Nutrition and Immunity

Nutrition and Immunity - GNC India

The immune system is constantly working to protect the body from infection, injury, and disease. White blood cells are the cells of the immune system. There are total 6 types of WBC’s which travel through the body inside lymph vessels, which are in close contact with the bloodstream.

The immune system protects you from three major reasons for developing infections and diseases:

  • OXIDATIVE DAMAGE: Certain immune cells produce a concentrated burst of reactive oxygen species (ROS), damaging substances that help kill invading organisms.

Important nutrients:

  • Vitamin C
  • Vitamin E
  • Iron
  • Zinc
  • Copper
  • Selenium


  • Prolonged and continuous exposure to ROS can lead to damage and disease.

The listed antioxidant nutrients protect immune cells and keep the oxidative burst in check.

  • PROLIFERATION: Refers to an increase in the number or amount of something. The immune system is constantly producing cells, chemicals, and proteins to carry out its functions. When it encounters a foreign invader, it ramps up production to respond as needed.

Important nutrients:

  • Vitamin A
  • Vitamin D
  • Folate
  • Vitamin B12
  • Vitamin B6
  • Iron
  • Zinc


  • Proliferation requires energy, building blocks, and cofactors to produce the many cells and substances needed to mount an effective immune response.
  • The listed micronutrients have essential roles in the production and development of all new cells in the body, including immune cells.


  • Isolates the injured or infected area.
  • Helps deliver immune cells, chemical messengers, and antibodies to sites of injury or infection.

Important nutrients:




  • Inappropriate activation or the inability to turn off inflammation can lead to tissue damage and chronic disease.
  • EPA and DHA have anti-inflammatory activity that can help keep inflammation in check.
