Vitamin D is another Immune Boosting vitamin that is important for maintaining a healthy immune system. Vitamin D is a fat-soluble vitamin that’s stored in the liver and fatty tissues. It can be gathered from food sources, such as eggs, fish, and fortified dairy products.
However, the best source of vitamin D is exposure to sunlight. The body produces vitamin D when the skin is exposed to ultraviolet B (UVB) rays from the sun. We’re taking natural sunlight here, not sunbeds!
Vitamin D helps to regulate the immune system and has been shown to reduce the risk of respiratory infections.
Vitamin D plays big role in regulating the immune system overall and is another essential vitamin for a healthy immune system.
There is some evidence that suggests that vitamin D deficiency may be linked to an increased risk of respiratory infections, such as the flu as well as possibly even Covid 19. One study found that people who took a vitamin D supplement were less likely to get the flu than those who did not take a supplement.
Vitamin E is an Immune Boosting vitamin that acts as an antioxidant. Antioxidants help to protect your cells from damage and can help to improve your immune system function.
Vitamin A supports the body’s natural defences by helping to produce white blood cells in the body as well as antibodies all in a bid to fight off infection. Vitamin A also helps to regulate the Immune system. Deficiencies in vitamin A have been linked to increased susceptibility to infections, such as measles as well as diarrhea.
Vitamin A is found in a variety of foods and vegetables across the board, including dark leafy greens such as chard or spring greens for us in the UK.
