At the start of the pandemic, various supplements were believed to decrease the severity–and or prevent the contraction of–COVID-19[FEMININECertainesdecesaffirmationsontensuiteétéréfutéespardesprofessionnelsdelasanté
Some of those that have been reaffirmed have been seen here and there via lists and academic journals but never codified.
Fortunately, a new study by the COVID Tracking Project attempts to do just that. The full article was published in medRxiv.
In addition to a recent analysis which concluded that sufficient amounts of vitamin D, vitamin C, zinc, and quercetin could dramatically improve the chances of beating COVID 19, the authors of the new report write the following:
“We looked for correlations between taking supplements and reporting positive tests for COVID-19 using PCR or serologic testing or having symptoms predictive of COVID. “
“We found that multivitamins, vitamin D, omega-3 and probiotic supplements all had a small protective effect against positive tests for the virus. In contrast, we didn’t see any protective effects for the other supplements we reviewed, like vitamin C, garlic, and zinc.
Interestingly enough, multivitamin, vitamin D, omega 3, and probiotic supplements appeared to produce beneficial effects for women in terms of transmission risk, but researchers did not observe the same consistent protective effect in women. samples from male patients.
“We observed a small but significant association between the use of probiotics, omega-3 fatty acids, multivitamins or vitamin D supplements and a lower risk of testing positive for SARS-CoV-2 in women. . No clear benefit for men has been observed nor any effect of vitamin C, garlic or zinc for men or women, ”the authors continued. “Randomized controlled trials of selected supplements would be needed to confirm these observational results before treatment recommendations can be made. “
It is not entirely shocking.
You may recall that men were disproportionately affected by critical symptoms of the coronavirus compared to women as early as January by public health officials. The reasoning was split between behavioral and biological factors.
According to the Centers for Disease Control and Prevention, 12% of women smoke cigarettes while 16% of men currently do and smokers are at greater risk of developing COVID-19-induced acute respiratory distress syndrome.
Men also make up the majority of statistics on cardiovascular disease, hypertension, and diabetes. Each condition is associated with serious manifestations of coronavirus infection.
In a recent meta-analysis of 1,099 COVID-19 patients and 543 SARS patients, the authors found that men have higher levels of the ACE2 protein that both diseases need to enter host cells.
None of this is to say that there are not broad conclusions that probably apply to all populations to one degree or another.
It should be noted that Dr Spector argues that people should prioritize public health measures rather than looking for cure-alls. This may be especially true for high-risk communities and, given the data from the study he contributed to, only supported modest effects.
“A lot of people think that taking vitamins and other supplements can help maintain a healthy immune system, but spending your money on supplements in the hope of trying to avoid contracting COVID-19 is largely unwarranted. You’d better focus on eating a healthy diet with a variety of fresh fruits and vegetables, which should give you all the nutrients you need for a healthy immune system, ”added Spector.
“Over the weekend, the government announced that it would provide 2.7 million vulnerable people in England with a free winter supply of vitamin D. Based on our research, we cannot say whether the supplements of vitamin D will have a real impact on these high risk groups. “
Putting the risk of COVID-19 aside for a moment, we know that the vitamins and supplements highlighted in the new medRvix report are extremely beneficial for overall health.
By putting the COVID-19 risk back into the picture, we see that each contributes doubly to important immune response functions.
Dr. Peter Osborne of the Origins Nutrition Center recently pleaded with Americans to have your blood tested for vitamin levels.
“I think that’s probably one of the smartest things a person can do right now, along with the unpredictable role of a relatively unknown disease. What we know at this point about vitamin therapy, especially vitamin D, a new study has come out and a new analysis has come out on what we know about vitamin D and COVID. So far, here’s what we know: People with low vitamin D who receive COVID have a greater tendency to die, have a greater tendency to hyper-inflammation in the cytokine storm that accompanies COVID, and have a greater tendency to use ventilators, which are very bad because ventilators do not work very well for COVID, ”wrote Dr. Osborne.
“When a person is on a ventilator with COVID, it is not a good thing. So the results aren’t great, so if we can stop people from using ventilators, and we can really support their immune systems through nutrition, that ideally makes the most sense. “
According to Osborne, nine in 10 COVID-19-related deaths could be prevented if people had adequate levels of vitamin D.
“Taking a multivitamin can improve the quality of daily life through increased energy, often with combinations of B vitamins, as well as other protective measures,” said Dr Danielle Plummer. , PharmD. “It’s important to choose a vitamin that contains the nutrients you are lacking and that meets your nutritional needs. “
