According to a study published in the Journal of Allergy and Clinical Immunology, the nose is the most susceptible to viral infections and decreased immunity when the weather turns cold. Here are some important vitamins that can help boost the body's immunity:
Vitamin C
According to research published in the journal Cureus, vitamin C is considered the most important micronutrient for immune function. It is a key antioxidant that supports the production and function of white blood cells, especially phagocytes and lymphocytes, which help fight infection. Vitamin C also strengthens the skin barrier, which acts as a line of defense against pathogens.
Vitamin D
Vitamin D plays an important role in enhancing the ability of monocytes and macrophages, two types of white blood cells, to fight pathogens. According to research published in the Journal of Investigative Medicine in 2016, vitamin D deficiency is associated with an increased risk of infection. Vitamin D also helps regulate the immune response, reducing the risk of infections such as colds and flu, especially in the winter when sunlight is reduced.
Vitamin E
Vitamin E is a powerful antioxidant that neutralizes free radicals and protects immune cells from oxidative damage. According to research published in the journal Vitamins & Hormones, vitamin E is important for the normal functioning of immune cells, supporting cell function and eliminating infected or abnormal cells.
Vitamin A
According to research published in Nutrition Clinique et Metabolisme, vitamin A also plays an important role in regulating the immune system. Vitamin A helps maintain the integrity of the skin and mucous membranes in the respiratory and gastrointestinal tracts, which are the body's first line of defense against infections. It also aids in the production of white blood cells and plays a role in regulating the immune response.
