Vitamin C: Beyond Immunity
The multiple benefits of vitamin C from immunity to skin health.
Pharmacist's Note
Information below supports education and safer decision-making but does not replace one-on-one clinical advice.
Vitamin C is famous for fighting colds, but its everyday roles go much further. It is a powerful antioxidant that protects cells from damage, and it is essential for making collagen — the protein that keeps skin, gums, blood vessels, and joints strong. It also significantly improves the absorption of iron from plant foods.
Diet usually covers the basics
Citrus fruits, guavas, mangoes, tomatoes, and leafy greens are all rich local sources — a single guava can exceed your entire daily requirement. Because vitamin C is destroyed by prolonged cooking, lightly cooked or fresh produce delivers the most benefit.
When supplementation helps
Smokers need roughly 35 mg more vitamin C per day than non-smokers. People recovering from wounds or surgery, those with very limited diets, and anyone taking iron supplements for anaemia may also benefit from short-term supplementation. Regular vitamin C may slightly shorten colds, though starting it after symptoms begin shows weaker results.
Sensible limits
Doses above about 2000 mg daily commonly cause stomach upset and diarrhoea, and add little benefit — excess is simply passed in urine. People prone to kidney stones should keep doses moderate.
Combine any supplement plan with good nutrition and hydration, and ask the Sadima Pharmacy team which formulation — tablet, effervescent, or chewable — suits you best.
