Best Electrolyte Drinks

Verywell / Sabrina Jiang

Electrolyte-enhanced beverages, or sports drinks, help replenish water, electrolytes, and energy lost during exercise. These drinks often contain potassium, sodium, magnesium, and calcium, which help combat dehydration, prevent muscle cramping, and delay fatigue.

The human body has mechanisms to maintain adequate fluid and electrolyte balance, so for most healthy individuals, eating a balanced diet and consuming adequate water intake is sufficient. Registered Dietitian, Merrill Brady, MS, RDN, CDN notes, "Clients often ask if they should be drinking an electrolyte-enhanced beverage during or after their workouts. While my advice depends on the individual and the exact nature of their workout, I generally recommend sticking to regular water, unless they are heavily sweating and/or intensely working out for over an hour."

While traditional manufactured and artificially flavored sports drinks have long been the drink of choice in the sports and fitness world, recent research suggests that coconut water may be just as effective at promoting rehydration with less incidence of stomach upset and bloating. Electrolyte drinks have expanded beyond the world of athletics to meet the needs of anyone who may benefit from a hydration and mineral boost.

What to Look for in Electrolyte Supplements


Check the label to see what electrolytes are included in the electrolyte drink. Whether you're looking for a slight pick-me-up in your regular water, a way to rehydrate when you're sick, or an electrolyte-packed sports drink to fuel your activity, there are lots of different options. Electrolytes to look for include sodium, magnesium, calcium, phosphorus, and chloride.


Electrolyte drinks can come in premixed liquid form or powder form. There are also naturally occurring electrolyte drinks such as coconut water available. Consider how and when you will be using the beverage; for example, it may be more convenient to carry a powdered electrolyte packet while traveling, whereas a ready-to-drink option may be better for immediate use.

Other Additives

Some electrolyte drinks come with extra nutrients or ingredients. While it is generally best to steer clear of beverages high in sugar or those containing artificial ingredients, some beverages contain extra ingredients like caffeine or vitamin C that may be beneficial.

Electrolyte Drink Dosage

Always speak with a healthcare professional before adding a supplement to your routine to ensure that the supplement is appropriate for your individual needs and which dosage to take.

There is no established RDA (Recommended Daily Allowance) for electrolyte drinks. However, there are established recommendations for the minerals that they contain. These recommendations differ based on age, gender and overall health status. It is important to note that if you are pregnant or lactating, there are specific recommendations for each mineral.

Here are the recommendations, established by the Food and Nutrition Board of the Institute of Medicine (NASEM), for the six electrolyte, essential minerals for men and women between the ages of 19-50 years of age:

  • Sodium: Sodium does not have an RDA, but the 2020-2025 Dietary Guidelines for Americans recommends <2,300 milligrams/day for adults.
  • Potassium: Adequate Intake (AI) per day is 3,400 milligrams for men and 2,600 milligrams for women
  • Calcium: RDA is 1,000 milligrams for men and women
  • Chloride: Adequate Intake (AI) per day is 2.0 grams
  • Phosphorus: RDA is 700 milligrams
  • Magnesium: RDAs are as follows:
  • 19-30 years: 400 milligrams men, 310 milligrams for women
  • 31+ years: 420 milligrams for men, 320 milligrams for women

Frequently Asked Questions

  • Can you drink too many electrolytes?

    In general, it’s unlikely to take in too many electrolytes from electrolyte drinks, unless you’re drinking several servings in one day. If you are consuming several electrolyte drinks daily, you may want to be wary of your electrolyte intake when combined with the electrolytes you get from food, especially sodium. 

    Too much sodium is linked to high blood pressure and heart disease. The 2020-2025 Dietary Guidelines advise consuming no more than 2,300 milligrams of sodium per day. For reference, one 12-ounce serving of coconut water has 55 milligrams of sodium, one Nuun tablet provides 300 milligrams, and one 12-ounce serving of Pedialyte has 370 milligrams.

    If you’re already eating foods high in sodium, it can start to add up when adding electrolyte drinks into the mix

  • How can I make my own electrolyte drink?

    Most electrolyte drinks on the market contain sodium, potassium, calcium, and magnesium—all of which can be found in food. Try this DIY electrolyte drink. Mix 2 cups water, 1 1/2 cups coconut water, 1/4 cup pomegranate juice, 1/4 cup lemon juice, and 1/4 teaspoon salt.

