DAILY HABIT. REAL RESULTS.

See the incredible transformations from our community members who made it a daily habit.

SIX REASONS THIS IS THE NEXT UNLOCK.

Most supplements demand a new routine. This one you just chew. While doing everything else you already do.

🤩

JAW DEFINITION

The masseter is a muscle responsible for the definition and shape of your jawline. High-resistance daily chewing progressively loads it the same way the gym grows other muscles.

01
🦷

ORAL HEALTH

Greek islanders used mastic as primary dental care for centuries before modern dentistry existed. Anti-bacterial, anti-fungal, shown to reduce oral pathogens. Better baseline, full stop.

02
🥗

GUT SUPPORT

One of the only natural substances with clinical evidence against H. pylori, the bacteria behind gastric ulcers. Used in Mediterranean herbalism for digestive support for millennia.

03

ANTI-INFLAMMATORY

Mastic contains triterpenic acids and antioxidant compounds with demonstrated anti-inflammatory activity. Less inflammation, better everything.

04
🎯

ZERO INGREDIENT BS

The label: Mastic Resin (Pistacia lentiscus var. Chia). One line. No flavours, sweeteners, preservatives, aspartame, or anything you'd need to Google.

05
♻️

DAYS PER PIECE

One piece is reusable for up to 5 sessions. Store between chews. The cost per day is genuinely embarrassing for most premium health products.

The Big Chew

Giga Chew has completely changed my routine-finally a gum I can enjoy without stomach irritation. Simple switch, huge difference.
The price is steep, I do wish it was not so or has a loyalty program

Regular gum is terrible for you and this stuff is a underrated superfood forever.

I've seen amazing changes i n my jawline but most of all my digestion has improved a lot.

James R. (Adelaide, AU)

My jawline is actually better so I'll keep buying this. Love the size of the mastic gum

Hey James, thank you so much for your review, you are looking sharp mate, keep it up. We pride ourselves in selling the hgihest quality mastic nuggets you can find so it's great to hear that.

Giga chew is the best mastic gum. I’ve tried different brands but they all failed and I came back to giga chew👍

R
Ryan A. (Adelaide, AU)

This worked for me, if you chew this consistently and trust the process it 100% builds a better jawline, it can be hard to chew for long periods and your jaw sometimes gets sore but its worth it.

Mastic propolis gum

The mastic gum product is great, you guys should consider making a mastic x propolis gum which would be a softer option with the added benefits from propolis. It would be unique to the market

Pieces of gum very small

The flavour is good. Gum is quite hard to chew, which gives my jaw a good workout. However, the pieces of mastic gum I received are significantly smaller than what is depicted in the Tik Tok videos.

Hi there, thank you for sharing your feedback! We're glad you enjoy the flavor and the workout. We've taken this feedback on board and have improved the size and uniformity of the mastic gum we sell recently.

Best Chewing Gum

As someone who cares about my health and wants to look good this is the best thing I've stumbled across, I thought I d have to give up chewing gum for good and now im getting jaw gains whilst receiving health benefits.

🤩 amazing

I love this mastic gun - this gum is a tight substitute for the weak soft gum that I have consumed previously

Mastic Gum

I'm quite happy I found this Gum, it stays tough for a long time and i like the slight pine flavour which lasts the whole time I use it. Would recommend.

Life changing

I brought this cos my jaw clicks when I chew thinking it was always out of place. Ive been chewing for 15days now. My jaw no longer clicks, my cheeks look like they sit higer on my face and my face is looking more snatched. Oh and this gum actually makes you not get a mouth unlike those cheap nastys on the supermarket shelf! I think ive found my new obsession! Who needs botox when you can chew on gum!

I was a sceptic

But it gave me an improved jaw, don't get me wrong tho. I feel like the dominant side is still stronger but my weaker side has definitely improved. Not the same level, I honestly think it will take like a year to get the tendon strength the same as the dominant sides tendon strength. Definite yes th

Couldn’t Be More Happy

First off I’d like to say how helpful customer support was when I had postage issues. My postage service messed up and I hadn’t got my order in 2 weeks. I sent an email to GigaChew and not only did they send a new package same day express post, but threw in some nasal strips for free. I’ve got a deviated septum and those nasal strips work so much better than I ever expected. I’ll absolutely be buying those every month. As for the gum itself, I’ve only just received this so it’s too soon to tell if it works, but the flavour and toughness is exactly what I wanted. If the gum works then I’ll be a returning customer for the gum as well as the nasal strips. Deserved 5 stars

Jawline lookin sharp

I bought this gum awhile ago, got 3 bags and it took about a week of chewing daily for 15-30 minutes and I could feel my jaw muscles getting stronger and bigger - it's essentially a dumbbell for your jaw.The taste is interesting, very natural.

This works better than I expected!

I’ve been chewing Giga Chew consistently for the past 14 weeks, and the results are far better than I expected. To the point where I am getting people constantly commenting on my jaw line which in 39 years has never happened. I will continue to highly recommend Giga Chew because it’s healthy, they’re a great company, and most importantly, it actually works.. I chew during every workout and a little after (minimum 4 times per week) Give it a go!!

God’s Gum

"From the very first bites, you immediately notice the difference. There's no comparison to commercial plastic-y gums. These are natural, hard, and get the job done. With just 20 minutes a day, I feel my facial muscles working hard and I notice improvements. A must-buy.
