite. Unlike powder mixes, there is no mess and no clumping. They come in hard-side tubes that protect them from crumbling. Each tab has less than 6 calories, so these are pure electrolyte replacement, and not a dietary supplement, but I prefer it that way because most of the high-calorie drink mixes have lots of sugar.
They are available at Zombie Runner and REI, among other places.
