Mastica Ingredients & Drug Interactions
What is this page for?
First and foremost: checking Mastica against your medications. The heart of this page is the interaction checker and the full interaction report — how this product’s ingredients may interact with prescription and over-the-counter medicines you may be taking.
Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy
Mastica is a dietary supplement by Allergy Research Group with 1 active ingredient. Its ingredients are commonly taken for indigestion and stomach upset, stomach ulcers and h. pylori support, oral and gum health.We don’t currently list a known drug interaction for its mapped ingredients — but that doesn’t guarantee none exist, so always confirm with your pharmacist.
HelloPharmacist Scorecard of Mastica by Allergy Research Group
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
Mastica contains one active ingredient: mastic, a resin from the Pistacia lentiscus tree native to the Mediterranean. The capsule is filled out with inactive ingredients (microcrystalline cellulose, hydroxypropyl methylcellulose, magnesium stearate, and silicon dioxide) — these are standard binders and flow agents with no active role.
Does it work?
Moderate evidence
Mastic is possibly effective for dyspepsia (indigestion and upset stomach). For brittle nails, nonalcoholic fatty liver disease (NAFLD), and cancer, the evidence isn't established enough to rate it — we simply don't have enough reliable data yet to say whether it works for those uses.
How safe is it?
Well-documented data
Mastic taken by mouth is generally well tolerated, though safety data at supplement strengths are limited. Rarely, people report nausea, diarrhea, or constipation; one person's constipation cleared within two days of stopping it.
We don't have enough safety information to recommend medicinal amounts during pregnancy or breastfeeding — talk with your doctor or pharmacist if you're pregnant, planning to become pregnant, or nursing before starting this.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredient we checked in this product.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. No medication interactions are currently documented, and safety information is well characterized.
If you're dealing with indigestion and want to try something with some evidence behind it, mastic may be worth a conversation with your pharmacist. It has no documented drug interactions, but supplement-strength safety data are sparse.
Pregnant and nursing people should check with their provider first.
