What is a major consequence of vitamin C deficiency?

Vitamin C deficiency primarily leads to scurvy, which is characterized by symptoms such as fatigue, swollen gums, joint pain, and anemia caused by the impaired synthesis of collagen. Collagen is crucial for maintaining the structure of connective tissues, and its deficiency due to a lack of vitamin C affects the integrity of blood vessels, skin, and bones.

Scurvy occurs because vitamin C, or ascorbic acid, is an essential nutrient that supports various bodily functions, including the biosynthesis of collagen, neurotransmitters, and the metabolism of certain amino acids. Without adequate vitamin C, the body cannot properly form collagen, which results in the symptoms associated with scurvy.

The other options represent conditions related to different nutrient deficiencies or health issues. Rickets is caused by a deficiency in vitamin D, calcium, or phosphate, leading to weak or soft bones. Anemia can be a result of several conditions, including iron deficiency or vitamin B12 deficiency, rather than a direct consequence of low vitamin C. Osteoporosis, characterized by weak and brittle bones, is often connected to calcium and vitamin D deficiencies or hormonal changes rather than vitamin C levels. Therefore, scurvy is the major consequence of vitamin C deficiency.
