Our bodies can heal and preserve bodily function when infected or injured. This complex system is known as the immune system and its well-being can be defined as immune health. This system relies on a balance of physical barriers such as skin, inflammatory and cellular responses, and cellular adaptation, maintaining optimal immune health. When this balance is disrupted, the immune system is compromised, and poor health outcomes such as disease are more likely.
As with other bodily functions, nutrition has a role to play in immune health, with specific vitamins and minerals playing an important role in supporting the function of the immune system. Such micronutrients can reduce the likelihood of an illness or promote healing. Selenium ACE+D combines Selenium with Zinc and 4 vitamins selected for their scientifically proven ability to support everyday immune health.
Which nutrients support immune health?
Selenium
Selenium is a trace mineral involved in the normal function of the immune system. A selenium deficiency has been linked to immune cells not functioning effectively. Selenium is incorporated into immune-regulating proteins called selenoproteins.[1] It also acts as an antioxidant, protecting cells from oxidative stress caused by free radicals. Free radicals are unstable molecules that damage cells and contribute to inflammation. Selenium is also important for thyroid function, and research suggests that thyroid hormones can influence the immune system.[2]
Vitamin A
Vitamin A plays a multifaceted role in supporting a healthy immune system.[3] Vitamin A is crucial for maintaining the health of mucous membranes, which line the surfaces of our respiratory, digestive, and urinary tracts. These membranes act as our first line of defence, preventing pathogens from entering the body.[4] Vitamin A is also involved in the development and function of immune cells.
Vitamin D3
Vitamin D is a fat-soluble vitamin that our bodies can produce when exposed to UV radiation from the sun. However, due to the societal norm of spending long periods sitting inside and out of the sun, many people are often deficient. The NHS advises supplementing the diet with 10μg of vitamin D a day.[5] Vitamin D is involved in immune system function, with high intakes being liked to fewer infections.[6]
Vitamin E
Vitamin E is a powerful antioxidant, protecting cells from oxidative stress. By neutralizing free radicals, vitamin E helps keep immune cells functioning effectively, allowing them to fight off invaders like bacteria and viruses. Studies with high-dose Vitamin E have shown a small improvement in markers of immunity.[7]
Vitamin C
Vitamin C acts as a cofactor for various enzymes, notably enzymes involved in collagen synthesis, and as an antioxidant.[8] Its role in collagen synthesis is important, as collagen is a structural protein found in skin, the body’s physical barrier and first line of defence against pathogens. Vitamin C also contributes to the immune system as it plays a role in the production of immune cells.[9]
Zinc
Zinc is an important mineral involved in over 300 enzymatic reactions in the body, including those involved in the immune system.[10] Studies have found high doses of Zinc to be beneficial in reducing the duration and symptoms of colds and upper respiratory infections.[11]
