Melissa Majumdar, RD, LDN, a nurse and spokesperson for the Academy of Nutrition and Dietetics, said that any product saying it can prevent or cure coronavirus is violating federal standards.
“There is no supplement or herb that can prevent or cure coronavirus,” Majumdar said.
“Vitamins A, D, C, zinc, and iron are most known for their roles in the immune system,” she said. Instead of taking additional supplements, focus on other aspects of supporting your immune system such as exercising, hydrating, getting enough sleep, and getting enough fruits and vegetables.
“Everybody’s desperate,” Jon C. Tilburt, MD, a physician at Mayo Clinic, told Healthline. “It is understandable that patients want to do whatever they can to prevent getting or spreading the virus.” There are several relatively safe supplements such as zinc that “may be safe to try,” Tilburt concurred. None are proven, and they are not a substitute for public health measures, he said.
“Nasal zinc sprays can cause loss of smell. That can be permanent,” noted Beth Kitchin, PhD, a registered dietitian, nutritionist, and assistant professor at the University of Alabama at Birmingham.
Frank Romanelli, PharmD, a professor at the University of Kentucky, said some reports have said zinc can have some antiviral effects, and that vitamin C may help with the respiratory syndrome associated with severe COVID-19 infection, but this is all anecdotal.
As for people loading up on “safe” vitamins and minerals, experts say they shouldn’t do it.
“Megadoses of vitamins can be dangerous. And they aren’t going to prevent or treat COVID or even shorten the duration of the disease,” Kitchin said.
If someone is truly deficient in a nutrient, getting themselves up to a healthy level may help support the immune system.
“But the idea that more is better is not only wrong, it can be dangerous,” Kitchin added.
“There is no supplement or herb that can prevent or cure coronavirus,” Majumdar said.
That maybe so, but it it can reduce the time you suffer from this virus greatly and to be effective it should be in your system BEFORE you contract the virus as it also will help your immune system to fight off this virus. And the combination of these nutrients-vitamins as suggest by an MD is QUERCETIN-ZINC-C-D-MELANTONINE-B-COMPLEX. This combination is not only beneficial for fighting off this virus but also beneficial to your overall health.
Also there is one substance widely used commercially wherever large groups of animals are raised to keep viruses down and this same substance by the name of BHT will do the same for humans, if and when used properly. Here, it may be of interest to note that a patent had been filed with the number US4350707 for BHT because of its LIPID COVERED virus killing ability approximately 30 years ago, however in the meantime this patent has expired.
I have seen both approaches work. With BHT being effective against herpes as well as shingles and the Covid-19 virus. Of course as with herpes, once you have it you only can keep it in remission and that’s what BHT does in most cases. Again, I have seen it work with my own eyes and it would be difficult to convince me otherwise. Needless to say if you fail and wait around to address this virus until it may also turn into a bacterial infection then you really will need a more heavy duty approach.
