Magnesium (Elemental Mg) vs. Sodium (Elemental Na)
Comparing 2 standards across 11 specifications. 11 key differences identified.
Comparing:
Magnesium (Elemental Mg)
Sodium (Elemental Na)
Magnesium is an essential macromineral required as an enzymatic cofactor in over 300 biochemical reactions including ATP synthesis, DNA replication, and neuromuscular transmission. Adult RDA is 400–420mg (men) / 310–320mg (women).
Sodium is the principal extracellular cation (135–145 mEq/L extracellular), maintaining extracellular fluid volume, plasma osmolality, and driving secondary active transport. Adequate Intake (AI) is 1,500 mg/day, with a Chronic Disease Risk Reduction (CDRR) limit of 2,300 mg/day.
