Side-by-Side Comparison
Essential Vitamins & Minerals
Sodium (Elemental Na) vs. Vitamin C (L-Ascorbic Acid)
Comparing 2 standards across 11 specifications. 11 key differences identified.
Comparing:
Sodium (Elemental Na)
Vitamin C (L-Ascorbic Acid)
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.
Vitamin C is a water-soluble electron donor and antioxidant essential for collagen proline/lysine hydroxylation, non-heme iron absorption, and immune phagocyte function. Adult RDA is 90mg (men) / 75mg (women), with a Tolerable Upper Limit of 2,000mg/day.
