By this point, several published research papers and clinical trials have shown that vitamins D and C, as well as minerals such as zinc and magnesium, may reduce the severity of symptoms in COVID-19 patients. However, one researcher is now calling on scientists to explore another helpful vitamin that may have been overlooked.  In an opinion article published in the journal Frontiers in Nutrition Thanutchaporn Kumrungsee, an assistant professor at Hiroshima University in Japan, proposed that vitamin B6 could play a pivotal role in fighting the novel coronavirus. (Related: The One Vitamin Doctors Are Urging Everyone to Take Right Now.)  “There is growing evidence that vitamin B6 exerts a protective effect against chronic diseases such as cardiovascular diseases (CVD) and diabetes by suppressing inflammation, inflammasomes, oxidative stress, and carbonyl stress,” the article reads. “Additionally, vitamin B6 deficiency is associated with lower immune function and higher susceptibility to viral infection.”  However, some health experts remain suspicious—and for good reason. Ali Webster, PhD, RD, and Director of Research and Nutrition Communications at the International Food Information Council says it’s still too soon to determine whether or not the vitamin could help to lower the risk of experiencing adverse COVID-19 symptoms.  “There are plausible biological mechanisms for it doing so, and low levels of B6 in the body are associated with a weakened immune system. But often, the promise of a positive impact is there but the outcome of well-designed studies is disappointing,” she says.  Webster explains the research on taking vitamin B6 in supplement form to reduce the risk for heart disease, stroke, certain types of cancer, and even cognitive decline is a bit inconclusive, as well.  “More research is needed in each of these areas, in addition to the work to determine its effect on COVID-19 severity,” she adds.  Brittany Busse, MD, Associate Medical Director at WorkCare agrees that more research is needed, however, notes that vitamin B6 is known to have an anti-inflammatory effect on the body, which could help you in both preventing and combating adverse COVID-19 symptoms.  “There are a lot of vitamins that can help decrease inflammation, potentially, and B6 is one of them,” she says.  She also adds that the severity of COVID-19 is based largely on how much inflammation your body creates in response to the virus. This is why it’s key to keep inflammation levels low by eating a diet that’s rich in fruits, vegetables, and legumes; engaging in regular, moderate exercise; getting plenty of sleep, and managing stress.  “In a good, normal state of health, we would want to have as little inflammation in our bodies as possible before becoming infected with COVID,” says Busse. “Then, we do what we can, once you become sick, to try and reduce your body’s over-reactiveness to the virus.”  Similar to vitamins D and K, Busse says vitamin B6 may operate as an an
