Magnesium

What it tests for:
This test measures magnesium levels inside your red blood cells (RBCs) — providing a more accurate picture of your long-term magnesium status compared to standard serum tests.

Why it matters:

• Magnesium is essential for over 300 enzymatic reactions in the body, including energy production, muscle and nerve function, blood pressure regulation, and heart rhythm stability

• Low magnesium may contribute to fatigue, muscle cramps, headaches, poor sleep, anxiety, and irregular heartbeat

Who it’s for:
Recommended for those with symptoms of deficiency, high stress, chronic fatigue, poor sleep, or conditions like PMS, migraines, or blood pressure issues. Also helpful for athletes or those taking medications like diuretics or PPIs.
