A robust immune system is fundamental to good health. A strong immune system is needed to help build resilience to any opportunistic bacteria, viruses or illness we may face all year round. Discover 'Signs your body is fighting an infection'.
Vitamin D3
Vitamin D3 in its biologically active form, will help support your body’s immune defences. Vitamin D3 is recommended by Public Health England during the Autumn (ideally from October) through to Spring (April), while an intake of Vitamin D3 is also recommended, depending on your individual needs throughout the year.(4-5) If you wondering if you're deficient in Vitamin D, learn more about the signs of Vitamin D deficiency.

How Zinc supports the immune system
Zinc is an essential mineral that must be obtained through the diet. The body has no particular mechanism for storing Zinc and therefore a regular intake of small amounts of Zinc through diet or supplements is required to meet the body’s needs so it can function optimally and remain healthy. Learn more on why Zinc is so important for your immune system.
Zinc deficiency is more likely among:
- Vegetarians and vegans
- Those who are pregnant or breastfeeding women
- Those with an alcohol use disorder
- Those who suffer from gastrointestinal disorders such as IBD (Inflammatory Bowel Disease). Learn more in ‘What is IBD’.
In vegetarian diets, the bioavailability of Zinc is often lower, because large amounts of legumes and wholegrains are often consumed. These foods contain compounds called ‘phytates’ which can bind to Zinc and prevent its absorption.
Meat contains high amounts of bioavailable Zinc, but as we are slowly trying to reduce our consumption of animal produce, be it for health or sustainability reasons, we may as a result be lacking Zinc. If you are a vegetarian or vegan, there is a higher risk you will have lower dietary intakes of Zinc.
