Which condition results from a deficiency of vitamin C?

Scurvy is a condition that arises from a deficiency of vitamin C, also known as ascorbic acid. Vitamin C plays a vital role in the synthesis of collagen, which is an essential protein that helps maintain the integrity of connective tissues, skin, and blood vessels. Without adequate vitamin C intake, the body struggles to produce sufficient collagen, leading to symptoms associated with scurvy such as fatigue, gum disease, joint pain, and easy bruising. This condition highlights the importance of vitamin C, commonly found in fruits and vegetables, particularly citrus fruits, in maintaining health and preventing disease.

Other conditions listed are linked to different nutrient deficiencies. Rickets is caused by a deficiency of vitamin D, calcium, or phosphate; anemia can result from various nutritional deficiencies, most commonly iron; and pellagra is associated with a deficiency of niacin (vitamin B3). Understanding the specific nutrients involved in these conditions helps clarify why scurvy is directly connected to a lack of vitamin C.
