Magnesium (RBC)

Magnesium is a foundational mineral for energy, sleep, muscle function, and stress response. RBC Magnesium measures how much is stored inside your red blood cells — not just floating in your blood — making it way more useful for spotting chronic deficiencies. If you’re training hard, under stress, or not sleeping great, low magnesium can quietly wreck your progress.
