Glenn's Key take aways :
  • Electrolytes are minerals—including sodium, potassium, and calcium—that regulate fluid balance and nerve function.
  • They are available in drinks, powders, tablets, and natural foods like fruits and vegetables.
  • When imbalanced, they can lead to fatigue, muscle cramps, and dehydration.

What Are Electrolytes?

Electrolytes are electrically charged minerals crucial for:

  1. Hydration: Regulate water levels in and out of cells.
  1. Nerve and Muscle Function: Support communication between nerves and muscle contraction.
  1. Acid-Base Balance: Maintain the body's pH levels.

‍

Common electrolytes include:

  1. Sodium: Found in salt and processed foods.
  1. Potassium: Found in bananas, oranges, and leafy greens.
  1. Calcium: Found in dairy products and fortified foods.
  1. Magnesium: Found in nuts, seeds, and whole grains.

Learn more about electrolytes and their functions at the NHS Overview on Minerals.

Conclusion

Electrolytes are essential for maintaining hydration, nerve and muscle function, and overall body balance. Ensuring an adequate intake through a balanced diet, hydration, and supplementation when necessary can prevent imbalances that lead to fatigue, cramps, and other health issues. By understanding their role and recognising the symptoms of imbalance, you can support your body’s optimal function and overall well-being.
