During the unprecedented Coronavirus pandemic, we’ve seen a renewed focus from our customers on ways to “support your immune system.” The obvious question is: can probiotics, by helping your gut be as healthy as possible, also support your immune system? Although probiotics are proven to help digestion and optimal gut health, recent studies indicate probiotics also protect and enhance your immune system.

The primary reason probiotics, by strengthening your gut health, help your immune system function better is simple. Your gut and immune system have a symbiotic relationship. For example, 70-80% of your immune cells are located in your gut. The health of your gut directly impacts the overall health of your entire immune system.

Healthy guts make healthy immune systems. Conversely, compromised, unhealthy guts erode the effectiveness of immune system function. That leads to potentially more illnesses like common colds, flu, and many other infections – potentially even COVID-19.

Scientists have known for years that our microbiome helps keep overactive immune responses (leading to conditions like IBS and other autoimmune diseases) in check. However, they were still unsure of the exact mechanisms that drive this interaction.

Vitamin A

Emerging research may have found one of the potential answers. Vitamin A seems to help the healthy bacteria in our guts produce beneficial chemicals and activate naturally occurring vitamin A found in the food we eat that helps regulate our immune system naturally. After all, our goal as medical professionals is to help your body defend itself from disease naturally without medications, and the frontline of your body’s war against threats from bacteria and viral diseases is in your gut.

A study led by Shipra Vaishnava, Assistant Professor of Molecular Microbiology and Immunology at Brown University, found that when your gut has an adequate level of vitamin A, your gut seems to be able to suppress overactive immune responses. That suggests that instead of your body’s defense system attacking helpful bacteria in your gut and upsetting the natural balance of these necessary flora, they can coexist with each other peacefully; hopefully, leading to a combination of optimal gut and immune system health function.

“A lot of these diseases are attributed to increased immune response or immune activation, but we’ve found a new way that bacteria in our gut can dampen the immune response,” Shipra Vaishnava argues. “This research could be critical in determining therapies in the case of autoimmune diseases such as Crohn’s disease or other inflammatory bowel diseases, as well as vitamin A deficiency.”

Simply put, probiotic supplements give your body the ability to absorb nutrients more efficiently, resulting in an improved immune system. That’s why better gut health prepares your body to defend itself against external threats – even during a pandemic.

Diversifying your Gut to Strengthen your Immune System

Since a COVID-19 vaccine may not be available until sometime next year, anyone looking for ways to build up your body’s defenses naturally should make sure your body has a diverse microbiome which leads to a healthy gut. A health gut, in turn, leads to a more robust, healthier immune system

The best way to increase microbiome diversity is to eat foods that support a healthy gut, and avoiding alcohol and highly processed foods. We get it, that’s always hard to do, and is challenging during a pandemic like COVID-19. One easy way to help your gut stay healthy and strong is to take a multistrain probiotic like EndoMune Advanced Probiotics.

However, don’t forget to help your body stay strong by managing your mental health, getting enough sleep, and staying physically active if you can do so safely.

It’s small, daily steps like these that make a big difference in protecting your health.
