Serum Magnesium

Serum magnesium is the blood levels of magnesium. While an acute spike results after magnesium supplementation, blood levels tend to be a poor predictor of magnesium status (erythrocytes are better) but are associated with the ability of magnesium to reduce blood pressure.

Human Effect Matrix

The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect serum magnesium
Grade Level of Evidence
Robust research conducted with repeated double-blind clinical trials
Multiple studies where at least two are double-blind and placebo controlled
Single double-blind study or multiple cohort studies
Uncontrolled or observational studies only
Level of Evidence
? The amount of high quality evidence. The mo re evidence, the more we can trust the results.
Outcome Magnitude of effect
? The direction and size of the supplement's impact on each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
Consistency of research results
? Scientific research does not always agree. HIGH or VERY HIGH means that most of the scientific research agrees.
Notes
grade-b Magnesium Notable High See all 6 studies
Has the capacity to increase serum magnesium stores, but this is somewhat unreliable and may be dependent on the person being deficient in magnesium prior to supplementation

All comparative evidence is now gathered in our ​A-to-Z Supplement Reference.
