How to use

  1. Start with Regularity & Constipation Ease, taken at bedtime according to its directions.

  2. Give it a week, then introduce Daily Microbiome Nutrition once things are moving. Begin with ½–1 teaspoon and gradually build toward the full serving over one to two weeks.

  3. Make Daily Microbiome Nutrition part of your daily routine. Choose a time you can stick with.

  4. Adjust Regularity & Constipation Ease as your needs change, following its directions and using the lowest dose that works for you.

“When the gut isn’t moving, adding fiber only adds pressure, which is why this protocol gets you regular first and feeds the microbiome second.”
Our quality standards

What to expect

Get moving first, then build the foundation.

  1. Day 1

    Start with RCE

    Many people notice a movement the next morning, and most are more regular by day seven.*

  2. Week 2

    Add DMN

    Once things are moving, add DMN daily at a time you can stick with. Some early gas is normal and typically settles.*

  3. By Week 4

    Reach the full serving

    You’ve built up to the full DMN serving, which supports regularity with consistent use.* Use RCE at bedtime, as needed.

  4. Once settled

    Find your lowest dose

    Ease back on RCE to what keeps you regular. Continue with DMN as your daily foundation.

    Clearing up lost points

    Had an issue using the website, which was entirely my fault. I visited the site to redeem points, redeemed them, then realised I already had an automatic subscription renewal, so I didn't need to use the points and logged out. The website, however, showed I had no points left, even though I hadn't applied them. I emailed 38Tera, and within minutes they replied that the problem was sorted and my points were applied automatically to my next scheduled delivery. Well done, guys. Fast, efficient, and very friendly service.

    It’s the best!

    So good! It works within a day or two when initially needed and keeps things moving comfortably. I especially appreciate the adjustability of the dose up or down. Prior to using RCE I hadn’t found anything as effective. I use it in conjunction with 38Terra. An unbeatable combination.

    Why I use 38Terra

    I don't use 38Tera for a specific malady. I try to eat a diverse plant-based diet every day. Most of the time, I Ido a pretty great job of eating the right stuff. Occasionally, my life "spins out". I don't resort to eating poorly, but I am more challenged to consume the healthy diversity of plants that keep me stoked! And that is why I use 38Tera , to protect my microbiome from the dips and dives of my busy life and keep me level. I'm 71 and have no intentions of slowing down but feel a stronger need to be more mindful about caring for my microbiome. I know when I've done a good job, because I feel great, feel strong and enjoy superb energy. I have been following the microbiome science since I first read The Gut, by Giulia Enders with my book club in 2018. During the covid era I discovered Dr Will and his book. This science is so exciting,
