The Power of Vitamin C: Health Benefits, Sources, and Daily Requirements
What is Vitamin C or Ascorbic Acid?
Vitamin C, or ascorbic acid, is a water-soluble vitamin that our body cannot store for future use. It is excreted through urine, which makes daily intake of vitamin C crucial.

- Enhances collagen production for healthy hair, skin, muscles, and tissues.
- Aids in iron absorption, preventing iron deficiency.
- Boosts immunity by increasing white blood cell production.
- Improves semen quality by enhancing sperm motility and count.
Top Food Sources of Vitamin C
- Citrus fruits (oranges, lemons)
- Broccoli, cauliflower, and cabbage
- Kiwi, papaya, mango, guava

Definition of Scurvy
Scurvy is a medical condition that develops when the body doesn’t get enough Vitamin C over an extended period. This essential nutrient, also known as ascorbic acid, is crucial for the production of collagen- a protein that helps maintain healthy skin, blood vessels, bones, and connective tissue.
Without adequate Vitamin C, the body’s ability to repair tissue and heal wounds is impaired, leading to symptoms such as fatigue, bleeding gums, loose teeth, bruising, joint pain, and in severe cases, anemia and delayed wound healing.
Scurvy is relatively rare today but still occurs, particularly among individuals with poor nutritional habits. It is most commonly seen in elderly adults, especially those living alone, in long-term care facilities, or with limited access to fresh fruits and vegetables. People with alcohol dependency, eating disorders, or certain mental health conditions that affect diet are also at increased risk.
The condition is easily preventable and treatable with proper dietary intake of Vitamin C. Just a daily dose from fruits like oranges, kiwis, strawberries, or vegetables like bell peppers and broccoli can be enough to maintain healthy levels and prevent scurvy.
Skin Benefits of Vitamin C
Increases collagen production to maintain skin elasticity, reducing fine lines and wrinkles.
Helps retain moisture, leading to soft and glowing skin.
Restores skin’s natural glow by protecting against pollutants and UV rays.
Regulates melanin production for a more even skin tone.
Acts as an antioxidant, neutralizing harmful toxins produced during digestion or due to pollution and smoking.
Hair Benefits of Vitamin C
1. Treats Damaged Hair
Neutralizes free radicals, improving hair texture and strength.
2. Fights Dandruff
Removes toxins from the scalp, preventing dandruff and infections.
3. Supports Hair Growth
Boosts collagen and improves scalp circulation, promoting stronger hair.

Conclusion
Vitamin C, also known as ascorbic acid, is far more than just an immune booster- it is an essential micronutrient that plays a foundational role in maintaining overall health and well-being. From supporting the immune system and enhancing iron absorption to promoting collagen synthesis and serving as a powerful antioxidant, Vitamin C influences a wide range of biological functions critical to daily vitality and long-term disease prevention.
Its protective effects against oxidative stress, cardiovascular disease, certain cancers, and skin aging make it a cornerstone of preventative health strategies in both clinical nutrition and integrative medicine. Furthermore, its involvement in wound healing, brain health, and immune modulation underlines its value across various age groups and health conditions.
Incorporating Vitamin C into your daily diet is both simple and effective. Rich natural sources include citrus fruits, berries, kiwis, bell peppers, leafy greens, and tomatoes, while high-quality supplements can serve as a reliable alternative when dietary intake falls short. Adhering to recommended daily intake levels- typically 75 mg for women and 90 mg for men, with higher needs for smokers and those under physical stress- ensures optimal physiological function and protection.
As research continues to uncover the multifaceted benefits of Vitamin C, one thing remains clear: consistent intake of this vital nutrient can contribute significantly to enhanced immunity, reduced inflammation, improved skin health, and a lower risk of chronic diseases. Whether through food or supplementation, prioritizing Vitamin C is a simple yet powerful step toward a healthier life.
