Electrolytes are vital minerals present in blood, sweat, and urine. They have an electric charge and play a crucial role in various body functions. Common electrolytes include sodium, potassium, calcium, and magnesium, along with bicarbonate, chloride, and phosphate.
They have a huge role in optimal health and performance beyond just hydration.
They play a critical role in maintaining the balance of fluids between the intracellular (inside the cell) and extracellular (outside the cell) environments (REF).
This balance is crucial for the functioning of many bodily processes, including muscle contraction and the transmission of nerve impulses, which are essential for heart function, muscle movements, and neurological processes.
Electrolytes are pivotal in regulating the body's hydration levels and are integral to the acid-base balance that is vital for normal cellular activities.
In this article, we will delve deeper into the science and application of electrolytes.

By understanding the significance of electrolytes, you can better appreciate their role in keeping you healthy and how to manage their levels to optimise your physical and mental performance.
Electrolytes are substances that, when dissolved in water, dissociate into ions, making the solution capable of conducting electricity. This property is fundamental to understanding the definition and characteristics of electrolytes, and their significance, especially in the context of the human body and hydration.
When a compound, typically a salt, acid, or base, dissolves in water, it splits into small, electrically charged particles known as ions. These ions are either positively charged (cations) or negatively charged (anions). For example, common table salt (sodium chloride, NaCl) when dissolved in water, dissociates into sodium ions (Na+) and chloride ions (Cl-). These free-moving ions enable the solution to conduct electricity, a characteristic trait of electrolytes.
Electrolytes are thus defined as substances that produce ions when dissolved in a solvent like water. Their key characteristics include their ability to conduct electricity, regulate fluid balance, and maintain a charge balance both inside and outside of cells. The presence of these ions in body fluids is crucial for various physiological functions (REF).
In the human body, electrolytes are vital for numerous functions. They help regulate nerve and muscle function, hydrate the body, balance blood acidity and pressure, and help rebuild damaged tissue.
The body's hydration level is intricately linked with electrolytes. They ensure that the right amount of water is maintained within cells, blood plasma, and bodily fluids. This balance is critical for the proper functioning of our biological systems (REF).
Let's explore the key electrolytes, their roles in the body, and their recommended daily intake (REF).
Sodium (Na+)
Sodium is essential for fluid balance, nerve function, and muscle contraction. It plays a pivotal role in regulating blood pressure and volume. The recommended daily intake of sodium is less than 2,300 milligrams for adults, but this can vary depending on age, health status, sweat rate and physical activity levels.
Potassium (K+)
Potassium is vital for heart function, muscle contraction, and maintaining a healthy nervous system. It also helps regulate fluid balance and blood pressure. The recommended daily intake for potassium is around 3,500-4,700 milligrams for adults.
Calcium (Ca2+)
Calcium is well-known for its role in building and maintaining strong bones and teeth. It's also crucial for blood clotting, muscle contraction, and nerve signaling. Adults generally require about 1,000 milligrams of calcium per day, though this can increase for older individuals.
Magnesium (Mg2+)
Magnesium supports over 300 enzymatic reactions, including energy creation, protein formation, and muscle movements. It also plays a role in nervous system regulation. The recommended daily intake of magnesium is 400-420 milligrams for men and 310-320 milligrams for women.
As we will cover later, a large number of electrolyte products will contain very small amounts of magnesium. Our performance hydration sachets contain 100mg of magnesium malate to help you get closer to optimal levels.
Chloride (Cl-)
Chloride, often found in salt alongside sodium, helps maintain fluid balance and is essential for producing stomach acid (hydrochloric acid). The recommended daily intake is about 2,300 milligrams for adults, but this can vary based on individual needs and health conditions.
Phosphate (HPO4^2-)
Phosphate is important for the formation of bones and teeth. It's involved in energy production, muscle function, and the formation of DNA and RNA. Adults should aim for about 700 milligrams of phosphate per day.
Electrolytes are key for hydration, maintaining fluid balance through osmosis, and preventing dehydration. They are crucial during exercise for replenishing lost minerals and supporting muscle function.
