What Is Vitamin C Deficiency?
Vitamin C (ascorbic acid) is a powerful antioxidant essential for immune function, collagen production, wound healing, and iron absorption. Since the human body cannot produce it, it must be obtained through diet.
Long-term deficiency may lead to scurvy, a rare but serious condition.
Causes of Vitamin C Deficiency
1️⃣ Poor and Unbalanced Nutrition
-
Low intake of fresh fruits and vegetables
-
Highly restrictive diets
-
Anorexia
-
Alcohol dependence
2️⃣ Smoking
Smoking increases oxidative stress and raises the body’s need for vitamin C. Smokers require higher daily intake.
3️⃣ Malabsorption and Chronic Diseases
Certain medical conditions may reduce vitamin C absorption, including:
-
Crohn’s disease
-
Ulcerative colitis
-
Diabetes (insulin resistance may reduce cellular uptake)
-
Liver failure
-
Dialysis treatment
Excessive antibiotic use and severe infections may also lower vitamin C levels.
