Customer

I’ve tried several varieties of mastic gum and none of them come close to the quality of Greco Gum.

Customer

I’ve been chewing these every day for a couple of hours and have noticed real improvement in my jawline.

Ingredients
Our mastic gum nuggets contain one single ingredient: crystallized resin harvested from mastic trees grown on the island of Chios, Greece.
How to use
Chew 30–60 minutes daily. On an empty stomach to prevent bloating and aid digestion, after meals to freshen breath. Anytime to train your jaw muscles and improve focus.
Sourcing
Sourced from the latest mastic gum harvest through the official growers’ association. Pieces are chosen for their purity and then hand-filtered to remove as many sticky pieces as possible before packaging.

Our raw mastic gum nuggets are harvested, cleaned, and sorted by hand. A natural, good-for-you alternative to artificial chewing gums.

Why Greco Gum?

Jaw workout

Chewing our mastic gum gives your 4 core jaw muscles a full workout: masseter, temporalis, lateral and media pterygoid.

Avoid plastic

Pure chiseling with a single, 100% natural ingredient. No silly silicone jaw devices or petrochemical chewing gum required.

Gut check

Mastic gum relieves digestive and gastrointestinal issues due to its powerful antimicrobial, antibacterial, and anti-inflammatory qualities.

Refined taste

The refreshing piney flavor develops from resinous sap that seeps and crystallizes on the bark of the pistacia lentiscus tree.

Rare & beautiful

Chios’s microclimate makes it the only place in the world this gum can be produced. Like snowflakes, no two tears are the same.

What nature wants

Chewing mastic tightens skin and freshens breath while stimulating optimal growth of the maxilla, a wider palate, and larger airways.

Good for your mouth, gut, jaw, and more.

Mastic gum has been treasured for millennia. Its beneficial properties were known to Hippocrates in 400 BC, who recommended it for the prevention of digestive problems, colds, and bad breath.
