Immune support, especially vitamin C, is historically based on supplementation in scurvy in early times. It has since been established that the immune system is a complex, integrated system that needs multiple specific micronutrients, including vitamins A, D, C, E, B6, and B12, folate, zinc, iron, copper, and selenium. Each of these play a vital role at every stage of the immune response.
Adequate amounts of these are essential; however, daily intakes necessary to support immune function may be higher for certain populations or individuals if there is:
- a low dietary intake,
- an increased requirement (e.g., infection, stress & pollution exposure)
- poor absorption due to genetic variations,
- decrease stores within the body.
Sometimes even marginal deficiency may impair immunity, depending on each individual.
WHAT WE DO KNOW is that a clean, healthy diet that consists of all the necessary nutrients will improve overall health and wellness, including a healthy immune system, that limits risk for disease.
Improving diet remains the first call to action!
Micronutrients with the strongest evidence for immune support are vitamins C and D and zinc.
Evidence now indicates that supplementation with multiple micronutrients with immune-supporting roles may improve immune function and reduce the risk of infection.
What else do we know?
- Don’t smoke
- Eat a diet high in fruits and vegetables.
- Exercise regularly.
- Maintain a healthy weight.
- If you drink alcohol, drink only in moderation.
