Vitamin A plays several important roles in the body.
First, it is essential for vision. Vitamin A helps maintain the health of the retina, which is the part of the eye that converts light into signals that are sent to the brain.
Second, Vitamin A is important for the immune system. It helps regulate the growth and differentiation of cells, including those that are involved in the immune response.
Third, Vitamin A is necessary for the growth and development of cells and tissues in the body, including those in the skin, bones, and reproductive system.
Finally, Vitamin A is an antioxidant, which means it helps protect cells from damage caused by harmful molecules known as free radicals.
Sources of Vitamin A include animal products, such as liver, eggs, and dairy, as well as some plant-based sources, such as sweet potatoes, carrots, and spinach. It is also available in supplement form, but it is important to talk to a healthcare provider before taking any supplements, as high doses of Vitamin A can be toxic.
