Vitamin C, especially at higher than RDA doses, provides numerous benefits due to its antioxidant and anti-inflammatory properties, including reducing chronic diseases like heart disease; lowering blood pressure by improving integrity of blood vessels; and boosting iron absorption. High-dose vitamin C has been shown to improve memory by increasing blood flow and reduce severity and duration of viral diseases, including the common cold., intravenously, at high doses is now proven to slow the progression of COVID-19 \ ˈkō-vid-nīn-ˈtēn : a mild to severe respiratory illness that is caused by a coronavirus (Severe acute respiratory syndrome coronavirus 2 of the genus Betacoronavirus), is transmitted chiefly by contact with infectious material (such as respiratory droplets), and is characterized especially by fever, cough, and shortness of breath and may progress to pneumonia and respiratory failure. and, in many cases, reduce symptoms dramatically and probably reduce mortality. This will continue to be a controversial subject. However, the evidence in favor of high dose vitamin C is overwhelming. In the national library of medicine, there are 948,000 publications associating vitamin C usage to respiratory condition, many of which demonstrate improved outcomes. Harvard Medical School and the Harvard School of Public health publish information of high dose IV vitamin C and show research studies that more than suggest its effectiveness against COVID-19. Some brave doctors on the frontline of COVID-19 in New York are using high dose IV on hospitalized patients because they know it provides benefits. Ask anyone who speaks against high dose vitamin C if they want take it if diagnosed and hospitalized with COVID-19. Their use of vitamin C may imply a shortage or available, but unproven pharmaceutical, or the belief that vitamin C is at least as effective without severe side effect potential.
