Medically reviewed by SASI Medical Review Board.
The immune system protects the body from infections and illnesses by identifying and neutralizing harmful pathogens such as bacteria, viruses, and fungi. Zinc contributes to this defence by:
- Supporting the development and activation of immune cells, including T-cells and natural killer cells
- Helping to reduce inflammation, which can otherwise damage tissues and impair immune function
- Assisting in wound healing and tissue repair, which are critical for recovery from injuries and infections
Many foods contain zinc, including meat, seafood, dairy, nuts, and legumes. However, some individuals may not get enough zinc from diet alone due to dietary restrictions, health conditions, or increased physiological needs. In such cases, supplements might be considered to support immune health, but it is important to use them responsibly and under medical guidance.
Overall, zinc is a vital nutrient that helps the immune system stay strong. Learning about its benefits and sources can empower Canadians to protect their health year-round, especially during cold and flu seasons or times of increased vulnerability.

Zinc for immune support – Causes and risk factors affecting zinc and immunity
Understanding the causes and risk factors of weakened immunity helps guide effective prevention and treatment. Several elements influence immune function, including age, sex, existing health conditions, and lifestyle choices.
Age and sex
Immune response naturally declines with age, making older adults more vulnerable to infections and slower to recover. Additionally, sex differences affect immunity; for example, females often have stronger immune responses than males, which can influence disease susceptibility and vaccine responses.
Comorbidities
Chronic illnesses such as diabetes, heart disease, autoimmune disorders, and chronic kidney disease can impair immune function. These conditions often cause persistent inflammation or disrupt normal immune regulation, increasing the risk of infections and complicating recovery.
Lifestyle factors
Several lifestyle habits impact immune health and zinc status:
- Poor nutrition, including low intake of essential nutrients like zinc for immune support, can compromise immune defences.
- Insufficient sleep, which reduces the body’s ability to fight pathogens and recover from illness.
- High stress levels, known to suppress immune responses through hormonal pathways.
- Smoking and excessive alcohol consumption, both of which damage immune cells and impair nutrient absorption.
- Lack of regular physical activity, which can weaken immune defence mechanisms and overall health.
Addressing these risk factors through balanced nutrition, stress management, and healthy habits can strengthen immunity and reduce illness risk. Incorporating zinc-rich foods and maintaining a healthy lifestyle are key components of immune support.
