How Do Vitamins Support Overall Immune Function?
Vitamins are critical for the proper functioning of the immune system:
1. Vitamin C
Vitamin C enhances the production and function of white blood cells, which are essential for fighting infections. It also acts as an antioxidant, protecting immune cells from damage. A review in Nutrients (2018) confirmed that vitamin C supplementation boosts immune function and helps prevent and treat respiratory infections.
2. Vitamin D
Vitamin D modulates the immune response, helping to reduce inflammation and enhance the body's ability to fight off pathogens. It plays a key role in both the innate and adaptive immune systems. Research in The Journal of Clinical Endocrinology & Metabolism (2020) found that adequate vitamin D levels are associated with a lower risk of infections and autoimmune diseases.
3. Vitamin A
Vitamin A supports the health of the skin and mucous membranes, which are the body's first line of defense against pathogens. It also plays a role in the development and function of white blood cells. A study in The American Journal of Clinical Nutrition (2019) highlighted the role of vitamin A in maintaining immune health and reducing the risk of infections.
