We often hear about zinc for immune health, but why is it in high demand and why does it seem so important?
Zinc is necessary in almost all phases of immunity when our bodies fight pathogens, but also the damage caused by oxidative stress and toxins.

Here are some of these functions:

  • Antioxidant properties that can decrease the amount of reactive oxygen species
  • Allows the production of IgG type antibodies
  • Encourages the creation of antimicrobial substances which inhibits the growth of pathogens.
  • Promotes proliferation and also, differentiation of cells of innate immunity and encourages cytotoxic activity (against viruses).
  • Maintains the integrity of the physical and chemical barrier of the gastrointestinal mucosa, but also of the respiratory tract ... This role helps limit the spread of pathogens in the body.
  • Promotes the activity of T cells, immune cells that adapt to new pathogens presented to the body and creates a memory so as not to forget who these microorganisms are possibly pests.

Zinc is important in immunity, but would have much broader functions such as an aid in the control of type II diabetes, support in depression or, in age-related macular degeneration.
