Zinc is an essential trace mineral that plays a role in over 100 enzymatic reactions in the body.

It functions to protect against oxidative damage, helps with wound healing, makes DNA, and helps with the formation of hemoglobin.

Zinc deficiency symptoms include frequent colds, leaky gut, consistent diarrhea, poor vision, infertility, thinning hair, stunted growth in children and slow healing wounds.

People most at risk for a deficiency in zinc include:

  • Vegetarians and vegans
  • Pregnant women
  • Endurance athletes
  • Alcoholics
  • People with gastrointestinal diseases
  • Those who over-consume iron supplements
  • People taking diuretic medications

If you are zinc deficient then animal foods are better sources than plant foods like vegetables.
