Vitamin C is a vital nutrient that plays several roles in maintaining overall health and well-being. In this article, we will explore the significance of vitamin C, the consequences of its deficiency, and highlight some fruits and vegetables that can help you meet your daily requirements.
The Role of Vitamin C in Your Body
Vitamin C is essential for numerous functions in the body, including:
Collagen Synthesis: Vitamin C is essential for synthesising collagen, a protein that supports connective tissues like skin, cartilage, and blood vessels, aiding in wound healing and skin integrity.
Antioxidant Activity: As a powerful antioxidant, vitamin C neutralizes free radicals, potentially reducing the risk of chronic diseases such as cancer and cardiovascular issues.
Immune Function: Vitamin C boosts immune cell function and strengthens the skin's barrier against pathogens, helping to lessen the duration and severity of colds.
Iron Absorption: It enhances the absorption of nonheme iron, which is vital for preventing iron deficiency anaemia.
Vitamin C Deficiency
The deficiency of vitamin C, also known as scurvy when severe, results from less intake of this essential nutrient.
Symptoms of Vitamin C Deficiency
The symptoms can vary from mild to severe, including:
- Early Signs: Fatigue, irritability, and joint pain.
- Progressive Symptoms: Bleeding gums, easy bruising, poor wound healing, and corkscrew hairs.
If left untreated, severe deficiency can lead to scurvy, characterised by significant bleeding under the skin and swollen gums.
Recommended Daily Intake of Vitamin C
The recommended dietary allowance (RDA) for vitamin C varies by age and gender:
Adults:
Men: 90 mg per day
Women: 75 mg per day
Pregnant women: 85 mg per day
Breastfeeding women: 120 mg per day
Children:
Ages 1-3: 15 mg per day
Ages 4-8: 25 mg per day
Ages 9-13: 45 mg per day
Ages 14-18: Boys: 75 mg per day
In cases of deficiency or increased need, higher doses may be recommended. Adults can safely consume between 500 mg to 1000 mg daily.