    This recipe makes four 1 cup servings, each of which provides 250 milligrams of sodium, 258 milligrams potassium, and 90 milligrams of calcium.

Best for Keto: Nuun Sport Electrolyte Drink Tablets

Nuun sport electrolyte drink tablets
  • Good for travel

  • Flavor variety

  • Contains additives

People on the ketogenic diet typically have higher electrolyte needs and are more prone to dehydration, especially when beginning the diet. When the body is first adapting to the ketogenic diet, people experience fluid losses, which lead to less bloat and a reduction in water weight; however, the loss of fluid also leads to electrolyte depletion. The dreaded “keto flu,” or symptoms of fatigue, headache, and irritability, can arise from these electrolyte imbalances. 

Sport is keto-friendly! These electrolyte tablets contain only one gram of sugar, 15 calories, and no artificial sweeteners or flavoring. They are sweetened using high-quality stevia, which will not disrupt the sensitive ketogenic cycle like regular sugar and carbohydrates.

The convenient tablets mix easily with water to create a hydrating, tasty beverage that comes in a variety of flavors, including Lemon Lime, Tri-Berry, Citrus Fruit, and Orange. Each tube provides 10 tablets that contain a balance of five essential minerals. They’re also soy-free, gluten-free, kosher, and vegan.

Electrolytes included: sodium, potassium, chloride, magnesium, calcium | Servings per container: 10 tablets per tube | Calories per serving: 15 | Sugar per serving: 1 grams | Vegan: Yes | Gluten-free: Yes | Non-GMO: Yes | Organic: No | Additives: Dextrose, stevia, malic acid

Best for People with Diabetes: Ultima Replenisher Ultima Replenisher Electrolyte Hydration Powder, Variety Pack, 20 Count Stickpacks

Ultima Replenisher Ultima Replenisher Electrolyte Hydration Powder
  • Contains all six electrolytes

  • Good for travel

  • Contains vitamin C

  • Expensive

Ultima Replenisher Electrolyte Powder is a great choice for a sugar-free beverage that will replenish electrolyte levels, hydrate effectively, and provide supporting minerals without affecting blood sugar levels. Sweetened with stevia, Ultima is a delicious, zero-carb drink that is perfect for people with diabetes. 

Most electrolyte drinks contain sugar and carbohydrates, which can cause blood sugar modulations in people with diabetes. Ultima Replenisher Electrolyte Powder is a great product for people with diabetes to rehydrate without any effect on blood sugar. People with diabetes have a higher risk of dehydration, as high blood glucose levels cause the kidneys to work harder to remove excess glucose from the blood and excrete urine. While this is effective for reducing blood sugar levels, it can lead to fluid and electrolyte loss.

The Ultima Single Serve Variety Pack comes with 20 sticks in a variety of flavors, including cherry pomegranate, grape, lemonade, orange, and raspberry. The formulation also contains vitamin C, which can help to boost immunity.

Electrolytes included: magnesium, potassium, sodium, chloride, calcium, phosphorus | Servings per container: 30 | Calories per serving: 0 | Sugar per serving: 0 grams | Vegan: Yes | Gluten-free: Yes | Non-GMO: Yes | Organic: No | Additives: Stevia, malic acid

Best Electrolyte Water: Essentia Water LLC Ionized Alkaline Bottled Water

Essentia Water LLC Ionized Alkaline Bottled Water
  • No mixing needed

  • Crisp taste

  • Contains only trace amounts of electrolytes

  • Plastic waste

Essentia Water is ionized alkaline water that tastes great and has small amounts of beneficial electrolytes. Essentia uses a proprietary ionization process to purify, add small amounts of electrolytes, and remove bitter-tasting ions. This three-step process first purifies the water, removing unwanted particles through microfiltration and reverse osmosis. The water is then infused with trace amounts of electrolytes. Finally, bitter-tasting acidic ions are removed. The result is alkaline water with a pH level of 9.5 or higher.

Alkaline water is less acidic than regular water and is rich in alkalizing compounds that may improve hydration status. Essentia contains minimal amounts of minerals, so it will not provide essential electrolytes for highly active athletes, but it is a fantastic, great-tasting way for anyone to rehydrate.

Electrolytes included: magnesium, potassium, sodium, chloride, calcium, phosphorus | Servings per container: 1 liter bottle | Calories per serving: 0 | Sugar per serving: 0 grams | Vegan: Yes | Gluten-free: Yes | Non-GMO: Yes | Organic: No | Additives: No
