COVID-19 | SUPPLEMENT OF VITAMIN C - INCREASE RESISTANCE AGAINST COVID-19

1, Doctor, Why is Vitamin C an important nutrient to help increase resistance to prevent Covid-19? Supplementing with Vitamin C is necessary to protect health, increase metabolism and strengthen the resistance barrier, thereby supporting the enhancement of the immune system. According to the study "Vitamin C and Resistance Function" published in the US National Library of Medicine: "Vitamin C contributes to immune defense by supporting various cellular functions of both the innate and adaptive fluids immune system. Vitamin C accumulates in phagocytic cells, such as neutrophils, which produce reactive oxygen species, and ultimately destroy microorganisms." This study also shows that: "Vitamin C deficiency leads to impaired immunity and increased susceptibility to infections. Furthermore, vitamin C supplementation can prevent and treat respiratory and systemic infections Dear". High-dose intravenous vitamin C supplementation can help improve lung function, help reduce morbidity, and limit the risk of requiring mechanical ventilation. 2, What evidence shows that Vitamin C effectively increases resistance for people infected with Covid-19? SARS-CoV-2 is a new virus that has been around since 2019. Several studies of infections across a variety of conditions have shown vitamin C to be beneficial in certain groups of people, especially patients with Covid-19 . Currently, there are at least two trials underway specifically using vitamin C to treat two coronavirus patients with severe symptoms, one in New York and one in China. To date, the effects of vitamin C supplementation have been reported, including: Elderly people with acute respiratory infections Acute respiratory distress syndrome Reduce the severity and duration of the common cold Reducing length of hospital stay and symptoms in elderly patients with pneumonia Reduce mechanical ventilation time of patients treated in ICU (intensive resuscitation) 3, So doctor, how much vitamin C is enough? According to research by nutritionists, the maximum limit of vitamin C that the body can accept is 2,000mg of vitamin C for people over 19 years old. The same applies to pregnant and lactating women.

As a result, the required intake of vitamin C will increase to cope with this deficiency. There are also limited doses of vitamin C for specific exceptions. However, the exception limit dose is usually applied only with the consent of medical professionals. 4, If taking too much vitamin C, will it cause any harm to the body, doctor? When a person takes more than the limit of vitamin C that the body needs, symptoms such as digestive disorders, stomach ulcers, cystitis, diarrhea, increased kidney stone formation, gout, and decreased blood sugar levels will occur. requirements, interfere with the absorption of vitamins A and B12. Do not arbitrarily supplement vitamin C by mouth, especially high-dose vitamin C without a doctor's prescription. Taking too much vitamin C by mouth can cause side effects. In particular, pregnant women taking high doses of vitamin C for a long time may cause an abnormal demand in the fetus. 5, So doctor, can you tell which foods are rich in vitamin C?
