How to Support Your Immune System

A healthy immune system relies on a balance of essential nutrients. We believe in food first, followed by supplementing the nutrients that are increasingly under-represented or omitted from our modern diet and lifestyle. For many, targeted immune system supplements can help fill nutritional gaps and support overall wellbeing.



  • Vitamin D - Vitamin D supplements contribute to the normal functioning of the immune system and help maintain healthy bones and muscles.
  • Vitamin C - Vitamin C supplements support the body’s defence through cellular functions. As a water-soluble vitamin, it cannot be stored, so a regular supply is important.
  • Iron - Iron supplements are essential for the formation of immune cells and healthy red blood cells, helping the body carry oxygen efficiently.
  • Vitamin B - Vitamin B supports red blood cell production and energy metabolism, which are vital for maintaining normal immune function.
  • Selenium - Selenium oral sprays help to lower oxidative stress in the body, which reduces inflammation and supports immunity.
  • Zinc -Zinc supplements activate enzymes that help break down pathogens and support normal immune system function.


Foods to Support The Immune System

A nutrient-rich diet is the first step in maintaining strong immunity. Foods such as leafy greens, lean meats, fish, eggs, nuts, seeds, and citrus fruits provide many of the vitamins and minerals listed above. Supplements for immune system support can complement your diet, especially when certain nutrients are difficult to get from food alone.

Your immune system relies on a network of cells, tissues, and organs to defend against harmful germs. Low vitamin and mineral levels can reduce your body’s ability to fight infection. Immune system supplements provide essential nutrients like vitamin D, C, zinc, and iron to help maintain balanced nutrition and support your body’s natural defences.

The most effective immune system supplements target common nutrient gaps, including vitamin D, vitamin C, zinc, selenium, and iron. These nutrients support the body’s natural defences and help maintain balanced immune function. Supplements work best alongside a healthy lifestyle, including a nutrient-rich diet, regular rest, and exercise.

There’s no single “most powerful” immune booster — a strong immune system relies on a balanced diet, adequate sleep, regular exercise, and stress management. Key nutrients include vitamin D, vitamin C, zinc, selenium, and iron, found in foods like citrus, leafy greens, nuts, and fish. Supplements can help fill gaps where diet falls short.

Maintain a strong immune system through a healthy lifestyle. Eat a balanced diet rich in fruits, vegetables, and lean protein; stay physically active; get adequate sleep; manage stress; and avoid smoking or excess alcohol. Immune system supplements can help fill nutritional gaps and support your body’s natural defences.
