Potassium is a mineral present throughout your body, crucial for your health. It is among the most plentiful electrolytes, which are electrically charged minerals in your body, aiding your nerves to operate and muscles to contract. It helps maintain a regular heartbeat, conducts nerve impulses, and facilitates the movement of nutrients and other compounds in and out of cells. Predominantly, potassium is housed inside cells across your body, and its level in the liquid component of blood is regulated by the kidneys. A significant portion of the recommended potassium intake is obtained from the food we consume.

A normal potassium level signifies that your overall electrolyte balance is maintained, leading to healthy fluid balance, pH balance, nerve function, and muscle function. Such knowledge about the function and importance of potassium can motivate us to ensure we're getting enough of this essential mineral in our diet, enhancing our overall health and well-being.

Potassium, in concert with other electrolytes such as sodium and chloride, plays a crucial role in controlling fluid balance, pH balance, and functions reliant on conduction capacity like muscle and nerve functions. Consequently, measuring potassium levels can be used to monitor these functions and various conditions that influence them. Examples of conditions where potassium monitoring is particularly relevant include high blood pressure, kidney disease, diabetes, and heart disease.

Low potassium levels, otherwise known as hypokalaemia, often indicate an increased loss of potassium through the kidneys via certain diuretics. Excessive diarrhoea, vomiting or severe burns may also result in reduced potassium levels. Symptoms of low potassium levels can vary and are always individual, but several common symptoms are observed in men with reduced potassium levels, including:

Irregular heart rhythms




Digestive issues such as constipation and bloating

When you lose water from your body, you also lose some essential minerals and electrolytes along with it. To maintain your health, you need to replace the potassium you've naturally lost, just as you would the water.

So, the crux of the matter is, we rehydrate to keep our bodies as healthy as possible. Anything less, and we feel unwell. By ensuring that potassium is present in our system, we guarantee that rehydration keeps us performing at our best. As we learn more about the functions and importance of potassium, we are empowered to make healthier choices that promote well-being.
