What is mastic gum?
Mastic gum is the resin (sap that oozes out and hardens) of the mastic tree, which grows on the Greek island of Chios. It's been used for stomach trouble since ancient times.
This resin is sticky and clings to surfaces. So it may help by coating the inner wall of your stomach (the stomach lining), easing irritation from stomach acid.
Mastic gum benefits: where it may help
- Heartburn and acid reflux: Its sticky compounds coat the stomach lining and ease acid irritation. It's especially popular with people whose stomach acid backs up into the esophagus.
- Indigestion and upper stomach pain: Many people who feel bloated and burning without a clear cause say they feel better quickly.
- H. pylori: Research has looked at its effect on H. pylori, a bacterium that lives in the stomach. In one small study, 12 people who took it for 2 weeks saw the bacteria drop by about half.
- Inflammation and germs: It has properties that calm inflammation and fight germs like bacteria and fungi.
- Gut inflammation: In one study, people with gut inflammation took 2 g a day (powder) for 4 weeks and saw meaningful changes.
- Cholesterol: One report found that 1 g a day, split into 3 doses for 8 weeks, lowered bad cholesterol (LDL).
Who should consider it
- □ Heartburn came on suddenly and has lasted several days
- □ You get sour liquid coming up or a burning feeling in your chest (acid reflux)
- □ You have upper stomach pain and poor digestion for no clear reason
- □ Your stomach often burns and is on the sensitive side
- □ You're prone to gut inflammation or often have stomach discomfort
When to take mastic gum and how much
Bottom line: Before meals, starting with 1 capsule (about 250 mg).
- Start with 1 capsule a day. First see whether it agrees with you.
- If it does, you can go up to 3 or more times a day.
- Take it before meals. The idea is to coat your stomach lining first.
| Situation | How to take it |
|---|---|
| Heartburn that's lasted 1–2 weeks | Take it consistently for 2–3 weeks |
| A stomach that's often upset | Take it steadily for 3–6 months |
Unusually for a stomach supplement, it tends to give a feeling of relief right away. That's why many people keep it at home to put out the fire when needed.
Capsules vs chewing gum: which should you choose?
| Form | What to know | Verdict |
|---|---|---|
| Capsules and tablets | Easier to take than powder and easier to dose | Enough for most people |
| Chewing gum | Some say it reduces cavity-causing bacteria, but it makes your mouth acidic, which may be bad for your teeth | Not recommended |
When choosing, just check:
- How many mg of mastic gum per capsule (usually 250–500 mg)
- Whether it's mastic gum alone or a blend with other stomach ingredients
Mastic gum side effects and cautions
It's generally safe, but these reactions can happen.
- Nausea, vomiting, diarrhea
- Allergic reactions: headache, dizziness, hives
If any of these happen, stop and see how you feel.
What pairs well with mastic gum
A safe combo for stomach health is mastic gum + digestive enzymes + glutamine.
- Digestive enzymes: Break food down into smaller pieces to ease the load on your stomach.
- Glutamine: An amino acid that the cells lining your stomach and gut use for energy.
Start with mastic gum alone, and add one at a time if you feel you need more.
Combinations
Works well with: Digestive enzymes, L-Glutamine
Frequently asked questions
When should I take mastic gum?
Take it before meals. The goal is to coat your stomach lining first. Start once a day, and if it agrees with you, you can go up to 3 times a day.
Does mastic gum work right away?
Unusually for a stomach supplement, many people say they feel relief right after taking it. But if your stomach is often upset, take it steadily for 3–6 months.
Can I take mastic gum for acid reflux (GERD)?
It's a popular supplement for people with heartburn from acid reflux. Its sticky compounds may coat the stomach lining and ease irritation. But it's not a medicine, so don't stop prescription drugs without talking to your doctor.
Does mastic gum work against H. pylori?
Its effect on H. pylori has been studied, and one small study reported the bacteria dropping by about half. But the research is small, so it can't replace H. pylori treatment.
