Question

what micronutrient enhances non-heme iron absorption? a. copper b. potassium c. sodium d. vitamin c e. all of the above

Answer 1

Copper, zinc, and B vitamins enhance non-heme iron absorption.

Step-by-step explanation:

Copper enhances non-heme iron absorption. Copper is a trace mineral that plays a crucial role in the synthesis of hemoglobin. Hephaestin and ceruloplasmin, two plasma proteins that contain copper, enable the absorption and oxidation of iron, allowing it to be transported to body cells for heme synthesis. Zinc is another micronutrient that facilitates the synthesis of the heme portion of hemoglobin. B vitamins like folate and vitamin B12 are also important for the synthesis of new cells, including erythrocytes.
