You've just powered through a tough workout—now it's time to refuel and rehydrate. 

While water is a go-to choice, if you're pushing yourself hard for an hour or longer—you'll need more than just hydration. Enter electrolyte powder.

These essential salts and minerals carry an electric charge, and as you sweat, your body loses them—and that's where electrolyte drinks come in.

They replenish those vital electrolytes, like sodium, magnesium, potassium, calcium, and chloride, to keep you balanced and thriving.

We've prepared a comprehensive Smart Protein guide to help you understand why taking electrolyte powder post-workout is brilliant for everyone, from seasoned athletes to those taking their first steps towards a healthier lifestyle.

Ready? Let’s dive in.

What are electrolytes?

So, what are electrolytes, exactly? Well, electrolytes—which include specialised minerals like potassium, sodium chloride, calcium, phosphate, and magnesium—can work wonders for your body. 

When combined with transporters like glucose, they can help your cells absorb fluid and keep your body hydrated. Without enough of these magic minerals and fluids, complications, including fatigue, headaches, dizziness, and reduced motor function, can start to creep in.

If you're an athlete or enjoy exercising, you're lucky—electrolytes are essential. During physical exercise, your body loses lots of sodium and chloride. 

These minerals combine to form salt, often seen on your skin post-workout. But don't worry: electrolytes are also essential for those who work outdoors or spend time in hot climates.

Electrolytes replenish your body to keep it functioning at its best—whether you're powering through a workout—basking in the sun, or just going about your day.

Why is it important to rehydrate with electrolytes?

We’ll tell you why. Electrolytes are powerful molecules that work tirelessly behind the scenes to keep your body functioning at its absolute best.

They're involved in countless processes that help everything run smoothly. Let’s look at some of the main powers of electrolytes…

Transmitting nerve signals

First up, electrolytes are like messengers, facilitating the proper communication of electrical impulses between your nerves. 

They make sure that the signals zip back and forth without a hitch, keeping your body in sync and your mind sharp.

Helping blood to clot

Electrolytes also step up in times of need, helping your blood to clot when you have a cut or injury. It's their body-boosting properties that play a vital role in the clotting process, ensuring you can heal and recover effectively.

Aiding muscle contraction

When it comes to your muscles, electrolytes are essential for peak performance. 

They're the secret sauce that ensures your muscles contract and function at their best. Without enough electrolytes, your muscles may start to cramp—which can put a damper on your physical prowess.

These electric chemicals also play a vital role in building and repairing tissues. Yes, they’re the architects of your strength and vitality, helping you stay strong and healthy.

Normalising fluid levels

Let's not forget about their role as the traffic controllers of your body's fluids. Electrolytes work tirelessly to regulate fluid levels, making sure everything flows smoothly and remains balanced.

They keep your hydration on point and your body functioning at its peak.

Maintaining your blood pH levels

Last but not least, electrolytes are the guardians of your blood's pH levels. They ensure that your precious life force stays within a normal range, keeping you in the best possible health.

What are the symptoms of low electrolytes?

If your body has low electrolytes, it can cause a sense of chaos for your performance and recovery. Not ideal.

SmartFact: Roughly 40% of your body weight comes from the fluids inside your cells, while another 20% comes from the fluids outside your cells. 

If you will, picture electrolytes as the maestros of balance, helping your body juggle the levels of fluids inside and outside your cells, maintaining a healthy equilibrium in the process.

Now, it's important to note that it's perfectly normal for electrolyte levels to fluctuate. 

But, sometimes, these levels can become imbalanced—and that's when trouble can arise.

An electrolyte imbalance happens when your body starts producing too many or too few minerals or electrolytes.

There are various factors that can throw your electrolytes off balance…

  • Heavy exercise or physical activity
  • Vomiting and diarrhoea
  • Medications like diuretics, antibiotics, and chemotherapy drugs
  • Alcoholism
  • Cirrhosis
  • Heart failure
  • Kidney disease
  • Diabetes
  • Eating disorders
  • Severe burns
  • Certain forms of cancer

How does replenishing electrolytes boost hydration?

Imagine pushing yourself through a challenging workout, the sweat pouring down your face representing a key sign of your hard work.

Sweat keeps us cool, allowing us to give it our all for longer periods, but here's the deal: when we sweat, we don't just lose water—we lose electrolytes too. 

