[Vitamin C]

Area of Science:

• Nutrition Science
• Biochemistry

Context:

• Vitamin C (ascorbic acid) is an essential water-soluble nutrient.
• Dietary intake, primarily from fruits and vegetables, is crucial for maintaining adequate levels.
• Deficiency arises from insufficient daily consumption.

Purpose:

• To describe the clinical manifestations and diagnosis of Vitamin C deficiency.
• To outline the recommended treatment for scurvy.
• To highlight the importance of meeting the recommended dietary allowance for Vitamin C.

Summary:

• Scurvy, a condition resulting from Vitamin C deficiency, presents with fatigue, myalgia, arthralgia, purpura, and bleeding disorders.
• Biological markers include anemia, hypocholesterolemia, and hypoalbuminemia; diagnosis is confirmed by low ascorbic acid levels (< 2 mg/L), interpreted alongside acute phase reactants.
• Treatment involves daily 1g Vitamin C administration for 15 days, with depletion potentially leading to long-term complications.

Impact:

• Ensuring adequate Vitamin C intake through recommended dietary allowances is vital for preventing scurvy and associated health complications.
• Early diagnosis and treatment of Vitamin C deficiency are essential for patient recovery and well-being.
• Understanding the biochemical and clinical aspects of Vitamin C deficiency aids in public health nutritional guidance.
