Are Nuun Tablets Good For Hydration?

Yes, based on key electrolytes, Nuun is good for hydration.

Containing essential minerals makes it a solid formula including calcium, magnesium, chloride, sodium, and potassium. It also checks the boxes to be a healthier option.

Our only main concern is the sugar contents and lack of potency, which we'll discuss further.

Sugar Warning

Many brands such as Nuun claim sugar to be good for hydration, but we don't believe it is. Furthermore, the science shows sugar is very bad for your health.

Only in rare cases of extreme dehydration or malnourishment can sugar show any benefit. Instead, it causes side effects such as energy crashes, fatigue, increased insulin levels, and weight gain.³

Side Effects of Sugar:³

  • Irritability
  • Weight Gain
  • Fatigue
  • Increased Hunger
  • Energy Crash
  • Digestion Problems
  • High Blood Pressure
  • Aging
  • Brain Fog
  • Acne
  • Joint Pain
  • Cavities
  • Sleeping issues

In our Nuun Hydration Tablets review, we believe the risks of sugar outweigh the benefits.

Lack Of Strength

While Nuun Sport is formulated with a basic combo of minerals, it's an electrolyte mix at best. Without any supporting amino acids or antioxidants, it lacks nutritional strength.

You can get a lot done with basic electrolytes, but there's activities you'll need more heavy-lifting ingredients such as at high-altitudes, jet lag, and drinking alcohol. Electrolytes alone won't be powerful or strong enough to see substantial results.

Is it OK To Drink Nuun Everyday?

With each tablet of Nuun you are getting 1 gram of sugar. For this reason, we don't believe it's OK to drink Nuun everyday.

While some will claim 1 gram is not a lot of sugar, taking it consistently everyday is not good and can have negative side effects. Even worse if taking multiple tablets, as many do.

For many modern diets such as keto and paleo, you're supposed to avoid added sugar. You could use products with added sugar occasionally, but avoid doing so on a daily basis.

What Are The Side Effects Of Nuun Hydration?

The main side effects of Nuun hydration would be from sugar.

Those side effects from sugar can include weight gain, fatigue, brain fog, and digestion issues.

Is Nuun better than Gatorade?

Yes, Nuun is better than Gatorade.

Gatorade is loaded with sugar, up to 34 grams per bottle, and also uses sucrose and artificial colors. With only sodium and potassium, Gatorade is a very simplified electrolyte mix.

Nuun has a much lower amount of sugar, 1 gram per tablet, and a more complete electrolyte mix totaling five minerals. Its formula is much healthier, with highlights such as being gmo free.

Nuun Vs Zaca

We reviewed Nuun Tablets in comparison to our Zaca Chewables.

For hydration tablets, we believe Zaca offers a more potent, healthier, and easier-to-use supplement to hydrate.

As a stronger, more powerful supplement — Zaca chewables are made with amino acids, antioxidants, and other key nutrients. As a sugar-free formula, it has none of the side effects that come with sugar consumption. And as a chewable tablet, you can eat Zaca quicker and easier without having to dissolve into water. With these combination of benefits, Zaca is popular among not just fitness enthusiasts but also travel lovers, mountain adventurers, and occasional drinkers.