Electrolytes are minerals, like sodium, magnesium, chloride, and more, that carry an electrical charge, and our bodies desperately need electricity to operate.

Oh, and electrolytes do more than just keep you hydrated—they play a big role in your body. 

Electrolytes help your muscles contract. They support the amazing positive vibes passing through the synapses in your brain—and so much more.

Now, when you think about electrolytes, you may immediately associate them with hydration, thanks to their fame in sports drinks.

See, electrolytes work tirelessly to maintain a healthy balance of water throughout your entire body, even down to a cellular level.

While drinking water is absolutely essential—keeping your electrolyte levels up to par is like giving your body the turbo boost it craves.

The key electrolytes needed for optimum hydration, performance and recovery

Hydration is the foundation of peak performance, and our electrolyte powder has been carefully formulated to provide the essential electrolytes that your body craves.

Sodium plays a crucial role in various aspects of our body's functioning. Here's why it matters for hydration, exercise performance, and recovery…

Hydration: Sodium, in combination with potassium, helps regulate the balance of fluid across cell membranes. This balance ensures that cells have the right amount of hydration to function properly.

The sodium-potassium pump, a cellular mechanism, actively transports sodium out of cells and potassium into cells, maintaining the osmotic balance needed for proper cell hydration.

Exercise Performance: Sodium is essential for the transmission of nerve signals and muscle contractions.

It works alongside potassium to ensure that muscles respond appropriately to nerve signals, supporting optimal muscle function during physical activity.

Balancing sodium and potassium levels is essential for muscular coordination and performance.

Recovery: After exercise, replenishing lost sodium is crucial for restoring electrolyte balance.

Sodium, along with potassium, aids in rehydration and restoring normal cell function. This is vital for recovery after exertion, helping the body recover and prepare for future activities.


Potassium, just like sodium, plays a significant role in maintaining the proper functioning of our body. Let's explore how potassium supports hydration, exercise performance, and recovery…

Hydration: Potassium works hand in hand with sodium to regulate fluid balance within cells, tissues, and organs.

This balance helps prevent dehydration and ensures that cells have the right amount of hydration for optimal function, and by maintaining fluid balance, potassium supports overall hydration in the body.

Exercise Performance: Potassium is essential for muscle contractions and nerve signalling during physical activity

It collaborates with sodium to transmit nerve impulses accurately and trigger muscle contractions.

This teamwork between potassium and sodium is crucial for proper muscle function and optimal exercise performance.

Recovery: After exercising, replenishing electrolytes, including potassium, is vital to restore balance and support recovery.

Potassium—together with sodium—helps in rehydrating the body and restoring normal cell function. Plus, it aids in muscle relaxation, reducing the chances of muscle cramps and promoting a faster recovery after physical exertion.


Calcium has several important roles in the body, including its impact on hydration, exercise performance, and recovery. Let’s dig a little deeper…

Hydration: Calcium plays a role in signalling the kidneys to retain water, which can affect hydration status.

Along with magnesium, calcium helps maintain a proper fluid balance within cells, which is essential for adequate hydration.

Exercise Performance: Calcium is crucial for muscle contraction. When combined with magnesium, the balance between the two minerals is vital.

Magnesium helps in muscle relaxation, enabling a cycle of contraction and relaxation that is necessary for movement during exercise.

Recovery: Calcium supports bone health and can help reduce the risk of stress fractures. It also contributes to muscle relaxation after exercise.

The interplay between calcium and magnesium is important for overall muscle relaxation and recovery after physical activity.


Magnesium is an essential mineral that provides several benefits to the body. It helps maintain normal blood pressure, supports the health of bones and the heart, and is involved in energy production. Here’s a little more on the subject…

Hydration: Magnesium is involved in the regulation of muscle and nerve function, as well as supporting a healthy heart rate.

This can indirectly impact hydration levels by maintaining proper blood volume and overall wellbeing.

Exercise Performance: Magnesium plays a key role in muscle relaxation and contraction. Working in harmony with calcium, magnesium ensures that muscles function optimally during exercise.

While calcium facilitates muscle contraction, magnesium promotes muscle relaxation, allowing for coordinated movements during physical activity.

Recovery: Magnesium assists in muscle relaxation, reducing post-exercise soreness and cramping. It also contributes to energy production, which is crucial for effective recovery after physical exertion.

Adequate magnesium levels can support a faster recovery process.

