Introduction
The human body contains numerous types of electrolytes, each with its own normal reference range. The normal serum potassium level is 3.5–5.5 mmol/L; the normal serum sodium level is 135–145 mmol/L; the normal serum calcium level is 2.25–2.75 mmol/L; and the normal serum chloride level is 98–106 mmol/L.
When discussing sports nutrition, the term “electrolytes” frequently arises. Even if you are not an athlete, electrolytes play a vital role in maintaining overall health. So, what are the normal reference ranges for electrolytes?
Normal Electrolyte Reference Ranges
The human body contains numerous types of electrolytes, each with its own distinct normal range. The normal serum potassium level is 3.5–5.5 mmol/L; serum sodium, 135–145 mmol/L; serum calcium, 2.25–2.75 mmol/L; serum chloride, 98–106 mmol/L; serum phosphorus, 0.96–1.80 mmol/L; and serum magnesium, 0.65–1.15 mmol/L.
Electrolytes in the human body refer to various inorganic and organic substances—specifically, inorganic compounds and certain organic compounds existing in ionized form—collectively termed “electrolytes.” Key electrolytes include potassium, sodium, chloride, calcium, and magnesium.
Electrolyte imbalances can lead to various clinical disorders. For example, abnormally high or low serum potassium levels are termed hyperkalemia and hypokalemia, respectively. Hypokalemia commonly results from inadequate intake or excessive loss. Correction of hypokalemia is essential, as it may cause widespread symptoms affecting skeletal muscle, cardiac function, and the nervous system. We hope this information is helpful to you!
