I decided to summarize the scientific findings on the SARS-CoV-2 coronavirus and the potential mechanism of probiotic supplements in COVID-19 prevention, due to a substantial increase in this type of questions.
At the end of 2019, a new category of coronavirus triggering a series of cases and deaths of pneumonia appeared in the area of Wuhan, China, and then was quickly spreading to many other countries around the world, to turn to pandemic crisis nowadays, according to WHO.
The coronavirus is entirely new to human immune system. No single human being is thought to be subjected to this before the latest outbreak. The immune systems are thus extremely vulnerable to the infection, and thus have not yet had the ability to develop natural resistance to it.
This is among the factors why the infection spreads through the society so dramatically. Health providers are still learning how the infection is transmitted, finding physiopathology linked to its transmission and what the clinical targets and approaches might be possible.
Probiotic Supplements and COVID-19 disease
So there is currently no vaccine or reliable scientifically proven effective treatment available. In this case, the best approaches are to prevent COVID-19 by maintaining good hygiene by cleaning our hands, minimizing direct contact with an infected person and stimulating our immune system.
The human body, and the gut in particular, is host to trillions of healthy bacteria that exist in complete harmony, allowing us consume foods, remove toxins, create active molecules and strengthen our immune system to protect us against dangerous pathogens.
Probiotic bacteria may work with our intestinal flora, improving our immune system, through immune function and encouraging physiologically important immune cell signals.
In recent decades, it has been confirmed that several probiotics can decrease or prevent the average length of bacterial or viral disease.
The combination of probiotics with vitamins may also be a good strategy for generic strengthening of the immune system. For example , vitamin D can amplify innate and adaptive immune responses beyond their effects on homeostasis of the bone and calcium.
Moreover, it has been shown that not only the vitamin D receptor is expressed on the surface of immune cells, but all immunological cells are also capable of synthesizing metabolite of vitamin D.
There is no medical justification that probiotics can be used explicitly to defend, prevent, or treat coronavirus. Despite these facts, I firmly endorse any scientifically based strategy for improving our immune system.
It is essential to help sustain a strong microbial diversity of the gut and prevent intestinal dysbiosis in the seniors, babies, and the overall public.
The combination of a safe and healthy diet with, among others, prebiotics, probiotics, vitamin supplements could help us strengthen our immune system during the COVID-19 outbreak.
