Which vitamin is essential for the formation of red blood cells?

• A. Vitamin A
• B. Vitamin B12
• C. Vitamin C
• D. Vitamin D

Answer: (B)

Vitamin B12 plays a crucial role in the formation of red blood cells. This vitamin is essential for DNA synthesis and is involved in the proper maturation of red blood cells in the bone marrow. A deficiency in vitamin B12 can lead to megaloblastic anemia, which is characterized by the production of oversized and dysfunctional red blood cells. This can result in insufficient oxygen delivery throughout the body, leading to various health issues. While other vitamins have their roles in overall health—such as vitamin A supporting vision and immune function, vitamin C contributing to collagen synthesis and acting as an antioxidant, and vitamin D being important for bone health and calcium absorption—they do not directly influence red blood cell production in the way that vitamin B12 does. Thus, B12 is specifically recognized for its critical function in maintaining healthy red blood cell levels.
