Nuun:electrolyte enhanced drink tablets. My new favorite electrolyte drink. One tube comes with twelve tablets, one tablet per 16oz of water. Each tablet is scored, and they break easily enough to place in an 8oz bottle. My favorite flavor so far is pink lemonade. Today I tried the tropical flavor and it was just as good. Nuun tablets come in 11+ flavors and “turns water into a refreshing sports hydration drink without the sugar” The drink is refreshing and has a seltzer quality to it. Try it out!
