                                Vitamin A is a fat-soluble vitamin essential for vision, immune function, and reproduction. However, when asking, "is vitamin A an acid?," the answer is complex because the term refers to a group of compounds called retinoids, which include alcoholic, aldehydic, and acidic forms. The most potent, biologically active form in the body is retinoic acid, but the primary dietary forms are not acidic.
