Vitamin A and Immunity

This refresher in the fat-soluble vitamin, vitamin A, is a precursor of posts later to come this week. Vitamin A is most known for its benefits for your eyes, but we will look at some of the other great things that it has to offer. Vitamin A can be found as a fat compound in the form of retinyl palmitate. This can be converted to 3 active forms: retinol, retinal, and retinoic acid. They’re responsible for:

  • cell attachment, growth and differentiation
  • maintains epithelial and mucosal tissue (in the lungs, trachea, skin, oral cavity, and GI tract), keeping these healthy is essential to providing a first  line of defense for the immune system
  • enhances function of white blood cells, increase response of antibodies to antigens, and have anti-viral activity
  • the retina stores 4 kinds of photopigments that store vitamin A (one responsible for night vision and the rest responsible for day-time vision)
  • essential for reproductive processes in both sexes

How do you get vitamin A? It is generally found in animal sources like calf liver, milk and eggs, although certain veggies and fruits can be converted to vitamin A (wait for more on this later in the week. Transportation and utilization is dependent on binding proteins (therefore a lack of protein in the diet can mean poor use of the vitamin A that you think you’re getting).
