You want a mastic gum capsule that actually contains mastic gum — and that is the whole problem with this shelf. The resin is expensive, so some bottles get cut with fillers, and you cannot tell by looking at a capsule. The short answer: the NOW Supplements Gastro Comfort is the safest first buy because it pairs mastic gum with aloe vera and slippery elm for a gentler stomach, and its label quality holds up better than most. Below are five real bottles, what each one actually delivers, and which one fits your gut issue.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Mastic gum is a tree resin, so purity and dose matter more than fancy label language. This guide breaks down the best mastic gum supplement options by capsule strength, added ingredients, and honest buyer experience.
Top Picks
How To Choose The Best Mastic Gum Supplement
Mastic gum is a resin tapped from the mastic tree, and it is sold as a powder inside a capsule. The two things that decide whether a bottle is worth your money are how much resin is in each capsule and whether the powder is actually resin. Everything else is detail.
Check the dose per capsule, not the bottle size
A 500 mg capsule and a 1000 mg capsule are not the same product with a different count. The higher-dose bottle usually means fewer capsules per day to reach the same amount of resin. That matters if you dislike swallowing pills or want a simple routine.
Read the ingredient list for extra herbs
Some bottles are pure mastic gum and nothing else. Others add aloe vera or slippery elm to soften the stomach effect. Neither is automatically better. Pure resin gives you a clean dose you can combine yourself; a blend saves you buying three bottles.
Judge purity by smell and taste, not the label
Real mastic resin has a distinct pine-and-medicinal smell, and the powder is sticky when it touches water. A capsule that smells of nothing and tastes like flour is a warning sign. Buy from a seller with a clear return path in case a bottle arrives wrong.

Detailed Reviews
1. NOW Gastro Comfort
Our pick — 4.5+★ from 550+ verified ratings; the strongest balance of quality and price.
The bottle that treats mastic gum as one part of a stomach blend, not the whole show.
This is the pick for someone whose stomach reacts to a bare resin capsule. Each veg capsule carries mastic gum alongside aloe vera and slippery elm. Aloe vera is a soothing plant gel; slippery elm is a bark powder that coats the stomach lining. Together they make the dose feel gentler.
The routine is simple: one capsule twice daily, with or without meals. The label also carries NPA A-rated GMP certification, which means an outside body has inspected the manufacturing process and lab testing — not just the finished pill. Packaged in the USA by a family owned company since 1968. At 2.4 ounces it is a small bottle that fits any kitchen cabinet.
Here is the honest part. Among the digestive-support bottles on this list, this one draws the most mixed feedback on how well it works — people who feel a difference and people who feel none. It is a blend, so you cannot separate how much relief comes from the resin and how much from the aloe and elm. For most, that blend is the point; for a purist chasing a clean single-ingredient dose, it is not.
Why it leads: It is the gentlest entry point on this shelf. Three soothing ingredients in one capsule mean you skip building your own stack — and the certification is a real quality signal, not just a badge on the front.
Know before you commit: Long-term users report it can start to feel rough if taken every single day for weeks without a break. Cycle it, and stop if your stomach gets sore rather than pushing through.
Right for you if: you want one bottle that covers mastic gum and stomach-coating herbs together, with a certified manufacturing process behind it.
Think twice if: you need to isolate mastic gum alone to judge whether it works — a blend hides that answer.
2. HERBAMAMA Mastic Gum Capsules – Gut & Digestive Support
Two ingredients, one of them the capsule itself — the shortest label here.
For anyone who reads every line of an ingredient panel, this is the shortest one on the list. Inside is mastic gum powder and a vegetable cellulose capsule. No fillers, no artificial colours, non-GMO, and vegetarian. Swallow one capsule whole with water or juice, twice daily, ideally with meals.
It sits in a 3.22-ounce bottle, a touch heavier than the NOW blend — but that extra weight is resin, not added herbs. The formula is built for people who want to combine mastic gum with their own stack rather than buy a pre-mixed blend.
The trade-off is real and worth saying plainly. Some people who open a bottle report the powder smells of nothing and tastes like flour, not resin — the opposite of what pure mastic gum should do. Real resin has a sharp pine smell. So check your first capsule before you commit to the whole bottle, and use the return window if it seems off. Separately, users on ulcer medication often note it works best as an add-on, not a replacement.
What earns it a place
- Just two ingredients, both plant-based, with no filler or artificial colour
- Easy to swallow for people who dislike large tablets
- Pairs cleanly with other gut supplements because nothing is pre-mixed in
- Odour-free capsule form suits people who dislike chewing resin
Where it can disappoint
- Consistency varies — a bottle can arrive smelling and tasting nothing like resin
- No certified lab claim on the label, so you are trusting the seller
- The two-ingredient formula gives no soothing herbs to soften the dose
Go for it when: a clean, vegan, filler-free panel is your top priority and you already know your gut tolerates straight resin.
Pass if: you want a certified purity paper trail on the bottle — this one does not print one.
3. Best Naturals Mastic Gum 2 Pack
A two-bottle set that splits the dose into small 500 mg capsules you can space through the day.
