Magnesium RBC
Muscle and nerve function. Essential for muscle function and recovery.
What it tests: The amount of magnesium inside your cells, where it actually does its work.
Why it is important: A more accurate read on true magnesium status than the standard serum test. Many people with classic deficiency symptoms (cramps, poor sleep, anxiety, fatigue) get told their magnesium is fine when it is not.
