You are what you host.

You are what you host.

The old adage goes “you are what you eat”, but recent research shows we’re much more influenced by the bacteria that call our gastrointestinal system home. Our microbiome communicates directly with our body via hormones and other signaling molecules, influencing everything from the foods we crave to our body composition and even our emotional well-being.

Building a diverse gut microbiome of beneficial bacterial species is one of the most impactful things we can do to improve longevity and quality of life. Pre•Bios is formulated with a diversity of prebiotic fibers and starches shown to promote the flourishing of beneficial bacterial species.

    On a keto diet, it’s hard to get a lot of fiber. Pre-Bios mixes up prebiotic fibers and starches for me.

    I have used Pre-Bios for

    I have used Pre-Bios for about 4 years. My Mom who is 98 years old uses it. I like the flavor as it is not strong and blends well with the Synchro genesis powder in a shake or by itself. THe fiber works.
