Key benefits

  • Strengthens your core jaw muscles.
  • Supports digestive and gut health.
  • Promotes skin tightening, fresh breath, and optimal maxilla growth.
  • Has a bitter taste that evolves into a blend of pine and cedar-like flavours.

Made from pure mastic gum harvested exclusively in Chios, Greece, each chew of Greco Gum offers a blend of functional benefits and distinctive flavour.

Greco Gum is a 100% natural chewing gum is derived from resinous sap of the Pistacia lentiscus tree, found only in Chios. As you chew, it engages all four core jaw muscles—masseter, temporalis, lateral pterygoid, and medial pterygoid—providing a complete workout that promotes muscle strength and jaw definition.

Unlike synthetic alternatives, Greco Gum is free from artificial additives and plastic materials, ensuring a pure chewing experience without compromising on effectiveness. Its slightly bitter initial taste evolves into a refreshing blend of pine and cedar-like flavours, making each chew both beneficial and enjoyable.

Beyond its impact on jaw strength, mastic gum offers significant digestive benefits. Its antimicrobial, antibacterial, and anti-inflammatory properties aid in soothing gastrointestinal discomfort and promoting overall gut health. Additionally, Greco Gum contributes to tightening facial skin, freshening breath, and supporting the natural growth of the maxilla, which widens the palate and enhances airway capacity.

Logan founded Greco Gum out of necessity and frustration. Having enjoyed mastic gum for over a year, he encountered significant challenges as a consumer. The gum was difficult to get, with long delivery times, high shipping costs, and inconsistent quality from suppliers. Driven by a desire to fix these issues, Logan took it upon himself to source the finest mastic gum directly from producers across Chios. After extensive sampling and careful selection, he identified the highest quality product available. This marked the beginning of Greco Gum, dedicated to treating mastic gum with the respect and care it deserves. Logan's mission is clear: to ensure every customer experiences the true essence of this unique product, without compromise.