Our Performance Hydration Electrolyte Sachets contain a blend of essential electrolytes beneficial for exercise performance and hydration. In this section we will cover the role electrolytes play in hydration and performance.
Role of Electrolytes in Maintaining Fluid Balance
Electrolytes play a crucial role in maintaining fluid balance within the body. They help regulate the distribution of water in the intracellular and extracellular spaces. This balance is essential for proper cell function, nerve conduction, muscle contraction, and maintaining blood pressure.
Osmosis and Water Regulation:
Osmosis is the process by which water moves across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration. In the body, this process helps regulate the concentration of electrolytes and ensure that the fluid levels inside and outside the cells are balanced.
Electrolytes, particularly sodium and potassium, play a key role in this process by maintaining the osmotic pressure and regulating the movement of water across cell membranes.
Electrolyte Imbalance and Dehydration:
An electrolyte imbalance, often caused by excessive fluid loss from sweating, vomiting, or diarrhea, can lead to dehydration.
When the body loses water and electrolytes, it disrupts the balance necessary for proper function of cells, tissues, and organs. This can result in symptoms such as dizziness, muscle cramps, and confusion.
During prolonged or intense physical activity, especially in hot environments, the body can lose significant amounts of electrolytes through sweat. In these situations, replenishing lost electrolytes is important for maintaining proper hydration and supporting muscle function.
Athletes and individuals engaging in strenuous exercise may benefit from consuming electrolytes or foods to help replace the lost electrolytes and maintain fluid balance.

Electrolytes are minerals in your body that have an electric charge. They are found in your blood, urine, and body fluids. Key electrolytes include sodium, potassium, calcium, bicarbonate, magnesium, chloride, and phosphate. These minerals help balance the amount of water in your body, balance your body's acid/base (pH) level, move nutrients into your cells, move wastes out of your cells, ensure that your nerves, muscles, the heart, and the brain work the way they should.
For athletes or anyone that is training frequently, electrolytes are particularly important. They regulate nerve and muscle function, hydrate the body, balance blood acidity and pressure, and help exercise performance. During physical activities, the body loses electrolytes through sweat, particularly sodium and potassium, which can lead to electrolyte imbalances. This imbalance can cause muscle cramping, fatigue, nausea, and a reduction in cognitive function, all of which can negatively impact athletic performance. Maintaining electrolyte balance is crucial for anyone looking to improve their exercise performance.
Yes, it's possible to get enough electrolytes from food alone. Most people can maintain their electrolyte balance through a normal diet. Foods rich in electrolytes include fruits and vegetables like bananas, oranges, and sweet potatoes, dairy products, and nuts. However, individuals with certain health conditions, those who train regularly, have a high sweat rate or those exposed to prolonged heat might need additional electrolyte intake. This is where supplementation may be beneficial.
Having too many electrolytes, known as hypernatremia (high sodium) or hyperkalemia (high potassium), can be harmful. It can lead to dehydration, seizures and heart rhythm disturbances. This is usually due to excessive supplementation rather than excessive intake through foods.
Electrolyte drinks can be better than water for hydration in certain circumstances, such as prolonged physical activity, excessive sweating, or heat exposure. They help replenish lost minerals more effectively than water. However, for regular daily hydration, water is usually sufficient. It is all about balance. Excessive consumption of electrolyte drinks when they're not needed can lead to an imbalance but drinking a lot of water without adequate electrolyte intake can also create an issue.
Yes, certain diets can lead to electrolyte imbalance. For instance, diets with excessive or too little salt can disrupt electrolyte balance. Diets lacking fruits and vegetables may put you at risk of low potassium and magnesium. Diets low in potassium or magnesium may also lead to imbalances, especially in athletes or those with certain health conditions.
The best natural sources of electrolytes are varied and include fruits like bananas, oranges, and watermelon; vegetables like spinach, sweet potatoes, and avocados; dairy products like milk and yogurt; nuts and seeds; and beans and lentils. These foods provide a balanced intake of different electrolytes, which is beneficial for maintaining overall health.
