Description of Mastic Gum Powder Capsules
Mastic Gum Powder Capsules are the non chewing version of the same raw material Greco Gum sells as resin tins. One bottle holds 60 vegetarian capsules, each filled with 500 mg of Chios mastic that has been cleaned, ground to a fine powder and freeze dried. The shell is hypromellose, so the product suits vegetarians and vegans.
The reason this format exists is practical rather than nutritional. Raw mastic is hard enough that Greco Gum publishes a dental warning about crowns, fillings and braces, and 30 to 60 minutes of daily chewing does not fit every jaw or every schedule. Capsules remove both problems. What they also remove is the chewing itself, which is the part of the ritual most buyers of this brand say they are paying for.
Composition of Mastic Gum Powder Capsules
The formula is a single ingredient with a single excipient. There is no filler, no flow agent declared, no botanical blend and no standardized extract percentage, because the capsule holds the ground resin itself rather than a concentrate of it.
- 500 mg of ground Chios mastic resin per capsule
- 60 capsules per bottle, which is 30 g of resin in total
- Hypromellose vegetarian shell, no gelatin
- No filler, binder, sweetener or added botanical
Ingredient Sourcing and Origin of Raw Materials
The resin is bought from the latest harvest on Chios through the official Chios Mastiha Growers' Association, the same supply route as the tins. It is then cleaned in reverse osmosis water, ground fine and freeze dried before encapsulation, which Greco Gum says takes place in GMP and NSF certified facilities. Its About page describes the same facilities as FDA certified, a different and looser wording that the brand should reconcile.
Testing is documented. The certificate of analysis on the site is issued by RL Labs, dated 8 September 2025, and uses ICP-MS, HPTLC and USP methodologies. Arsenic, cadmium and mercury came back below the limit of detection and lead below the limit of quantification. Plate count, yeast and mould and Enterobacteriaceae were each under 10 cfu/g, with no E. coli, Salmonella or Staphylococcus aureus detected, and HPTLC confirmed the identity as Pistacia lentiscus. Note that the capsule page carries a verified badge dated June 2026, later than the certificate you can actually download.
How to Take Mastic Gum Powder Capsules
Greco Gum directs one to two capsules a day, taken about 30 minutes before a meal on an empty stomach and with plenty of water. Inside its Gut Health Protocol the brand uses a heavier pattern, three capsules a day for 20 days, then two a day to maintain.
- Take 30 minutes before food, not with it
- Use a full glass of water, the powder is a resin
- Pick one dose and keep it stable rather than moving between one and three
- Ask a doctor first if pregnant, breastfeeding or on any prescription
Price and Where to Buy Mastic Gum Powder Capsules
A single bottle is $36.98 on the official store as a one time purchase, and our code LMC brings it to $33.28. At the two capsule daily dose the bottle covers 30 days, so that is about $1.23 a day, or $1.11 with the code. Take one capsule a day and the same bottle stretches to 60 days at roughly $0.62.
Volume pricing runs 5 percent on two bottles and 15 percent on four, and subscriptions go from 10 to 25 percent. We verified in the cart that LMC applies on top of the automatic bundle discounts rather than replacing them. Greco Gum also sells the capsules inside the Gut Health Protocol with a 45 g tin of nuggets at $62.22. You can order the mastic capsules on the official Greco Gum store.
My Take on Mastic Gum Powder Capsules
This is the format I would choose for anyone who wants Chios mastic without risking dental work, and it is the only sensible option if you have crowns, veneers, braces or a jaw that already complains. The sourcing and the certificate carry over unchanged from the tins, which is the important part.
Two things hold me back. The first is the marketing, which is noticeably more medical on this page than on the resin tins and reaches for digestive and bacterial claims the label does not carry. Read it as a food supplement, not as a treatment, and speak to a doctor about any ongoing digestive symptom rather than self managing it. The second is value: at the two capsule dose the capsules cost more per day than the 45 g tin of nuggets, so you pay a premium for convenience. Anyone comfortable chewing will get more resin for their money from a tin. Check also that the first order guarantee, which stops at $100, covers the size of basket you are planning.