How to keep your electrolytes in the green and optimise your performance

Electrolyte powder and electrolyte drinks will help you replenish your stores when it counts most. There are other ways of keeping your electrolyte levels in the green, too.

Let’s explore.

Consume Electrolyte Drinks

When we exert ourselves, our bodies crave electrolytes that can be difficult to obtain through regular foods.

Electrolyte-infused drinks, like dairy products, fruit juices, and coconut water, are excellent sources of crucial electrolytes post-workout.

But, be mindful of added sugars. 

Try electrolyte Infusions

After intense exercise, replenishing electrolytes through food alone may not be feasible. 

Adding electrolyte drinks and supplements into your routine can help replenish and speed up rehydration. This will make sure your body can focus on building upon your hard work.

Cool Off

Sweating during exercise leads to water and electrolyte loss. After hydrating with electrolyte-infused fluids, a cold shower can cool your body and prevent further depletion of minerals.

Cooling off helps your body retain the electrolytes you've worked hard to restore.

Let Yourself Rest

While exercise is vital, rest periods are equally important for optimal recovery. Allowing your body time to recuperate after exertion maximises gains.

Embrace rest as a necessary part of your fitness routine, just like any other set of exercises.

Consume a Diet Rich in Electrolytes

A healthy diet remains the foundation of any effective fitness regimen.

After exercise, cooling off, and resting, consuming foods rich in electrolytes completes the replenishment process. These foods include…

  • Avocado
  • Milk
  • Broccoli
  • Yoghurt
  • Chicken
  • Turkey
  • Strawberries
  • Bananas
  • Tomatoes
  • Watermelon
  • Mixed fruit vegetable smoothies
  • Lentils

What you should look for in electrolyte powder

Before selecting the right electrolyte powder, it's important to understand why you need it and how it can support your specific goals.

Here's what you should look for…


Electrolyte levels can vary greatly in different powders. The main electrolytes to consider are sodium, potassium, magnesium, calcium, and chloride

For longer and more intense workouts, it's best to choose powder with higher sodium levels (500mg per serving or more).

Lower sodium levels (less than 500mg per serving) are suitable for low-intensity workouts. If you're supplementing for everyday hydration, a lower electrolyte level (around 250mg) should do the trick.


Not all electrolyte supplements contain carbohydrates. Those that do, especially those with a significant carb content (10g or more), are typically designed for longer workouts.

But, since you can't get enough carbohydrates from a regular diet, don't worry too much about a few grams of carbs in your electrolyte powder.


While fewer electrolyte supplements include caffeine, some still do. If you're a competitive athlete, make sure to check if caffeine is prohibited in your sport.

Otherwise, caffeine can be beneficial as a stimulant for intense workouts, but it's not essential in an electrolyte supplement.


Sugar added to electrolyte supplements is generally unnecessary as most diets already contain sufficient amounts of sugar.

Although sugar can enhance taste, it's not essential. Consider opting for supplements without added sugar to avoid unnecessary additional sugar intake.

What are the benefits of using electrolyte powder?

Oh, there’s plenty.

Electrolyte powder offers several advantages (1), including enhanced hydration, improved athletic performance, accelerated muscle and tissue recovery, and support for healthy cellular and nerve function. 

Enhances Hydration

The best electrolyte powders can be a valuable tool for improving hydration.

Electrolytes play a crucial role in maintaining fluid balance in the body, and consuming them daily can help keep you properly hydrated, which is important for overall health and wellbeing.

Additionally, your body can absorb electrolyte powders with ease, allowing for quick and efficient nutrient absorption.

This can be particularly beneficial (2) when you’re sick and experiencing fluid loss, which can lead to electrolyte imbalances. 

By mixing electrolyte powders into water or juice, you can replenish lost fluids and electrolytes.

Improves Athletic Performance

During training and sports, athletes not only lose electrolytes through sweat but also have an increased need for rapid muscle contraction and relaxation, nerve function, and enhanced cognitive function.

While mild dehydration usually doesn't lead to negative performance effects, moderate to severe levels can be risky (3).

For athletes, an electrolyte mix is preferable to plain water because they are excreted through sweat.

Replacing what is lost prevents muscle cramps during exercise and ensures better muscle and nerve reaction times.

While endurance athletes typically require increased fluid intake, drinking plain water alone can result in overhydration and hyponatremia.

