                                Globally, millions of people suffer from vitamin A deficiency, which is known to cause severe health issues, including preventable blindness. The primary reason for this devastation is that a lack of vitamin A disrupts cell differentiation, causing keratinization of epithelial cells in delicate tissues where it does not belong.
