Treeline Review Katie Gerber · reviewer · May 2026

Our top pick for best electrolyte tablets for hiking and backpacking is Nuun Hydration Sport. The packaging, flavor variety, and ease of use make it the perfect choice when portability is a top concern. Nuun Sport comes in tablets in a tube and in a large variety of flavors (watermelon and cherry limeade are two of our favorites). It’s popular among several Amazon reviewers because of its convenience and effervescence (yup, it’s bubbly like an Alka Seltzer).

I really like these hydration tablets. I use them basically every single day. I normally put one in my water bottle when I go to the gym and I also take my dogs for around a hour and a half walk every day. I really want to make sure I'm replacing all those electrolytes that I'm losing as I'm exercising or as I'm out for a long walk.

Most reviewers say Nuun tastes better than sugary sports drinks and helps them drink more water. The tablets are portable, low in sugar at ~1g per tablet, and come in flavors like strawberry lemonade, lemon lime, and tri-berry. Athletes use it before, during, and after workouts for electrolytes without the calories of Gatorade.

Nuun is good for your health (low calorie, low carb, low sugar, no artificial flavors or colors), and good for the planet - one tube prevents the need for ten 16-oz plastic bottles from single-use sport drinks. Last year, Nuun saved over 100 million single use plastic bottles from adding to plastic landfill masses!

And while Nuun is known more for their tablets, we find the powder packets to be the superior form when it comes to mid-workout hydration.

Many say the tablets make water taste better and encourage them to drink more, but taste is subjective—some compare it to Alka-Seltzer or say it’s tasteless. The effervescent fizz is a plus for some and a drawback for others.

I researched and sampled the Nuun tablets, and while I think they may be a viable option for some people, I'll continue to recommend Live it Up Vital Minerals for hydration support. Follow along to find out why.

While the tablet does take a bit longer to dissolve (almost a full 5 minutes after I dropped it in), the flavor and saltiness are mild with a hint of citrus.
