Which vitamin is recommended to treat a patient presented with scurvy?

Scurvy is a condition caused by a deficiency of vitamin C, which plays a crucial role in the synthesis of collagen, a protein that helps maintain the structure and function of connective tissues. Vitamin C is also essential for the metabolism of certain amino acids and for the absorption of iron from plant-based foods. When a person does not consume enough vitamin C, they may experience symptoms such as fatigue, swelling, and bleeding gums, which are characteristic of scurvy.

Therefore, the recommended treatment for a patient with scurvy is to increase vitamin C intake, either through dietary sources like citrus fruits, berries, and leafy greens, or through supplementation. This will help restore adequate levels of vitamin C in the body, thereby alleviating the symptoms associated with the deficiency.

Other vitamin options like D, B12, and A play important roles in various metabolic processes, but they do not address the specific needs of a person suffering from scurvy, making vitamin C the most appropriate choice for treatment.
