A mineral needed for muscle and nerve function, blood sugar control and bone. Most of the body's magnesium sits inside cells and bone, so the blood test shows only a small share.

Why trials measure it. Magnesium supplement trials report it to confirm absorption, even though serum magnesium reflects only part of the body's stores.

About this marker: Magnesium Blood Test (MedlinePlus, U.S. National Library of Medicine).

Evidence states come from published human studies found in PubMed and OpenAlex and read by a model pipeline. "Not studied" means no usable human study was found for this marker, which is a gap, not a negative result. Every result links its studies so you can check it.
