A cheap OTC treatment that has mixed results in clinical studies, but I use it personally when I have an upper respiratory illness. Vitamin C can play a supportive role in managing upper respiratory illnesses by reducing symptom duration and severity, particularly in high-risk groups. However, it is not a guaranteed preventive measure for URIs in the general population. Regular intake of Vitamin C through a balanced diet or moderate supplementation is advisable for overall immune health, with higher doses potentially beneficial during illness.
