Vitamin C is essential for the prevention of scurvy because it plays a crucial role in collagen synthesis, which is necessary for the health of connective tissues, skin, and blood vessels. Without sufficient Vitamin C, the body cannot properly form collagen, leading to symptoms associated with scurvy, such as fatigue, joint pain, and bleeding gums. This vitamin also acts as an antioxidant, helping to protect cells from damage. The historical context of scurvy, particularly among sailors who lacked fresh fruits and vegetables, highlights the critical need for Vitamin C in the diet. In contrast, Vitamin A, B12, and D have different roles in the body, and deficiencies in those vitamins lead to other health issues rather than scurvy.
