I like the watermelon flavor a lot. I tried the lemon-lime and found out it didn't agree with me. I'd suggest trying just one bottle of tablets directly from a store first, if you can. Flavors are so specific to a person that what one person likes, another hates. Happy to find these in boxes of 4 on Amazon. These are a basic electrolyte with a bare minimum of sugar and no caffeine. They work well for me on heavy workouts and longer runs. The price is right - not as expensive as some other more highly advertised brands. These also work for me when traveling. I break a couple of tablets in half and use half in my water bottle on very long flights. The tablets are a lot easier to pack than powders. Less messy. No TSA issues. Perfect for keeping up with my running or gym workouts on vacation. Read more

My dr recommended NUUN because I have been having severe leg craps at night. I am about to start my 3rd tube, and I have not had a serious cramp since I started. I now drink it in cold water every night before bed. Read more

I’ve been using Nuun Sport Electrolyte Tablets during my workouts, and they’ve made a noticeable difference in my hydration and endurance. The watermelon flavor is light and natural, not overly sweet, which makes it easy to drink throughout my sessions. I appreciate that they’re low in sugar and free from artificial additives, aligning well with my health goals. The tablets dissolve quickly in water, creating a slightly fizzy drink that’s both refreshing and effective. Overall, a great addition to my fitness routine. Read more

Love these. Great flavor and good electrolyte profile Read more

Nuun packets work great for me in the hot Texas summer months because I can drop a half tablet in a normal water bottle for a lighter taste, or 2 in my Stanley, or anywhere in between depending on how much I need. Whereas with hydration packets, it's messy if I try to save a half of a bag when I need just 0.5 or 1.5 for a larger water bottle - Nuun is more convenient and transportable in my tennis bag. I also find myself drinking more water when I have Nuun in it because I like the taste, especially watermelon. Read more

Has the unfortunate mouth feel of magnesium citrate but not a terrible taste. Bonus points for the medium mg size. 5 out of 5 Read more

I use these in my handheld, from 10k's up to marathons distances. I like the watermelon flavor the best because it only has a subtle, light flavor, not overpowering, and still tastes OK even when the water gets warm. Read more
