      What's in the The Mastiha Protocol
      One tin is a 30-day supply. Pick a supply length that fits your routine, and the price per tin drops the longer you go.
      The research behind mastic
      Mastic is the only tree resin with published randomized trials on cholesterol, H. pylori and gut inflammation. These studies used mastic capsules or powder, not chewed gum. Clinicians receive no compensation for recommending it.

      Why buy the full routine
      Mastiha works on a cycle.
      Buy the cycle, not the tin.
      ⏳
      Mastiha Is Measured in Weeks, Not Days
      The cholesterol RCT ran 8 weeks. The H. pylori work ran a month. Every documented benefit of mastiha is measured over a cycle, and a single tin is 30 days, which is why one-tin buyers quit before anything has had time to happen.
      ✓ 4 tins is the shortest honest trial
      🌲
      Harvested Once a Year
      Mastic resin grows only on Chios, and the trees are tapped once annually. Every tin you receive traces back to a single harvest window on a single island, which is why we buy direct from the growers cooperative rather than through a broker.
      ✓ Subscribers ship first from every new harvest
      🍃
      All Four Flavors, Every Box
      Classic, Premium, Peppermint and Maple Syrup in an even split. Rotating flavors is the single biggest reason people stay consistent past week three, and consistency is the whole mechanism.
      ✓ Even split across every supply length
      💰
      The Longer the Supply, the Lower the Tin
      Bought separately, these four tins average $67.49 each. On the 12-Month Supply they are $37.33. Same resin, same island, same tin. You are paying for the privilege of buying in small pieces.

      How it works
      Simple daily routine
      1
      Warm it before you chew
      Take 1 to 2 pieces and let them soften in your mouth for 20 to 30 seconds before biting down. That single step is the difference between a smooth chew and a crumbling one.
      2
      Chew 20 to 40 minutes daily
      Chew once or twice daily for 20 to 40 minutes. Morning is ideal. Sip cold water while you chew to keep the resin firm instead of sticky.
      3
      Give it a full cycle
      Chew daily and keep it part of your routine. Results vary by individual. Full guide at how to chew.
      Frequently asked questions
      Which flavors come in the box?▾
      Every supply ships an even split of Classic, Premium, Peppermint and Maple Syrup. A 4-month box is one of each. An 8-month box is two of each. A 12-month box is three of each.
      What is in the Premium tin?▾
      Classic Chios resin coated in pine pollen powder and pine pollen tincture. Pine pollen is a botanical with a long history of use in traditional Chinese practice, and it naturally contains amino acids and trace minerals. Skip the Premium tin if you are allergic to pine or tree pollen. If you are pregnant, nursing, or taking medication, talk to your doctor before use.
      How long does each tin last?▾
      Each tin holds 25 grams of mastic resin, about a 30-day supply at 1 to 2 pieces per day. That is why supply length and tin count are the same number: an 8-Month Supply is 8 tins.
      Is it safe for people with dental work?▾
      Mastic resin is significantly harder than regular gum. We recommend avoiding it if you have fillings, crowns, veneers, or other dental work. Please consult your dentist if you're unsure.
      How is your mastic sourced?▾
      Single origin Chios mastiha, sourced direct from the growers cooperative on Chios Island, Greece. This is the only place in the world where mastic resin grows. Each batch is hand-harvested and cleaned with spring water. No additives, no processing.
      Can I cancel anytime?▾
      Yes. One click, no calls, no hassle. You can cancel, pause, or change your supply length anytime from your customer portal. Every bundle is a recurring subscription billed automatically at the end of your supply.
      What's the return policy?▾
      Questions about your order? Contact us any time and our support team will help.

      Customer Reviews

      Overall rating: 4.9 / 5 from 177 reviews.

      Sorry I didn't respond, out of the three I dislike the all natural pack the most, because of its bitter taste. It's ok because it's called the all natural flavor. I think this a process I don't really chew a lot because my right side of my face gets swollen when I chew with my left side a lot. It's more than just chewing gum for me.

      3-Gum Bundle

      Customer photo review of 3-Gum Bundle

      Unfortunately all my gum arrived melted, so that’s why 3 stars and also there was a 3-4 month waiting period to receive the gum. Taste rating: #1 peppermint flavor the best. Lasts long and love the taste. It’s natural and refreshing. I had to take breaks while chewing because it is a jaw workout. Premium “the yellow one” - tasted like pickles, idk if the heat affected the taste for that. Usually I like pickles but didn’t like this one. Classic flavor- also didn’t like its taste or after taste. Maybe it’s heat affected but I can’t tell.

      3-Gum Bundle

      Store owner replied: Hi Karen, thank you for the detailed review, and we're sorry it took so long to reach you and arrived melted. That isn't the experience we want for anyone. Summer heat in transit can soften natural mastic, and we're looking at how we pack and ship in warm months. We'd like to look into your order personally, so please email support@gumofgods.us with your order number and a photo if you still have one. Glad Peppermint was a hit. Premium and Classic are more resin-forward, so they're not for everyone. Harris

      Customer photo review of 3-Gum Bundle

      The gum in the tins arrived melted together. A bit difficult to separate into pieces. Otherwise a great chew

      3-Gum Bundle

      Store owner replied: Thanks Brian, and sorry about the stuck-together pieces. Summer heat in transit can soften natural mastic, and we're improving how we pack in warm months. A few minutes in the fridge makes the pieces easier to separate. If anything else is off, email support@gumofgods.us. Harris

      Classic is pretty good, haven’t tried much of the peppermint, don’t think the premium is really my style It’s fun gum to hand out to people, they aren’t sure what it is so I have to explain

      I love this gum! My only complaint is that it seems like a small amount is actually inside the tins VS what is advertised. Also the pieces are very tiny in a couple of the tins. Other than that, love the flavors and toughness of the chew!
