                                While severe vitamin B3 deficiency (pellagra) is rare in industrialized countries, it remains a significant health concern in food-limited populations globally. A lack of this essential nutrient can profoundly impact the skin, digestive system, and nervous system, leading to a range of noticeable and progressive symptoms.
