Nuun vs. Liquid IV: Are These Popular Electrolyte Brands Really Worth It?
Quick Verdict
When it comes to hydration, Nuun and Liquid IV both fall short of delivering a truly effective electrolyte solution. If you're serious about rehydration and energy recovery, Cure Hydration Electrolytes are a better alternative. Its science-backed formulation and clean ingredients make it a more reliable choice for those looking to stay hydrated without unnecessary additives.
With hydration becoming a focal point for fitness and daily wellness routines, electrolyte supplements like Nuun and Liquid IV have gained popularity.
They claim to enhance hydration, boost energy, and support recovery. However, after testing both, I found several reasons why neither lives up to the hype. Here's a detailed breakdown of each to help you decide if they’re really worth your time and money.
Nuun Hydration
Nuun positions itself as a low-sugar, electrolyte-rich hydration tablet meant to dissolve in water. Its claims focus on providing essential electrolytes without added sugar.
Pros:
- Low Sugar Content: Each tablet has only 1g of sugar, which may appeal to those wanting to limit sugar intake.
- Portable Tablets: Convenient to carry around and easy to dissolve in water, making it ideal for on-the-go hydration.
Cons:
- Bloating & Gastrointestinal Issues: Some users report bloating and stomach discomfort, possibly due to added ingredients like stevia and sorbitol.
- Artificial Sweetener Taste: The stevia used to sweeten Nuun has a distinct aftertaste that can be unpleasant for many, overshadowing the flavor.
- Limited Hydration Support: With lower sodium content than competitors, Nuun may not effectively support serious hydration or recovery after intense exercise.
Key Ingredients in Nuun
- Electrolytes (Sodium, Potassium, Magnesium, Calcium): Essential but offered in smaller amounts than some competitors.
- Stevia & Sorbitol: These sweeteners provide a low-sugar option but may cause digestive discomfort.
- Vitamin C & B Vitamins: Included to support energy levels, but doses are minimal.
Why It Falls Short: While the low-sugar approach is commendable, Nuun’s limited sodium levels mean it may not be potent enough to support hydration for athletes or those with intense daily routines. Additionally, the stevia aftertaste and potential digestive side effects make it less appealing.
Liquid IV
Liquid IV markets itself as a hydration multiplier using Cellular Transport Technology (CTT®) to enhance water absorption. It claims to deliver the hydration equivalent of drinking 2-3 bottles of water.
Pros:
- High Sodium Content: With 500mg of sodium, it aims to support rapid rehydration, especially after physical exertion.
- Easy to Mix Powder: The powder mixes quickly in water and is portable, making it convenient to use.
Cons:
- High Sugar Content: Each stick contains 11g of sugar, which can be excessive if consumed regularly or in larger quantities.
- Overly Sweet Flavor: The taste is quite sweet, which may not appeal to everyone, especially those sensitive to sugar or artificial flavors.
- Potential for Sugar Crashes: The high sugar content can lead to energy spikes and crashes, making it less ideal for sustained hydration.
Key Ingredients in Liquid IV
- Electrolytes (Sodium, Potassium): Higher levels of sodium for rehydration, but limited potassium compared to similar products.
- Dextrose & Cane Sugar: High sugar levels, intended to enhance absorption but may lead to sugar crashes.
- B Vitamins & Vitamin C: Added to boost energy, though amounts are small relative to daily needs.
Why It Falls Short: While Liquid IV’s high sodium content is useful for quick hydration, the excessive sugar is a major drawback. Regular use can add unnecessary sugar to your diet, potentially affecting energy stability and overall health.

Final Thoughts
While both Nuun and Liquid IV offer certain benefits, they come with notable downsides that may not make them the best options for long-term hydration needs. The aftertaste and low sodium in Nuun limit its effectiveness, while Liquid IV’s high sugar content detracts from its benefits. For a more balanced option, Cure Hydration Electrolytes provide the necessary electrolytes and hydration support without unwanted additives.
