Who would have thought vitamin B6 which is commonly found in the bananas and oatmeal you might regularly eat may be key to your body’s fast response against COVID-19?
Although vaccines are now available for COVID-19, many people are struggling to get an appointment. Health officials are telling the public the demand is far greater than the supply and to be patient.
Luckily, research has explored the benefits of vitamins D and C and minerals like zinc and magnesium in fortifying the immune system against COVID-19. And many experts agree that dietary supplements can help in the fight against the viurs. But scientific research on the critical role of vitamin B6 has been missing.
Vitamin B6 is found in many foods, however, if you are deficient in other B complex vitamins such as folate and B12, you are more likely to be deficient in B6 as well.
COVID-19 is a good reason to beef it up…
Vitamin B6 may prevent severe infection from COVID-19
Vitamin B6 plays a pivotal role in cell functioning, energy metabolism, and acts as an anti-inflammatory agent. A diet rich in B6 exerts a protective effect against a host of chronic illnesses such as cardiovascular diseases, diabetes, rheumatoid arthritis, including chronic inflammatory bowel disease.
Now, food scientist Thanutchaporn Kumrungsee has published a paper in Frontiers in Nutrition citing growing evidence of the vitamin’s potential in lowering the odds of becoming seriously ill with the coronavirus.
“In addition to washing your hands, food and nutrition are among the first lines of defense against COVID-19 virus infection. Food is our first medicine and the kitchen is our first pharmacy,” Kumrungsee, an associate professor at Hiroshima University’s Graduate School of Integrated Sciences for Life, said.
Vitamin B6 is a known anti-thrombosis and anti-inflammation nutrient and Kumrungsee believes it may help dampen the cytokine storm phenomenon (hyper inflammation), including blood clotting, that’s been linked to COVID-19’s lethality. Severe COVID-19 infections have resulted in blocked capillaries which damage major organs like the heart, lungs, liver and kidneys.
“Vitamin B6 has a close relationship with the immune system. Its levels always drop in people under chronic inflammation such as obesity, diabetes, and heart diseases. We can see from the news that obese and diabetic people are at high risk for COVID-19,” Kumrungsee said.
“Thus, our attempt in this paper is to shed light on the possible involvement of vitamin B6 in decreasing the severity of COVID-19.”
The associate professor is looking forward to clinical trials to test whether B6 exerts protection against novel types of virus infection and pneumonia — and hopes that after COVID-19, research into nutrition for lung disease, including cancer, will continue.
Signs and symptoms of a B6 deficiency
Though we don’t have definitive evidence yet of B6’s efficacy in dousing the effects of COVID-19, deficiency of the vitamin is associated with lower immune function and higher susceptibility to viral infections. So, it makes sense to make sure you’re not deficient.
Signs of deficiency include:
- Skin rashes – B6 helps synthesize collagen which is needed for healthy skin.
- Cracked and Sore lips – The corners of your mouth and lips can be dry and painful making talking and eating difficult in severe cases.
- Sore glossy tongue
- Mood changes– B6 is involved in making several neurotransmitters such as GABA and serotine which help control anxiety and depression.
- Weakened immune function – A deficiency in B6 results in the decreased production of antibodies needed to fight infections.
- Tiredness and low energy – Vitamin B6 makes hemoglobin which carries oxygen throughout your body. If you have too little anemia can result, making you feel tired and weak.
- Tingling and pain in hands and feet – A deficiency of B6 results in peripheral neuropathy which may include symptoms such as burning and shooting pains in arms, legs and feet. You could also have balance problems and difficulty walking.
