How it works
Simple daily routine
1
Start with 1 to 2 pieces
Take 1 to 2 pieces of mastic resin and let them soften in your mouth for 30 seconds before chewing. The resin starts as a firm crystal and becomes gum-like as it warms.
2
Chew 20 to 40 minutes daily
Chew once or twice daily for 20 to 40 minutes. Morning is ideal: activates jaw muscles, freshens breath, and supports digestion before your first meal.
3
Make it a daily habit
Chew daily and keep it part of your routine. Results vary by individual.
Frequently asked questions
What does mastic gum taste like?▾
Mastic has a unique natural taste: pine, eucalyptus, and cedar with a subtle freshness. It's unlike any gum you've had before. Most customers describe it as pleasant and clean. The resin starts firm and becomes more gum-like as it warms in your mouth.
How much comes in one pack?▾
Each Classic Pack contains 25 grams of mastic resin, approximately a 30-day supply when using 1 to 2 pieces per day.
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?▾
We source exclusively from the Chios Mastic Growers Association, the official body of mastic farmers on Chios Island, Greece. This is the only place in the world where mastic resin grows. Each batch is fresh, hand-harvested, and cleaned with spring water. No additives, no processing.
Can I cancel my subscription anytime?▾
Yes. One click, no calls, no hassle. You can cancel, pause, or modify your plan anytime from your customer portal. The 3-Month Supply and 1-Month Supply are both recurring subscriptions (billed automatically), but you're never tied in. We never trap customers.

Awesome gum! I’ll continue to buy!
This mastic is works well. Once you’ve done this long enough it takes about an hour to really feel sore.
110% satisfied, never using a different gum ever again!
Better than I expected!
Never far from me! I practice clean intermittent fasting and wanted a gum that wouldn’t cause a significant spike in insulin. Other sugar free or zero calorie gums still have flavorings that trigger this biological response, but GOG is perfect- no flavor, nothing artificial, long lasting, and satisfyingly tough. Great for those of us who want a clean option for better health and who like to chew on something while working. Highly recommend!
I love this stuff! I wish I would never run out
I enjoy the gum quite a bit. At first, with no flavoring, I wasn't so sure I liked it. I thought it would be better with a mint flavor. However I have gotten used to the no- flavor added, and actually like the subtle flavor that it does have. It does chew very nicely. I am someone who likes to always be grinding away at something.
Store owner replied: Hi Joel, thank you so much for your kind words! We're delighted you enjoyed our gum and appreciate your support :)
Trying in for the first time, but I’m absolutely loving it. It was a little bit weird to chew it for the very first time, but with the second one it felt natural. I think it also might improved my appetite.
Store owner replied: Thank you so much for your kind words! We're delighted you enjoyed our gum and appreciate your support :)
I am excited to chew my Gum of Gods!!!
Goood
The scale from 1 to 10. I give this gum a 10/10 because that fact it has all these health benefits. I have to say this product is one of the toughest gums I ever get my hands on. My face was sore and tired from doing a 4 hours workout. I want to improve my looksmaxx by getting high cheekbone and defining jawline. By 2025, I would have a before and after pictures of my transformation. I want to thank the founder of Gum of God for make this amazing product. It's being in honor to be part of Gum of Gods family!
Store owner replied: Thank you so much for this review Javon. We are so glad to hear you are enjoying the product. Welcome to the Gum of Gods family 🙏
After sucking on the hard resin for a while, it loosens up into a chewy substance that cleans your teeth and refreshes your whole body while also training your jaw
Gum is great! I enjoy the flavor. Only thing I am trying to figure out is that I wish to reuse the gum, but sometimes it begins to crumble when I reuse it.
Fun to chew!
I love it!
It takes getting used to I’ve never tried gum like this! I can’t wait for the peppermint to come out bc I do like this I just wish there was more flavor to it because sometimes it can be off putting for people with over developed taste or if they have stomach issues. I have been suffering from an auto immune disease and have had puffy/swollenface so something like this is so fabulous to me so I can exercise my jaw and when the swelling goes down I’m toned. This is so cool and they even sent little stickers! (I have misplaced them since then :( )
It's really good and works the jaw. I like the taste. It's little bit addictive in a good way.
Nice
I’ve been using it for a couple days so far and I already see progress!
Does what it says it will do. Not the best tasting gum. I will order it again
The tears are great consistency! Not too dry, not too chewy. Great quality overall.
Having mastic gum daily has been a game-changer for me! Good jaw exercise and fresh breath!
Bought this gum for the very first time, and immediately got hooked on its benefits! It's ability to bounce back from being melted, it's chewability is beyond compare! And, as an added benefit is a great sugar free and clean chew that I can use it to aid in my orthodontic pain management to strengthen my teeth as well!! Thanks for an 3xcell3nt product!!!
What would make it better is if the material was shaped into a more consistent form, rather than being loose and varied. Additionally, the initial experience creates too much of an opportunity to swallow the product (exploding into dust before you can form it), requiring a period of spitting, that is kind of a hassle. That being said, I do enjoy the product.
Tough gum and it is very necessary for strong jaw
Wonderful product i love it and will be purchasing more
The original mastic gum is a superb chew with the flavor to transport me to the summit of Mount Olympus.....
Not going to lie, this chios mastic gum is actually legit. It definitely provides an adequate jaw workout/stimulus, and it’s good especially for walking or driving. However, I’ve noticed its positive effects on the gut in realtime - I believe it’s truly helped with my digestion. Definitely reccomend to someone who is interested in trying it.
i am enjoying the excellent quality
This stuff i great, it last me all day.
You could improve: With better order communication. With any kind of response to client emails. With delivering the product - delivery was nearly 6 weeks after ordering again, with no communication.

Store owner replied: Hi Olaf, you're right, and we're sorry. A 6-week wait with no updates and no reply to your emails is not okay. We're working on faster replies. Please email support@gumofgods.us with your order number, or reply to any of our emails, and a member of the team will review your order and your options with you directly. Harris
Product is great. Best mastic on the market imo. Shipping and logistics are horrible. I get that it is coming from overseas, but it’s ridiculous how long it takes for orders to fill. I am 2 months back ordered on my subscription. Very annoying.
Store owner replied: Thank you for your feedback! We are working on the fulfillment situation and it should be resolved soon. Sourcing the highest quality mastic sometimes isn’t the easiest when demand is high 😉
This is the best chewing gum. It's actually perfect for chewing. It really gives your jaw muscles a great workout. And you can save the gum in a glass of water and use it again and again.
I love it, i think its great, I'd chew it for the unseeable future but can not justify spending soooo much on a pack/tin of gum.
Great
Perfect Arrived fast and noticed a big difference in jaw shape.
Good just natural resin
I love this gum! It's natural and I always get the the highest quality pieces.
Great product, but $7+ for standard shipping on a fairly low-weight item that takes 10+ days to get delivered is pretty absurd.
