Jarrow Formulas Mastic Gum Capsules

Jarrow Formulas Mastic Gum Capsules

Mastic gum is a resin tapped from the mastic tree (Pistacia lentiscus), a shrub-like evergreen that grows on the Greek island of Chios. People have used it for a very long time. Long before toothpaste existed, the ancient Greeks chewed the hardened resin to freshen their breath. You can still chew it, but most people find a capsule far easier to take. Jarrow Formulas puts the resin into a vegetarian capsule so you skip the strong, piney taste.

What mastic gum is for

This is a single-ingredient supplement. Each capsule contains mastic gum from the stem and branch of the tree, and nothing else active. People reach for it as part of their everyday routine for stomach comfort and general digestive support.* It is not a quick fix, and it will not work the same way for everyone. If your digestion has been off for a while, it is worth talking with a clinician rather than self-treating.

• Supports a healthy digestive tract lining*


• Part of a routine for general digestive wellness*

What is actually in the capsule

The label keeps things short. The only herbal extract is mastic gum (Pistacia lentiscus), sourced from the stem and branch. The capsule shell is vegetarian, made from hydroxypropylmethylcellulose and water, so it fits vegan and plant-based diets. The rest of the list is the usual handful of manufacturing aids: cellulose, magnesium stearate from a vegetable source, and silicon dioxide. It is non-GMO, dairy-free, gluten-free, peanut-free, and shellfish-free.

How people take it

The suggested serving is two capsules a day, and one bottle holds enough for a full month at that pace. Most people take it before breakfast with water or juice, though the label allows for a clinician to suggest something different for you. Mastic gum is a slow-and-steady kind of supplement, so give it consistent daily use rather than expecting an overnight change. If you take medication or have an ongoing health concern, check with your provider before you start.

Who it suits

This one tends to appeal to people who already eat reasonably well and want a simple, traditional, plant-based addition to their digestive routine. It is vegetarian and free of the most common allergens, so it slots into a lot of diets without much fuss. One honest caveat: it is a single herb, not a broad digestive formula, so if you want enzymes or probiotics too, you would pair it with something else or look at our other options.
