What deficiency is associated with a lack of vitamin C?

Vitamin C deficiency is directly associated with scurvy, a condition characterized by symptoms such as bleeding gums, weakness, fatigue, and the appearance of spots on the skin due to the breakdown of collagen, which is vital for maintaining skin and connective tissue integrity. Scurvy occurs because vitamin C plays a critical role in collagen synthesis and antioxidant protection. Without an adequate intake of vitamin C, the body cannot perform these essential functions effectively, leading to the symptoms characteristic of scurvy.

Other conditions listed, such as anemia, pellagra, and beriberi, are associated with different nutrient deficiencies. Anemia can result from a deficiency in iron, vitamin B12, or folate. Pellagra is caused by a deficiency of niacin (vitamin B3), while beriberi is the result of a deficiency in thiamine (vitamin B1). Thus, these other deficiencies do not relate to a lack of vitamin C and instead indicate the importance of a varied diet for overall health.
