Vitamin C: Boosting Immune System and Reducing Cold Symptoms

While supplementing with vitamin C can alleviate symptoms, it does not prevent colds. However, vitamin C is essential for maintaining bone, muscle, and blood vessel health. It supports collagen formation, iron absorption, and strengthens the immune system by increasing the activity of T lymphocytes, phagocytic function, and leukocyte mobility. Additionally, vitamin C acts as an antioxidant, combating oxidative stress during infections.

Sufficient vitamin C in the body can increase resistance to disease and help reduce symptoms and shorten the duration of respiratory infections like colds, flu, bronchitis, and sinusitis. Food sources rich in vitamin C include guava, citrus fruits, bell peppers, kiwi, strawberries, papaya, broccoli
