Nuun Hydration: Electrolyte + Caffeine Drink Tablets, Mango Orange, Box of 8 Tubes (80 servings), Performance Formula with A Kick

I love Nuun and recommend it, but I ordered an 8-pack, sold by Amazon, and two tubes were partly opened. I opened one of the fully-sealed tubes, and the tablets look like they were exposed to heat or moisture. They are usable, but I think it can affect how well they dissolve.

I buy this for my husband a lot. He loves it because one he likes the taste and the flavor for this particular one. It has caffeine to help boost his drive when he is cycling 365 days a year. Easy to mix, great effectiveness especially when he does Ragbrai and other sporting events. Just wish it didn't cost so much but it works for him.

Shipped fast and in good condition. Mango is by far my favorite flavor.

Great deal for a big supply of Nuun! Think ahead and get one of these of you lead an active lifestyle!

I really like these electrolyte tablets. I bought them for strenuous swim training, knowing I needed electrolyte replacement but wanting to minimize the sugary sports drinks that upset my stomach. I appreciate that these have a little bit of caffeine in them to give me just a bit of a kick. Additionally, they are slightly fizzy, which I like. I also like that these have B vitamins in addition to the electrolytes. One small word of caution and the reason for 4 rather than 5 stars...if you drink more than two at a time or if you're prone to gas/bloating while working out, the fizz can be a bit counterproductive. For my longer swims (3+ hours), I switched to using Skratch products, which have a slightly higher electrolyte concentration and no fizz because I started having some stomach troubles (primarily caused by other issues, but the fizz didn't help). I still use these during my morning lift/swim sessions (90 mins total), though, and really love them!
