Jakarta, CNN Indonesia –
Drink vitamin C highly recommended to increase body immunity. So can vitamin C and zinc help you avoid Covid-19?
According to a randomized clinical study of two types of supplements, vitamin C and zinc (zinc) are not effective in reducing symptoms of Covid-19. This fact is inversely proportional to the popularity of these 2 supplements to fight covid-19 disease.
The research is published in JAMA Network Open on Friday (12/2). The study revealed that vitamin C and zinc did not benefit Covid-19 patients, even in high doses.
Unfortunately, the study was stopped early. These conclusions were drawn from a first-stage randomized clinical trial of samples under medical supervision.
In this clinical trial, covid-19 patients who were self-isolating were given high doses of vitamin C and zinc. The sample tested was three groups of Covid-19 patients consisting of 214 adults.
Meanwhile, the fourth group received standard care, such as rest, hydration, and fever-reducing drugs, but no vitamin C and zinc supplements, as a comparison.
“High doses of zinc gluconate (zinc), ascorbic acid (vitamin C), or both supplements do not reduce the symptoms of SARS-CoV-2 (corona virus),” said Milind Desai cardiologist from Cleveland Clinic. CNN.
Meanwhile, Professor of the Department of Medicine at the Johns Hopkins University School of Medicine Michos said high doses of vitamin C and zinc actually cause some unpleasant side effects for patients.
“More side effects, such as nausea, diarrhea, and stomach cramps, were reported in the supplement-given group than in the usual care group,” he wrote.
To improve immunity and body health, consumption of vitamin C and zinc according to the limits and doctor’s recommendations are still recommended.
As is well known, vitamin C is a popular supplement to prevent colds. Many Americans take vitamin C and zinc to fight the cold virus.
Vitamin C is a recognized antioxidant and plays an important role in supporting the immune system. Although it hasn’t been proven to prevent disease, other studies have found vitamin C can reduce colds by 8 percent in adults and 14 percent in children.
However, the National Institutes of Health says using vitamin C after cold symptoms start to appear doesn’t seem to help.
Meanwhile, Zinc can increase the ability of cells to fight infection. In addition, there is evidence that zinc deficiency can increase pro-inflammatory cytokines and decrease antibody production.
That means, if taken within 24 hours of the first signs of a cold, zinc can reduce the length of a cold by just one day. This conclusion is obtained from 13 studies.
However, the downside is consuming more than 2,000 milligrams of vitamin C a day can cause heartburn, stomach cramps, nausea, vomiting, diarrhea, and headaches. The average recommended daily intake of vitamin C is 75 milligrams for adult women and 90 milligrams for men.
Meanwhile, consuming more than 40 milligrams of zinc daily can cause dry mouth, nausea, loss of appetite, and diarrhea, coupled with an unpleasant metallic taste.
Currently, a number of scientists continue to explore the use of vitamins and other supplements in the treatment of COVID-19. Randomized trials are underway to see if vitamin D supplements can help patients recover.
Researchers in the US and China are using vitamin C by intravenous procedures or in the form of injections into a vein. The goal is to see if it can help people with severe enough respiratory failure.
Other studies are also still studying whether COVID-19 can be prevented with supplements such as vitamins C and D, and zinc.
However, based on preliminary research the use of vitamin C and zinc to accelerate the healing of COVID-19 patients does not appear to be useful.
