Who Should Buy Electrolyte Tablets and Supplements

Athletes who exercise at moderate to high intensity for an hour or more may benefit from using electrolyte tablets and supplements. 3 Do electrolytes improve athletic performance? Not directly. More research is needed to determine if micronutrient and trace mineral supplementation have an effect on athletic performance. 4

What’s important for athletic performance is making sure you stay hydrated, and electrolytes help regulate the fluid in your body so you function optimally. 5

As for the rest of us who exercise moderately, we often don’t need additional electrolyte supplements if we eat a healthy diet. However, there may be certain cases where non-athletes would benefit from taking an electrolyte supplement: during illness, dehydration or malnutrition.

In these situations, using an electrolyte tablet or supplement may prevent you from developing symptoms caused by low electrolyte levels. One main function of electrolytes is to push nutrients into your cells and waste out of your cells. 6 So, if you’ve been feeling sluggish, it may indicate that your diet (therefore your electrolyte intake) is subpar. Read more in our post about How to Get More Electrolytes (and When You Need Them).

Important Features to Consider

The most well-rounded electrolyte tablets and supplements contain the same few important features. Here’s what to consider when selecting the best electrolyte tablet or supplement to suit your needs:

  • Electrolyte levels. Many electrolyte tablets and supplements contain sodium, which is also found in our diets in the form of salt, processed foods, canned foods, condiments, fast food, pickled foods and more. 7 A vast majority of Americans consume more than 3400mg sodium per day (the recommendation is 2300mg). 8 So, we all have to pay attention to sodium levels in our diet and any electrolyte supplement we take. If you think you already meet or exceed the recommended daily amount, select a supplement with either low or no sodium, or reduce the amount in your diet to compensate.
  • Format. Electrolyte supplements come in a range of formats, including tablets, powders, capsules, and liquids. Some of these, such as tablets or individually wrapped powders, are more travel-friendly than others. Choose the format which best suits how and when you’ll be wanting to use it.
  • Dietary requirements. If you are vegetarian, vegan, have high blood pressure or diabetes, then make sure you select a supplement which is suitable for your dietary requirements.

Frequently Asked Questions

If you experience any of these symptoms, it’s best to speak to your doctor.
