How Vitamin A Supports the Immune System
Vitamin A supports immune function by promoting the production of white blood cells that help fight off infections. It also helps maintain the integrity of the skin and mucous membranes, which serve as barriers to pathogens. Vitamin A also has antioxidant properties that protect cells from damage caused by free radicals.
Sources of Vitamin A
- Carrots
- Sweet potatoes
- Spinach
- Kale
- Butternut squash
- Liver (beef or chicken)
Recommended Dosage
Women should aim for 700 micrograms (mcg) of vitamin A daily. It is important to note that excessive intake of vitamin A, especially from supplements, can be harmful. Always aim for a balanced diet rather than relying on high doses of supplements.
4. Vitamin E
Vitamin E is a powerful antioxidant that helps protect cells from oxidative damage. It also plays a significant role in maintaining immune function by supporting the activity of immune cells.
How Vitamin E Supports the Immune System
Vitamin E helps to enhance the production of immune cells, including T-cells and B-cells, which are responsible for fighting off infections. It also plays a role in the regulation of inflammatory responses, helping to prevent chronic inflammation that can weaken the immune system. Additionally, vitamin E has been shown to improve the body’s ability to respond to vaccines and other immune challenges.
Sources of Vitamin E
- Almonds
- Sunflower seeds
- Spinach

The recommended daily intake of vitamin E for women is 15 milligrams (22.4 IU). Most women can get enough vitamin E through a balanced diet, but supplements may be necessary in some cases.
5. Vitamin B6
Vitamin B6, also known as pyridoxine, plays an important role in supporting the immune system. It is involved in the production of red blood cells and the metabolism of proteins, both of which are essential for maintaining good health.
How Vitamin B6 Supports the Immune System
Vitamin B6 is essential for the production of neurotransmitters and immune cells, including those that help fight infections. It also helps regulate the production of cytokines, proteins that help the immune system respond to inflammation. Adequate levels of vitamin B6 can improve the body’s response to infections and reduce the risk of chronic diseases.
Sources of Vitamin B6
- Chicken
- Turkey
- Fish (salmon, tuna)
- Potatoes
- Bananas
- Chickpeas
Recommended Dosage
Women should aim for 1.3 to 2.0 milligrams of vitamin B6 daily. Pregnant or breastfeeding women may require slightly higher amounts. As with other vitamins, it is important to focus on obtaining vitamin B6 through whole foods, as excessive supplementation can have negative effects.
6. Folate (Vitamin B9)
Folate, or vitamin B9, is essential for cell division and the production of DNA. It is particularly important during pregnancy, as it helps prevent birth defects and supports the development of the fetus. Folate also plays a role in maintaining a healthy immune system.
How Folate Supports the Immune System
Folate helps support immune function by promoting the production of red blood cells and maintaining healthy cell division. Adequate folate levels are linked to improved immune responses and a reduced risk of certain infections. Folate also helps the body break down homocysteine, an amino acid that, when elevated, can increase the risk of cardiovascular disease.
Sources of Folate
