8 drinks that replenish electrolytes, support hydration

Electrolyte drinks can help replace minerals lost through sweat, illness or prolonged exercise. While plain water is enough for most daily hydration needs, drinks containing sodium, potassium and other electrolytes may support recovery after intense workouts, heat exposure or diarrhoea.

When do you need electrolyte drinks?

Most healthy adults can stay hydrated with water throughout the day. Electrolyte drinks become more useful after vigorous exercise lasting more than an hour, excessive sweating, vomiting, diarrhoea or extended time in hot weather.

1. Electrolyte-infused water

Electrolyte-infused water contains added minerals such as sodium, potassium and magnesium, with some varieties also including natural fruit flavourings.

These drinks are generally low in sugar, making them a suitable option for people looking to replace electrolytes without consuming the higher carbohydrate content found in sports drinks. However, some flavoured varieties may contain added sugars, so it's worth checking the label.

2. Coconut water

Coconut water naturally contains potassium, along with smaller amounts of sodium and other electrolytes.

It has long been used as a natural rehydration option and also provides antioxidants that may help protect cells from exercise-related stress. Compared with many sports drinks, coconut water is typically lower in added sugar.

3. Sports drinks

Sports drinks are designed for endurance athletes and people performing prolonged, high-intensity exercise.

They contain carbohydrates for energy alongside electrolytes that help replace minerals lost through sweat. For people with lower activity levels, however, their higher sugar content may offer little benefit beyond extra calories.

4. Pedialyte

Pedialyte is an oral rehydration solution formulated with water, electrolytes, zinc and carbohydrates.

It is commonly used to replace fluids lost through dehydration and contains fewer carbohydrates than many sports drinks, making it more suitable for hydration than fuelling prolonged exercise.

5. Cow's milk

Milk naturally provides electrolytes such as sodium and calcium, along with protein and carbohydrates.

Research suggests it can be an effective recovery drink after exercise by helping restore fluids while also supporting muscle repair thanks to its protein content.

6. Pickle juice

Pickle juice contains sodium, potassium and other minerals that may help replace electrolytes after heavy sweating.

Some athletes also use it to help relieve muscle cramps. However, because it is very high in sodium, it may not be suitable for people with high blood pressure or those following a low-sodium diet.

7. Maple water

Maple water, made from maple tree sap, contains potassium, calcium and naturally occurring antioxidants.

Although it may support post-workout recovery, it contains very little sodium, meaning it may not replenish electrolytes as effectively as other options after intense sweating.

8. Low-fat chocolate milk

Low-fat chocolate milk combines carbohydrates, protein and electrolytes, making it a practical post-workout recovery drink.

It also supplies calcium and vitamins that support muscle function and recovery, while providing fluids to help restore hydration.

What to look for in an electrolyte drink

Not all electrolyte drinks are formulated the same. Consider these factors before choosing one:

• Electrolytes: Look for adequate sodium and potassium, especially after heavy sweating.
• Sugar content: Higher-carbohydrate drinks are best reserved for prolonged, intense exercise.
• Ingredients: Choose drinks made with simple, natural ingredients and limit artificial additives where possible.
• Purpose: Match the drink to your needs, whether it's everyday hydration, exercise recovery or treating dehydration.

The bottom line

Water remains the best choice for everyday hydration. However, electrolyte drinks such as coconut water, electrolyte-infused water, Pedialyte, milk and sports drinks can help replenish minerals and fluids after intense exercise, illness or excessive sweating. Choosing the right option depends on your activity level, health needs and the amount of electrolytes you need to replace.
