Summary
New biomarkers are needed to accurately assess magnesium (Mg) nutritional status. Current Mg measurements in serum and urine may not reflect biochemical changes, necessitating the identification of novel functional biomarkers.
Area of Science:
- Biochemistry
- Nutritional Science
- Biomarker Discovery
Background:
- Functional biomarkers for nutrient status are crucial for assessing health.
- Current magnesium (Mg) measurements (serum, urine) may not accurately reflect Mg nutritional status.
- Existing biomarkers often derive from enzymatic processes measurable in biological fluids.
Purpose of the Study:
- To highlight the need for improved biomarkers of magnesium nutritional status.
- To identify novel biomarkers reflecting Mg's role in biochemical processes.
- To evaluate potential biomarkers in both human and animal models.
Main Methods:
- Review of current Mg assessment methods and their limitations.
- Identification of potential functional biomarkers linked to Mg-dependent pathways.
- Consideration of factors influencing biomarker concentration and reaction.
Main Results:
- Current total or ionized magnesium measurements may not reliably indicate nutritional status.
- Potential biomarkers include Na/K ATPase, thromboxane B2, C-reactive protein, and endothelin-1.
- Further research is required to identify and validate new Mg biomarkers.
Conclusions:
- There is a critical need for validated functional biomarkers of magnesium nutritional status.
- Novel biomarkers should reflect Mg's involvement in cellular biochemical processes.
- Future research must identify and evaluate these biomarkers across species and influencing factors.
