From Vision to Immunity: Understanding Vitamin A's Role

Vitamin A is a vital nutrient that plays a crucial role in maintaining good vision, supporting the immune system, and promoting overall health. Vitamin A deficiency poses serious health risks, including night blindness and severe vision impairment. This deficiency is a leading cause of childhood blindness and can contribute to maternal mortality, weakened immune systems, growth issues, and increased vulnerability to infections.
