The Centers for Disease Control and Prevention defines flu as any contagious respiratory condition caused by influenza viruses. The symptoms can range from mild to severe, and sometimes, it can lead to death. Flu is different from a common cold. Flu symptoms include fever, cough, sore throat, runny nose, and extreme fatigue. Flu and cold symptoms often share the same manifestations except for fever and chills. Flu symptoms are also stronger and may develop suddenly.
The best way to protect yourself from flu is by getting a yearly vaccination, says the Centers for Disease Control and Prevention. However, not everyone chooses to get vaccinated. Many people nowadays would choose to explore natural ways of immune-strengthening to protect themselves from influenza.
The Role of Vitamin C in the Body
Vitamin C is a potent antioxidant that plays a role in the immune boost. The Vitamin C level in the body is depleted during infection or rhinovirus, making the person more susceptible to respiratory tract infection. In a severe state of infection, Vitamin C in intravenous may be needed for quick replacement of the micronutrient. Vitamin C protects the body by microbial killing and preventing the host’s tissues from excessive damage. It has a role in immune cell function that manages and treats respiratory infections.
Why are You Missing Vitamin C?
Vitamin C is the fourth leading food deficiency in the United States. Inadequate intake of vitamin-rich food sources is the leading cause. Smoking, pollution, and the presence of environmental oxidative stresses are other factors of lack of the vitamin. Vitamin C can be obtained by eating vitamin-rich foods, oral supplementation, and intravenous therapy for susceptible groups like elderly and sick people.
The daily serving of Vitamin C is 200 mg or that is, equivalent to 5 to 9 food servings. Fruits and vegetables such as mango, kiwi, tomatoes, peppers, broccoli, and citrus fruits are excellent fruit sources. Try to go for fresh fruits and vegetables and skip the frozen and processed foods. On the other hand, in cold regions where vegetation is sparse, locals resort to alternative sources of Vitamin C such as herbal teas and animal organs.
Vitamin C and Intravenous Therapy Definition
Intravenous therapy is the administration of vitamin fluid through a vein. It is the fastest way to replace fluid loss and deliver nutrients. A high dosage of Vitamin C has been clinically tested and evaluated in improving flu symptoms and preventing serious complications of flu such as pneumonia. It also promotes immune defense by stimulating cellular functions of the immune system.
In a clinical study in the United States, patients with sepsis-related ARDS have shown signs of improvement following intravenous therapy procedure of 15 g of Vitamin C daily. It was also discovered that doctors in Wuhan, China have used such intravenous therapy for immune strengthening in patients who have developed pneumonia due to COVID-19.
Overall, Vitamin C is involved in many body functions particularly in immune boost and fighting infection. It is easily available in food sources, supplements, and intravenous therapy. A daily intake of at least 200 mg of Vitamin C is adequate to optimize daily cellular functions. However, people in susceptible groups or have an infection may need a higher dose of Vitamin C intravenously to compensate for the increased metabolic demand of the body.
