Vitamin C: More Than Just Immunity
Vitamin C (ascorbic acid) is a water-soluble vitamin and a powerful antioxidant involved in hundreds of biological processes. The body cannot produce it itself — we must obtain it daily from food or supplements. And although it is best known for its role in immunity, its true scope is much wider.
Vitamin C deficiency is more common than thought — especially in people with an unbalanced diet, smokers, people under chronic stress, and those with intense physical activity. Symptoms include fatigue, frequent infections, slow wound healing, and impaired skin quality.
What does vitamin C do in the body?
1. Immune Defense
Vitamin C stimulates the production and function of white blood cells — especially neutrophils and lymphocytes. It is concentrated in immune cells and is rapidly depleted during infection. Regular intake keeps the immune response ready and active.
2. Collagen Synthesis
Vitamin C is an indispensable cofactor for collagen synthesis — the main structural protein of skin, joints, bones, and blood vessels. Without sufficient vitamin C, collagen cannot form properly, leading to slower healing and impaired skin elasticity.
3. Powerful Antioxidant
Vitamin C neutralizes free radicals — unstable molecules that damage cells and accelerate aging. It also regenerates vitamin E, enhancing the body's antioxidant defense.
4. Iron Absorption
Vitamin C significantly improves the absorption of non-heme iron (from plant sources). Taking it with iron-rich foods or supplements can increase absorption by up to 67%.
5. Energy and Reduction of Fatigue
Vitamin C is involved in the synthesis of carnitine — the molecule that transports fatty acids into mitochondria for energy production. Adequate levels support normal energy metabolism and reduce feelings of fatigue.
Buffered Form vs. Standard Ascorbic Acid
Standard ascorbic acid is effective, but at higher doses, it can irritate the stomach. Buffered vitamin C (such as calcium ascorbate) is neutralized with a mineral, making it significantly gentler on the stomach lining — without compromising effectiveness.
- ✅ Suitable for sensitive stomachs
- ✅ Better tolerance at higher doses
- ✅ Provides an additional mineral (calcium or magnesium)
- ✅ Same antioxidant and immune activity
What dosage is appropriate?
- Recommended daily allowance: 80 mg (NRV for EU)
- For immune support: 500–1,000 mg daily
- For stress or intense physical activity: up to 2,000 mg daily
- Smokers: needs are ~35% higher
- Take with food for better tolerance
- Vitamin C is water-soluble — excess is excreted in the urine
