What Do Electrolytes Do?
Last updated: November 2025
Introduction: Why Electrolytes Matter
Whether you’re heading to the gym, loading your gym bag for a training day, or working with a personal trainer, hydration plays a bigger role in your performance than most people realise. Electrolytes—essential minerals like sodium, magnesium, potassium, and calcium—help keep your body functioning properly during exercise, improving everything from energy levels to post-workout recovery.
This guide explains what electrolytes are, what electrolytes do, what drinks have electrolytes, the benefits of electrolytes, natural sources of electrolytes, and when to take them for optimal performance. It also introduces how purified, mineral-balanced water—like the water from the Bluewater Flow Station™ —supports better training, faster recovery, and sustainable refilling for studios, gyms, and wellness spaces.

1. What Are Electrolytes?
Electrolytes are minerals that carry an electrical charge. They exist in your blood, sweat, and cells, and help regulate crucial functions such as:
- Fluid balance
- Nerve signalling
- Muscle contraction
- pH regulation
- Energy production
If you’ve ever wondered “what are electrolytes?” or “what are electrolytes good for?”, the answer is simple: they keep your body performing at its best, especially when exercising.
Why Do We Lose Electrolytes?
When you sweat—during running, cycling, weight training, or any intensive workout—you lose both water and electrolytes, especially sodium. Replacing both is essential to avoid:
- Fatigue
- Muscle cramps
- Headaches
- Dizziness
- Poor performance
This is why electrolyte drinks, electrolytes water, and natural electrolytes have become staples in fitness routines across the UK.

2. What Do Electrolytes Do?
People search this question constantly: What do electrolytes do? Do electrolytes give you energy? Are electrolytes good for you?
Here’s what science says:
1. Support Muscle Function
Electrolytes—especially potassium, calcium, and magnesium—enable proper muscle contraction.
Low electrolytes increase the risk of:
- Cramps
- Twitching
- Weakness
- Slower recovery
2. Improve Hydration Efficiency
Electrolytes help your body absorb and retain water more effectively than plain water alone.
This is why water with electrolytes or electrolytes drinks are popular among athletes.
3. Maintain Nervous System Balance
Your nerves require electrical signals to function. Electrolytes maintain these signals, impacting:
- Coordination
- Reaction speed
- Focus during training
4. Aid Post-Workout Recovery
Electrolytes are crucial in post workout muscle recovery, especially after long or intense sessions.
Combined with hydration, they support:
- Faster glycogen restoration
- Better energy output the next day
- Reduced soreness
- Improved endurance
If you've ever shopped for a post-workout recovery drink, the best options always contain electrolytes.

3. Drinks With Electrolytes: What to Choose
Searches for “what drinks have electrolytes?” or “how to get electrolytes” are extremely common in the UK. Here’s what to know.
1. Natural Sources of Electrolytes
These foods and drinks are considered natural electrolytes:
- Coconut water
- Mineral water
- Bananas (potassium)
- Leafy greens (magnesium)
- Milk (calcium + potassium)
- Citrus fruits
- Avocado
- Salt
2. Electrolyte Drinks & Water With Electrolytes
These include:
- Electrolytes water
- Electrolytes drinks
- Natural electrolytes drink
- Drinks with electrolytes (commercial sports drinks)
- Best natural electrolytes options (low sugar, mineral-balanced)
3. Are Electrolytes Good for You?
Yes—when consumed appropriately.
They are essential for hydration, performance, and recovery, making them valuable during:
- Strength training
- Hot yoga
- Cycling
- Running
- HIIT
- Football
- Long gym sessions
4. When to Take Electrolytes
Timing matters. These are the most searched questions:
1. Daily Electrolytes – Should You Take Them?
You can include daily electrolytes if you:
- Train regularly
- Sweat heavily
- Drink coffee (a mild diuretic)
- Work physically demanding jobs
2. Before Training
Taking electrolytes before a training day improves:
- Energy
- Endurance
- Hydration efficiency
3. During Training
Great for long or intense sessions—common with runners, cyclists, and lifters.
4. Post-Workout Recovery
The best time to take electrolytes is within 30–60 minutes post-workout.
This supports:
- Glycogen restoration
- Reduced soreness
- Muscle repair
- Faster recovery
If you're looking for the best post-workout recovery drink or the best natural electrolytes, choose options with balanced minerals and no added sugar.
5. Mineral Water Benefits & Natural Sources of Electrolytes
Many people search for mineral water benefits, natural source of electrolytes, and best natural electrolytes.
Why Mineral Water Helps
Mineral water contains naturally occurring electrolytes such as:
- Magnesium
- Calcium
- Potassium
- Bicarbonates
Benefits include:
- Better hydration
- Muscle function support
- Improved electrolyte balance
- Great taste without additives
This makes mineral-balanced water ideal for people searching for electrolytes natural or natural electrolytes drink options.
6. Why Hydration Matters for Athletes
A common UK search phrase: “why is hydration important for athletes?”
Hydration Affects:
- Strength
- Endurance
- Focus
- Heat tolerance
- Muscle recovery
Dehydration as low as 2% body weight can significantly reduce performance.
This is why athletes, PTs, and serious gym-goers prioritise:
- Electrolytes water
- Water with electrolytes
- Electrolytes drinks
- Natural electrolytes sources
