Intracellular Magnesium

What is Intracellular Magnesium?

Intracellular Magnesium refers to the magnesium located within the body's cells. This is important because the majority of magnesium in the body resides intracellularly, where it is essential for numerous cellular processes, including energy production, DNA synthesis, and the regulation of muscle and nerve functions.

Why should Intracellular Magnesium be tested?

Measuring intracellular magnesium can provide a more accurate picture of a person's magnesium status than a standard blood test. This can be particularly useful for diagnosing masked magnesium deficiencies, which are not always visible in serum magnesium levels, especially in conditions such as chronic fatigue, muscle cramps, or cardiac arrhythmias.

What does it indicate?

The concentration of intracellular magnesium can offer insight into cellular health and functioning. It assists in assessing the risk or presence of certain health issues associated with magnesium deficiency, even if blood levels appear normal.

What does a high intracellular magnesium level mean?

A high intracellular magnesium level is rare and may indicate excessive magnesium intake through diet or supplements. It requires monitoring to prevent potential negative health effects, such as kidney problems.

What does a low intracellular magnesium level mean?

A low intracellular magnesium level may indicate a deficiency at the cellular level, which is more severe than a deficiency measured in the serum. This can lead to various symptoms and conditions, including muscle weakness, elevated blood pressure, cardiac issues, and reduced insulin sensitivity.