This condition, characterised by low sodium levels, can cause symptoms such as confusion, nausea, delirium, coma, and even death.

Using electrolyte powders helps maintain fluid balance, preventing the symptoms of under- or overhydration.

Plus, regularly replenishing salt can decrease the risk (4) of developing cramps during exercise.

Promotes Tissue Recovery

To improve recovery after a demanding workout, injury, or surgery, it is crucial to replenish electrolytes for healing and hydration.

Electrolytes, particularly sodium, facilitate the movement of key nutrients to healing tissues through osmosis.

Plus, calcium, another important electrolyte, is involved in blood clotting and bone health (5), which are essential for healing post-exercise, injury, or surgery.

Regular use of electrolyte powders can support tissue and muscle recovery necessary after exercise or injury, aiding in the healing process.

Boosts Cellular Function

Electrolytes play a key role in maintaining cellular health by participating in various cellular functions. They’re also essential to ensure an adequate supply of these electrolytes to support optimal cell functioning.

They aid in the transport of essential nutrients into cells and facilitate the removal of waste products, enabling cells to operate efficiently.

Plus, electrolytes help reduce the workload on the kidneys and liver by assisting in the elimination of waste substances.


Prevents Heat Stroke

When you’re in hot environments, your body perspires to regulate your temperature. But, this sweating leads to the loss of essential minerals and electrolytes such as sodium, chloride, and small quantities of potassium, magnesium, and calcium.

So, it’s crucial to replenish these electrolytes, particularly when you are exposed to prolonged heat (6) and engaged in physical activities.

SmartTip: To avoid the risks of heat stroke and exhaustion, we advise that you gradually adapt to hotter temperatures.

What are the pros and cons of electrolyte powder?

Electrolyte powder commonly consists of sodium, potassium, calcium, phosphorus, and magnesium—while some variants of electrolyte powders may also include carbohydrates and additional vitamins.

Lots of us utilise electrolyte powders before, during, or after engaging in physical activities or sports. 

But, we recommend consulting with a healthcare provider to assess whether electrolyte powders are suitable for your specific needs.

We’ve put together some of the main pros and cons of consuming electrolyte powder.


  • One advantage of using electrolyte powders is the ability to control the amount used. You can easily adjust the quantity of powder as needed.
  • Electrolyte powders are convenient and can be easily customised. You can mix them into smoothies or juices, making them very versatile. 


  • It's important to note that although electrolyte powders taste good and aid in hydration, more is not always better. Overconsumption can occur if they are primarily used to increase water intake.
  • Electrolyte supplements, including powders, should be used only when necessary, such as after intense exercise, excessive sweating, or during illnesses associated with vomiting or diarrhoea. Using them for other purposes can pose potential issues. In fact, most individuals do not require electrolyte supplements if they maintain a balanced diet.
SmartTip: The recommended daily intake of sodium is 2,300 mg, whereas an average serving of electrolyte powder contains 335 mg of sodium. 

If you consume electrolyte powder throughout the day in addition to your regular sodium intake from food, you may exceed the recommended limit. So, be mindful.

Are there any risks associated with electrolyte powder?

Electrolyte powders are generally considered safe and have minimal to no side effects for most people, but it's important to evaluate your current intake of electrolyte-rich foods and beverages before adding them to your daily or weekly routine.

If you regularly eat bananas, yoghurt, avocado, coconut water, or spinach, for example, you might already be getting the minerals (7) found in electrolyte powders.

It's also crucial to be mindful of your sodium intake to avoid over-supplementation. The recommended daily sodium intake is 2,300mg, but some powders contain up to 1,000mg per packet.

SmartTip: If you have any underlying health conditions like kidney problems, high blood pressure, or diabetes, it's best to consult with your healthcare provider before using electrolyte powders. Certain health conditions can make it challenging to balance electrolytes without the help of supplements.

Over-supplementing with potassium, or hyperkalemia, can lead to serious heart problems— so maintaining appropriate electrolyte levels is essential.

Be mindful, too, that some medications like diuretics or blood pressure medications can interact with electrolyte powders, potentially causing harmful side effects or reducing their effectiveness.

Finally, some electrolyte powders may contain added sugars and calories, which could affect calorie intake and blood sugar levels for those seeking to manage them.

NOTE: It's essential to read the label and check the ingredients before using any dietary supplement.
