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 love the flavor, but

    I love the flavor, but it’s grainy and it doesn’t mix well

    Thanks for your review, Ellen! It's great to hear you are loving the flavor. To improve the texture, we recommend mixing your Pre•Bios, waiting a couple of minutes, and mixing again. You can also try mixing with an electric whisk or a high-speed blender. Hope this helps!

    New packaging issue

    I like the product but I recently ordered Pre-Bios in the new bag it is now packaged in, versus the old canister packaging. You may have already gotten this feedback, but the zipper seal will not re-close after opening it. I had to transfer the contents of the bag to a jar to prevent it spilling out of the bag.

    First off, thanks so much for your review and I'm glad to hear you are enjoying Pre•Bios! Thanks as well for the feedback on the new packaging. This is our first batch with this new packaging and we will definitely work to improve it.
