minutes you get a drink that tastes refreshing and light. There is merely a hint of flavor, and it also does not overpower water's thirst-quenching natural state.The nuun tabs have 360mg of sodium apiece as well as three other electrolytes, potassium, magnesium and calcium. There is no sugar, no caffeine, and little else in nuun, which takes the most minimalist approach to the product in the fizz-and-drink category.ZYM sets itself apart from nuun by adding B vitamins and, for its ZYM Catapult product, 100mg of caffeinated drinks. I get a bigger immediate boost from ZYM than nuun. Its taste in either of you're able to send two flavors (berry and lemon-lime), is stronger, too.CamelBak's Elixir, another sugar-free pill, costs about $10 for a tube of 12 tablets. This is more money than the competition, but Elixir is more focused and goes somewhat further. Each CamleBak tablet works for up to 24 ounces of water. I actually often use them in a 16-ounce bike normal water bottle, and the taste is noticeably stronger than nuun or ZYM.Pocima, like the other companies' options, is not hard to imbibe. It comes in orange, lemon-lime, and berry flavors. All are good-tasting and refreshing.
