By neutralizing them, Vitamin C helps protect immune cells from potential harm, thereby supporting immune function.
- Shortens Illness Duration: When taken regularly and in recommended doses, Vitamin C can reduce the duration and severity of cold and flu symptoms. It may not prevent you from catching a virus, but it can aid in faster recovery and alleviate discomfort during illness.
To ensure you’re receiving adequate Vitamin C, incorporate foods rich in this nutrient into your diet. Citrus fruits, berries, kiwi, bell peppers, and leafy greens are excellent sources. If you struggle to meet your daily requirements through diet alone, consider taking Vitamin C supplements after consulting with a healthcare professional.
Remember, while Vitamin C is a valuable tool in boosting your immune system, it should be complemented with a well-balanced diet, regular exercise, sufficient sleep, and good hygiene practices to maintain optimal overall health.
The Role of Vitamin C in Fighting Respiratory Infections
