What is the normal range for magnesium levels?

The normal range for magnesium levels in the blood is typically between 0.65 and 1.05 mmol/L. This range is important for various physiological functions including neuromuscular transmission, enzyme activity, and maintaining normal heart rhythm. Magnesium is an essential mineral and an electrolyte that plays a role in over 300 enzymatic reactions in the body, making it crucial for overall health.

Understanding abnormal magnesium levels is equally important, as hypomagnesemia (low magnesium levels) can lead to symptoms such as muscle cramps, seizures, and arrhythmias, while hypermagnesemia (high magnesium levels) can result in lethargy, respiratory failure, and cardiac arrest. Therefore, recognizing that the core normal range is between 0.65 and 1.05 mmol/L helps healthcare professionals assess and manage patients effectively.
