Vitamin K1 (Phylloquinone) vs. Zinc (Elemental Zn)

Comparing 2 standards across 10 specifications. 10 key differences identified.

Comparing:
Vitamin K1 (Phylloquinone)
Zinc (Elemental Zn)
Vitamin K1 (Phylloquinone) →

Vitamin K1 is a fat-soluble naphthoquinone synthesized by photosynthetic plants. Adequate Intake (AI) is 120µg (men) / 90µg (women), acting as an essential cofactor for gamma-glutamyl carboxylase in blood clotting and osteocalcin bone mineralization.

Zinc (Elemental Zn) →

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.
