At R’s KOSO, we believe wellness is a shared journey. We are proud to support the creators, athletes, and foundations that inspire us, and our favorite way to do that is by weaving the traditional Japanese art of Koso into the spaces where you move, breathe, and connect.
Our journey started with a slow, year-long fermentation of 100+ fruits and vegetables. Today, that journey continues as we share this ritual with communities across the country, helping individuals build gentle, high-quality gut health habits one sip at a time.

A Pre-Ritual in Detroit with Mark Strong
We’ve spent some wonderful moments with The House of Strong at his "Structural Sculpt" classes. In the heart of Detroit, Mark’s students have been incorporating R’s KOSO as a grounding pre-workout ritual to prep the body from the inside out.

Most recently, this ritual found its way into The Schvitz, a historic bathhouse. Imagine: the rising steam, the body responding to movement, and the quiet internal support of over 100 fermented plants. It’s about creating a structure for your health that feels as natural as the breath you take.
Moments of Flow and Connection
Wellness looks different for everyone, and we love being a small part of that variety:

Finding Balance:
We’ve been joining @laurenewalsh at @rephormpilates, bringing mindful gut-health support to the intentional flow of pilates.
Celebrating Together:
We had the joy of sharing KOSO at a recent gathering with @consciousbuilders, proving that even in moments of celebration, we can nourish our foundation.

Giving with Heart:
It is a true honor to support the Very Asian Foundation with product donations, helping to spread wellness and advocacy within a community we deeply care about.

Let’s Grow Together
We want to keep this momentum going and continue spreading the "KOSO glow." Whether you are a fitness/wellness instructor, a wellness center/ studio owner, or a community leader, we would love to provide wellness support to help your community feel their best.

If you are hosting a wellness gathering or a mindful event, please reach out and say hi. We’d love to see how we can support your journey toward better gut health and holistic well-being.
