Vitamin C has been used as a treatment for the various viruses that cause the common cold for decades. Conventional medicine states that there is no bona fide evidence that vitamin C works. They based this on “randomized clinical trials.” There have been very few randomized trials on vitamin C due to the exorbitant cost of these trial, reaching $5b. Only synthetic substances are run through such trials because they are covered by patent law. Natural substances, like vitamin C are NOT patentable. However, because of the long history of vitamin C, there have been a few randomized trials and over 1,000,000 other studies on vitamin C, with many of those showing benefit in people with infectious respiratory diseases. Vitamin C does not prevent viral infections. Vitamin C does, however, significantly reduce the severity of symptoms. At NY hospitals, intensive-care patients with the coronavirus immediately receive 1,500 milligrams of intravenous vitamin C. The patients who received vitamin C did significantly better than those who did not get vitamin C. According to one doctor, “It helps a tremendous amount, but it is not highlighted because it’s not a sexy drug.”
