Vitamin A helps support immune system health and regulate the healthy development of immune cells. Liver, sweet potatoes (with the skin), and carrots are great sources of vitamin A.
As we all know, vitamin A has a protective effect against infection. An important part of the protective roles might be through its ability to enhance antibody responses, especially IgA antibody responses in mucosal tissues.
How is vitamin A used in the body? Vitamin A is a powerful antioxidant. As it moves through your body it scavenges damaging free radicals and fights inflammation.
Vitamin A benefits are wide-reaching and also have an influential role in brain function, skin, heart, kidneys, lungs, vision, and immune system health. Its wide-reaching influences on your overall health have earned it the reputation of being an anti-aging vitamin.
Vitamin A is required for innate and adaptive immunity and is an immune enhancer that potentiates the antibody response, maintains, and restores the integrity and function of all mucosal surfaces. It is also essential for the very tissues that protect us from the same pathogens.
Vitamin A will dramatically improve your immune system health
The availability of vitamin A in our food is a key factor in a tolerant, highly functional immune system.
Vitamin A is crucial to a very sophisticated bi-directional mechanism that takes place in the digestive system. It leads to immune tolerance across the entire gut lining. Immune tolerance is the essence of good health. An intolerant immune system will lead to a wide range of illnesses. However, the gut is where many people first lose immune tolerance. So, Vitamin A is the key to our ability to consume a wide range of antigens (food) and yet not react adversely. And it’s quite fascinating.
The human body cannot synthesize Vitamin A; it must be absorbed by the intestine from the diet. In the presence of innate danger signals, Vitamin A effects can diminish or synergize with innate responses to promote or enhance protective immunity, ensuring suitable plasticity.
Vitamin A is an important and somewhat misunderstood nutrient. It’s critical to so many bodily functions and yet many of us don’t get enough of it. This is due to the combination of our dietary changes, the availability of our food sources, and our body’s fluctuating rates of conversion from the inactive to the active form. These factors have clouded the seemingly simple question – are you getting enough vitamin A to Strengthen Your Immune System Health?
