Why Chios
99% of the world's mastic. One Greek island.
Mastic comes from the resin of a tree that grows almost nowhere else on Earth. Its rarity is part of why most people haven't heard of it, despite a 2,500-year tradition of daily use.
Mastic Gum
Hippocrates wrote about it. UNESCO protects the tradition. This rare resin has been hand-tapped on Chios and chewed for everyday Gut comfort. We've taken that same mastic and put it into a clean daily capsule, made for your modern digestive wellness routine.
Hand-harvested · From Chios, Greece · 2,500-year tradition

Why I made this.
I'm Ryan Natale, founder of The Gastronomy Project.
As a physician, I wanted a clean, traceable digestive wellness supplement I'd actually want to take. Mastic gum has been used for generations in Greece, where 99% of it is still cultivated on the island of Chios. That scarcity is likely why it's underrepresented in the broader health community.
Mastic gum is the centerpiece of this formula. I take it every day, and I can't wait to share it with you.
