Magnesium (Elemental Mg) vs. Vitamin C (L-Ascorbic Acid)
Comparing 2 standards across 9 specifications. 9 key differences identified.
Comparing:
Magnesium (Elemental Mg)
Vitamin C (L-Ascorbic Acid)
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).
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.
