If you feel like it’s become commonplace for your kid to bring a water bottle with them everywhere they go, you are probably not alone! It seems as though hydration is top of mind for many parents -- and for good reason! Being adequately hydrated keeps kids’ bodies healthy as well as helps fight brain fog and fatigue. 

And when it comes to staying properly hydrated, many kiddos are fine to drink plain water throughout the day. However, in some situations, you may want to reach for an electrolyte drink for your kiddo. Electrolytes help maintain the proper balance of liquid in the body and can be helpful during illness (especially with diarrhea or vomiting), during intense physical activity or hot weather. 

Parents should choose electrolyte drinks carefully, though, as they are not all created equal. Keep reading to find out what makes an electrolyte drink a good choice for kids. 

Modest amounts of electrolytes

Many electrolyte drinks are formulated for adults and contain more electrolytes than kids need. Consuming too many electrolytes can also alter hydration status so it’s best to check the nutrition label before purchasing. Aim to keep the daily value (found on the nutrition label) of nutrients like sodium, potassium and magnesium to less than 20%. Better yet? Seek out a formulation especially made for kids. 

Watch for out for added sugars

A small amount (1 or 2 grams) of added sugar helps the body properly absorb electrolytes and is not a cause for concern. However, it’s likely best to steer clear of drinks with large amounts of added sugar. In most cases, kids do not need the extra energy it provides on a day-to-day basis. During times of prolonged intense physical activity, an electrolyte drink with added sugar may help replenish energy stores. 

Check the ingredient label

Sometimes electrolyte drinks contain additional ingredients that may not be suitable for kids, so always thoroughly check the ingredient label. One example is caffeine which according to the American Academy of Pediatrics should be avoided for all kids. Other supplemental ingredients, natural or not, may not be suitable for kids as well.

Summary

When choosing an electrolyte drink for kids be sure to check the nutrition label. Ensure the quantities of electrolytes are appropriate, the added sugars are low and that there aren't any potentially negative ingredients such as caffeine. If possible, seek out an electrolyte drink formulated specifically for kids.
