One body. One Earth.

How can we be kinder to both?

We think in systems and sustainability in the pursuit of materials that are not just earth-friendly, but can leave a beneficial footprint. Collaborating with experts in bacteria from around the world, we are working towards biomaterials and unique applications of upcycled waste as an alternative to plastic.

Reduce. Reuse. Recycle. Refill.

Each component of our refill system is designed to protect your Daily Synbiotic and be gentler on our Earth.

Simply keep your jar from your welcome kit and your refill arrives each month.

Welcome Kit

Seed Welcome Kit compostable mycelium tray
Mycelium Tray

Mushrooms grew your tray. Seriously.

Mycelium, the root structure of a mushroom, acts like a natural glue. It binds agricultural waste and turns it into a positive-impact resource, replacing unsustainable synthetics like polystyrene or polyethylene. Bonus: it decomposes naturally in the soil within 30 days.

Corn Foam

To protect your monthly refills, we use an entirely natural and unique insulator made from U.S. grown, non-GMO cornstarch. While most padded mailers are petroleum-based, our corn foam requires 70% less energy and produces 80% less greenhouse gases. It’s biodegradable, backyard compostable, edible, and dissolves in water (seriously, try it).

Certifications: USDA Certified Biobased Product, 100% Compostable (ASTM D6400)
Your move: Place in your compost, your mouth, or under running water. It’ll disappear!