Two bottles, 60 capsules each, 120 in total, with 500 mg of mastic gum in every capsule. That is the appeal here: a smaller dose you can take before a meal you are worried about, then again later. The powder is third-party lab tested for purity and quality, and the bottle is non-GMO and gluten-free. It is made in the USA in a GMP-compliant, FDA-registered facility.
The label is unusually thorough about what is not in it: no artificial colour, flavour or sweetener, no preservatives, no sugar, milk, corn, soy, egg, lactose, gluten, wheat, yeast or fish, and it is sodium free. That list matters if you have food sensitivities on top of a stomach problem.
Compare the footprint: this two-pack weighs 8.01 ounces and measures 4.33 x 0.79 x 4.72 inches, against the NOW bottle at 2.4 ounces and 1.95 x 1.95 x 4.3 inches. The gap is the second bottle — this is a set, not a single. The recurring question from buyers is whether the powder is truly pure mastic gum; the purity test claim on the label is the answer to weigh.
The split-dose advantage: When the burn hits after eating, a 500 mg capsule gives you room to take a second dose the same day without overshooting the amount you meant to take. That flexibility is why people who eat out often keep a bottle in the bag.
Best match for: someone who wants a low 500 mg dose they can take several times a day, backed by a printed lab test and a free-from list.
Less ideal if: you would rather swallow one stronger capsule than several smaller ones.
4. Premium Mastic Gum Capsules
Twice the resin strength of the 500 mg bottles — the one to pick when you want fewer capsules.
Each serving here is 1000 mg of mastic gum, double the per-capsule strength of the Best Naturals bottle. If swallowing pills is the chore, this cuts the count in half for the same amount of resin. The resin is sourced from the mastic tree, Pistacia lentiscus, in a 120-capsule bottle.
The formula has no unnecessary additives, according to the maker, and the capsule form is vegan. It is built to slot into a daily routine — one serving a day rather than a capsule every few hours.
The honest downside: this is the bottle where scepticism about mastic content runs highest. Some buyers open it expecting a sticky, pine-scented powder and find something that does not behave like resin. Real mastic powder clumps and sticks when you wet it; if your capsule contents pour out like dry powder, treat that as a question mark. The higher dose also means a stronger hit on a sensitive stomach, so start with one serving before settling into a routine.
Where it shines
- 1000 mg per serving — the strongest dose of the five bottles here
- Fewer capsules to swallow each day for the same resin amount
- Vegan capsule with no unnecessary additives listed
- 120 capsules in one bottle, so a single bottle lasts
The honest catch
- Resin feel is inconsistent — some bottles lack the sticky texture and pine smell
- Higher dose can be too strong for a very sensitive stomach
- Not always easy to return if a bottle seems wrong
Choose this one if: you want a single strong serving a day and are comfortable checking the powder yourself on the first capsule.
Look elsewhere if: your stomach is easily upset — the 500 mg options let you start smaller.
5. Vitamatic Mastic Gum 2 Pack
Two bottles, 240 capsules, 1000 mg per serving — the biggest supply on this list.
If you plan to take mastic gum long term, this is the bottle count that makes sense. Two bottles, 240 capsules, at 1000 mg per serving. The label also positions it for more than digestion: respiratory function, oral health, circulation and liver function support all appear on the front. It is non-GMO, gluten-free, and free of sugar, starch, soy, yeast, corn and wheat. Made in the USA under GMP standards.
The practical read: this is the longest runway between reorders of the five, so it suits someone who has already decided mastic gum works for them and does not want to shop again soon. It is also the biggest physical commitment — 7.05 ounces across two bottles, so it wants shelf or cupboard space rather than a travel bag.
Worth knowing before you order: buyers have reported the occasional second bottle arriving with the wrong capsules inside — lighter, tan-coloured, and missing the resin smell. That is rare, but it means you should open both bottles and smell the first capsule rather than trusting the seal. Others pair it with berberine and diet changes and say mastic gum works better alongside other habits than on its own.
The long-haul case: 240 capsules at 1000 mg per serving is the supply that keeps you from running out mid-routine.
The honest caveat: the bigger bottle count only pays off if the contents are right — check the first bottle’s smell and texture before you rely on the second.
Made for: a committed daily user who wants the largest supply and the 1000 mg dose in one order.
skip it if: you are still testing whether mastic gum agrees with you — start with a smaller bottle first.
Know the Specs
Dose Per Capsule vs Per Serving
Labels mix two numbers: milligrams per capsule and milligrams per serving. The 500 mg bottles list it per capsule; a 1000 mg label usually means per serving, which may be more than one capsule. Reading which one you are looking at tells you how much resin each swallow actually delivers.
Purity and Lab Testing
Mastic resin is costly, so some products get cut with cheaper powders. A third-party lab test on the label, or a GMP certification, is the best proof you have. Failing that, the smell and stickiness of the powder when wet are your next check.
Common Questions

The Bottom Line
For most people, the mastic gum supplement to start with is the NOW Supplements Gastro Comfort because it softens the resin with aloe vera and slippery elm and carries a certified manufacturing process. If you want a clean, two-ingredient panel, reach for the HERBAMAMA capsules. And if you would rather swallow one strong capsule a day, the Premium 1000 mg bottle gives you the higher dose in a single serving.
