Magnesium is an essential mineral involved in over 300 enzymatic reactions, including energy production, DNA repair, and inflammation regulation—all processes linked to aging. However, the provided context does not contain direct evidence for a specific effect of magnesium on longevity. Some observational studies suggest a possible association between magnesium status and telomere length, but the evidence is mostly mechanistic or correlational. Deficiency can negatively impact cardiovascular health and insulin sensitivity, which may indirectly affect aging. Still, magnesium is not a proven longevity supplement. Supplementation should be based on measured deficiency, not as a blanket anti-aging strategy. Blood or DNA tests can indicate individual needs but do not replace medical advice.
