Vitamin C (L-Ascorbic Acid) vs. Zinc (Elemental Zn)
Comparing 2 standards across 9 specifications. 9 key differences identified.
Comparing:
Vitamin C (L-Ascorbic Acid)
Zinc (Elemental Zn)
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.
Zinc is an essential trace mineral serving as a structural component in over 2,000 transcription factor 'zinc finger' proteins and catalytic cofactor for 300+ enzymes. Adult RDA is 11mg (men) / 8mg (women), with a Tolerable Upper Limit of 40mg/day.

Copper Balance Warning
|
— | High zinc stimulates intestinal metallothionein which binds copper, risking microcytic anemia if copper is unsupplemented |
