About Electrolytes

Electrolytes are essential minerals that carry an electrical charge when dissolved in fluids within the body. They play a crucial role in maintaining fluid balance, supporting muscle contractions, enabling nerve communication and helping regulate various bodily functions.
Key electrolytes include sodium, potassium, magnesium, calcium, chloride, phosphate and bicarbonate. Together, they help your body absorb and retain fluids effectively while supporting normal muscle and nerve function.

While many electrolytes are obtained through a balanced diet, there are times when additional support may be beneficial. Intense exercise, hot weather, travel, illness, or prolonged sweating can increase electrolyte losses, making supplementation a convenient way to help maintain hydration and well-being.

What NOA Thinks About Electrolytes

Megan Hallett, Head of Nutrition at NOA, says:
"Electrolytes aren't currently markers on our blood test, but how you're feeling around hydration, energy and muscle function can be affected by several other things too, including thyroid function and iron status. If electrolytes alone aren't making the difference you expected, a NOA blood test can help rule other causes in or out."

Electrolytes | What Do They Do In Your Body?

Sodium: Sodium helps regulate fluid balance inside and outside of cells. It supports hydration, helps maintain blood volume and plays an important role in nerve signalling and muscle function.

Chloride: Often paired with sodium, chloride helps maintain fluid balance and supports healthy digestion through the production of stomach acid.

Potassium: Potassium works alongside sodium to regulate fluid levels and supports normal muscle contractions, including those of the heart.

Magnesium: Magnesium contributes to normal muscle function, supports energy-yielding metabolism and helps reduce feelings of tiredness and fatigue. Magnesium is a popular addition to many wellness routines.

Calcium: Well known for supporting bone health, calcium also contributes to normal muscle function and nerve transmission.

Phosphate: Phosphate plays a role in energy production, cellular repair and maintaining healthy bones and teeth.

Bicarbonate: Bicarbonate helps maintain the body's acid-base balance, supporting normal pH levels within the bloodstream.

What Are the Benefits of Electrolytes?

Fluid Balance & Hydration: One of the most recognised electrolyte benefits is their role in maintaining hydration. Electrolytes help your body absorb and retain water more effectively.

Muscle Function: Electrolytes help muscles contract and relax normally. This makes them particularly important during and after exercise, especially as you may have lost electrolytes through sweat.

Nerve Health: The nervous system relies on electrolytes to transmit signals throughout your body, supporting normal communication between your brain, nerves and muscles.

Blood Pressure & pH Balance: Electrolytes can help to regulate your blood pressure and pH balance, both of which are important to feel your best.

Everyday Energy & Wellbeing: When hydration and electrolyte levels are supported, many people find it easier to stay focused throughout the day, particularly during periods of increased physical activity or hot weather.

Electrolytes vs Regular Water

Water remains the foundation of good hydration; however, there are several situations when water alone may not be enough and where electrolyte drinks can offer additional support.

You may benefit from electrolyte supplementation when:

  • Exercising for longer than 60 minutes
  • Participating in high-intensity workouts
  • If you've been spending long periods in hot weather
  • If you're travelling to warmer climates than you're used to
  • If you're recovering from sickness

Electrolyte drinks replace both fluids and essential minerals, helping support hydration when water alone may not fully replenish what has been lost.

Finding the Best Electrolytes for Your Lifestyle

The best electrolytes for you will depend on your goals, activity levels and personal preferences.

If you're looking for daily hydration support, low-sugar electrolyte powders may be ideal. For athletes and fitness enthusiasts, higher-performance formulas containing sodium, potassium and magnesium may be more suitable.

Popular options within our collection include Humantra Electrolytes and Puresport Electrolytes, both designed to provide convenient hydration support while fitting seamlessly into active lifestyles.

Frequently Asked Questions

WHAT EXACTLY ARE ELECTROLYTES?

Electrolytes are minerals such as sodium, potassium, calcium and magnesium that carry an electrical charge within the body. They help regulate hydration, muscle function, nerve signalling and fluid balance.

DO I NEED ELECTROLYTE SUPPLEMENTS?

While electrolytes can be obtained through food and drink, many people find supplements useful during periods of increased fluid loss, such as exercise, hot weather, travel or illness.

WHAT FOODS CONTAIN ELECTROLYTES?

Bananas, potatoes, spinach, dairy products, nuts, seeds, legumes and coconut water all naturally contain electrolytes.

HOW MUCH SHOULD I TAKE AND WHEN?

Always follow the instructions provided on your chosen supplement. Electrolyte products are commonly used before, during or after exercise, or during periods of increased hydration needs.

ARE THERE ANY SIDE EFFECTS?

When taken as directed, electrolyte supplements generally come without side effects. If you do have a medical condition or take prescriptions, consult a healthcare professional before use.

CAN PREGNANT OR BREASTFEEDING WOMEN USE ELECTROLYTES?

Electrolyte drinks may help support hydration during pregnancy and breastfeeding. However, it's always advisable to speak with your healthcare provider before introducing new supplements.

WHAT'S THE DIFFERENCE BETWEEN ELECTROLYTE POWDERS, TABLETS AND CAPSULES?

Powders and effervescent tablets dissolve in water, providing hydration and electrolytes together. Capsules offer a convenient option when you're on the go and prefer not to carry a drink mix.

DO I NEED ELECTROLYTES AFTER EVERY WORKOUT?

Not always: for shorter or lower-intensity workouts, water is often sufficient. Electrolytes may become more beneficial during longer sessions, high-intensity training, or exercise performed in hot conditions.

HOW CAN I STAY HYDRATED DURING SUMMER WORKOUTS?

Start hydrating before exercise, drink consistently throughout your session, and consider an electrolyte supplement. Always wear breathable clothing, and avoiding peak heat can also help support hydration.
