What customers say
Customers generally appreciate the Nuun Sport Electrolyte Drink Tablets for their effectiveness in replenishing electrolytes and aiding hydration, especially after workouts or during hot weather. The packaging is praised for its convenience and portability, making it easy to carry in sports bags. Many users enjoy the taste, with some comparing it to grape soda, although a few found the grape flavor medicinal. The product is noted for its good balance of electrolytes and magnesium, though some feel it lacks sufficient sodium, magnesium, and potassium compared to other brands. The tablets dissolve quickly in water and are sugar-free, which many customers prefer. Overall, the product is seen as high-quality and beneficial for maintaining hydration during physical activities.

Hydration and good flavours!
Verified purchase
These effervescent tablets dissolve fairly quickly and easily in water, and unlike some other hydration tablets are fairly flavourful, but not overpowering. Low carb and calories too! The grape flavour is pretty tasty.

Great hydration electrolytes! Good quality ingredients, good taste, not too sweet. Easy to use, just drop it in the water bottle and shake. I use it at the gym.

Excellent Hydration and Taste
Verified purchase
Great product for hydration during workouts and hot days. The quality and ingredients are top-notch for no artificial aftertaste, and the grape flavor is refreshing without being too sweet. It dissolves quickly, helps maintain electrolytes, and noticeably improves recovery. The size is convenient for travel or gym bags. A reliable, effective hydration solution for active people.

I have only tried this one and noticed a major difference as it really did help with the soreness and dehydration after the work out. the raspberry lemonade tasted better though in my opinion.

Recommended for people with POTS

Honestly it’s great. Tried both grape and strawberry lemonade and I enjoyed them both. The taste is a bit to get used to but that’s most electrolytes, especially since it’s practically no sugar. I find the quality to be good, it mixes into water pretty quick and it helps me a lot with my hydration.
