Choosing an electrolyte drink: what to look for for sport and everyday use

An electrolyte drink may seem simple at first glance: water with minerals, flavouring and sometimes vitamins. However, products can vary considerably in their levels of sodium, sugar, calories and carbohydrates, as well as serving size and ease of use. If you only look for terms such as “hydration”, “isotonic” or “sports formula”, you may end up buying a product that does not suit your training goals.

For adults in the Netherlands, these are the three main pitfalls to be aware of:

• A sports drink is not automatically sugar-free. An isotonic sports drink may contain carbohydrates. This can be useful during prolonged exercise, but less suitable if your main aim is to limit calories.
• The amount of electrolytes means little without considering serving size. Always compare the amount of sodium, potassium and magnesium per can, stick or prepared serving.
• Vitamins and additional ingredients can distract from what matters most. Caffeine, amino acids, taurine or herbs do not automatically make a product suitable for hydration during exercise. Look first at fluids, sodium and when you intend to use it.

Which electrolytes are important?

Electrolytes are minerals that carry an electrical charge when dissolved. Sports drinks mainly contain sodium, potassium, magnesium, calcium and chloride. When you sweat, you lose fluids and salts, but the amount varies from person to person and depends on the temperature, duration and intensity of the exercise.

1. Check the sodium per serving

For many sportspeople, sodium is a useful point of comparison. A drink containing 500 mg of sodium per 330 ml has a different composition from a powder that provides 279 mg of sodium after being mixed with 500 ml of water. So do not just look for “lots of electrolytes” on the front of the pack; check the nutrition table.

A sports drink with electrolytes may be suitable around intense training sessions or competitions. For a short, gentle session, plain water may be enough. There is no fixed amount that is right for every sportsperson.

2. Look at sugar and carbohydrates

A sugar-free electrolyte drink with few calories is suitable for consumers who do not want to drink extra energy. For example, Applied Nutrition NA11 lists 0 grams of sugar and 7 kcal per 330 ml can. According to the product information, the can contains 500 mg of sodium, 190 mg of potassium and 56 mg of magnesium.

A carbohydrate-rich drink serves a different purpose. Body & Fit Isotronic Drink Tropical contains 29 grams of carbohydrates per 35-gram serving, including 18 grams of sugar, and provides 119 kcal. According to the product information, the powder is intended to be mixed with approximately 500 ml of water. This can be practical during longer endurance sessions when you need carbohydrates as well as fluids.

3. Pay attention to dosage, format and ingredients

A powder or electrolyte stick is lightweight to carry and can be mixed with water to suit your taste. A ready-to-drink can is quicker, but takes up more space and requires no preparation. When choosing an electrolyte supplement, always check:

• the recommended maximum dosage;
• the amount of water per serving;
• sweeteners and caffeine;
• allergens and possible traces;
• warnings for children, pregnancy and medication use;
• the best-before date and storage instructions.

“Contains magnesium and potassium” does not necessarily mean that the amounts are high. According to the product table, Applied Nutrition NA11 contains 56 mg of magnesium and 190 mg of potassium per can. An Applied Nutrition stick lists 133 mg of magnesium and 403 mg of potassium per serving, but also contains added vitamins and other ingredients.

Choose according to when you will use it

An electrolyte drink for sport should match the activity:

• Weight training or team sports: choose a compact drink or stick that is easy to use during or around your training session.
• Long bike rides, running races or endurance training: a powder with carbohydrates can provide energy as well as fluids and electrolytes.
• Travel, commuting or everyday use: a sugar-free drink or small shot is practical if you want to limit calories and preparation.
• Before or after exercise: pay particular attention to caffeine. A caffeinated product is not automatically suitable for every time of day or every user.

Frequently asked questions about electrolyte drinks

Is an electrolyte drink needed for every training session?

No. For short or gentle training sessions, water is often sufficient. An electrolyte drink for sport may be more relevant during prolonged or intense exercise, in warm weather or when you sweat heavily. Consider your activity and the nutritional values per serving.

What is the difference between electrolyte powder and a ready-to-drink can?

With electrolyte powder, you can adjust the amount of water and often make several servings cost-effectively. A can is ready to use straight away, but contains a fixed amount and is heavier to carry. Electrolyte sticks combine a fixed dosage with portability.

How long does an electrolyte drink remain usable?

Unopened products remain usable until the date shown on the packaging, provided they are stored according to the label. Seal powder securely after opening and store it in a cool, dry and dark place. According to the product instructions, an opened can or bottle should be refrigerated and used within the stated period. If you have allergies, take medication or are pregnant, always check the current label and consult a doctor or pharmacist if in doubt.
