For a healthy gut, plus a stronger immune system

Our Gut Gurus designed Immunity to be the all-around probiotic for your immune system and gut. It has five probiotic strains to boost your gut’s immune system. 70% of your body’s immune system resides in your gut, helping you resist infection and recover from illnesses faster. The strains in Immunity also support the production and function of antibodies and strengthen the lining of your lungs for respiratory health. Plus, it contains vitamin C and Echinacea, which stimulates your immune system’s bug-zapping capabilities even further.

Why I made this

You have probably heard the stat that 70% of your body’s immune system resides in your gut. Using the latest research, I was able to pick the individual probiotic strains that best support this critical function of the gut. Given the importance of immunity as we get back out into the world after the pandemic, I also boosted it with Vitamin C and Echinacea to help your body resist infection and recover from illnesses faster.
