Vitamin A is mostly known for keeping your eyesight in tip-top form. However, it is also integral to the immune system. If you have moderate vitamin A deficiency, one of its symptoms is a reduced capability to combat illnesses specifically respiratory infections. Without this essential nutrient, our body will not be able to do most of its processes fully. Supplements can help you fill in the gaps in case you are not getting enough of the nutrient through dietary resources.
- What is the function of vitamin A in the immune system?
Answer: Vitamin A boosts the strength of the body’s innate and adaptive immune systems. Innate immunity shields the respiratory tract, gastrointestinal tract, eyes, reproductive organs and the skin. Adaptive immunity meanwhile generates antibodies which combat microorganisms which can cause infections, like the flu virus for example. A type of plant-based vitamin A, carotenoid, is a powerful antioxidant which helps prevent inflammation.
- What food sources are rich in vitamin A?
Answer: There are two kinds of vitamin A that you can get from food—retinoids, which are gathered from animal sources, and carotenoids, which come from plants. You can acquire retinoids from cow’s milk, eggs, beef liver, salmon, herring and shrimps. Vegetables like carrots, kale, spinach, mustard greens, collard greens, beet greens, turnip greens, winter squash and Swiss chard are rich sources of carotenoids.
- How much vitamin A is safe to take per day?
Answer: The recommended daily amount for vitamin A intake is 900mcg or adult men. The recommended dose for women is 700mcg. Vitamin A can be taken up to 3000mcg. Intake of more than 3000mcg can be toxic, leading to liver damage and swelling of the brain. Pregnant women who take more than 3000mcg of vitamin A is at high risk of acquiring fetal damage.
