Q. I have been seeing lots of advertisements for electrolyte drinks and powders lately and I have been tempted to try them. Are they really better for you than drinking plain water?

A. It feels like you can’t turn on the TV or walk into a store without seeing a new drink promising more energy or better hydration. It’s smart to stop and consider whether they’re actually helpful. Our AgeSpan dietitians hear this question often when they’re out in the community.

AgeSpan Dietitian Leigh Hartwell says it’s always a good idea to start with water. Dehydration is a common reason older adults end up in the hospital.

As we age, reduced kidney function and other changes can make it more difficult to retain fluids and we’re less likely to feel thirsty. Most adults should aim for 48 and 64 ounces of water each day.

Electrolytes can help the body maintain a balance of fluids, but it’s best to get them from food. Good sources include bananas, avocados, salted nuts, yogurt, cheese, and whole grains. If you can’t get enough through food or have trouble staying hydrated, an electrolyte supplement might help, but check with your doctor first.

If you’re shopping for electrolyte drinks, be sure to check the ingredient list carefully. A few things to watch out for include:

Sodium – Many electrolyte drinks are high in sodium, which can be risky for people with hypertension.

Potassium – People with high blood potassium and kidney disease may need to avoid extra potassium.

Sugar – Sports drinks can be high in sugar, which can be problematic for older adults with diabetes. Sugar substitutes can also have side effects.

As always, it’s best to talk with your doctor before starting any supplement. They can help you choose the safest way to stay hydrated and healthy throughout the holiday season and beyond.
