Product Benefits
In clinical human research studies, mastic gum inhibited and reduced over-production of foreign organisms in the stomach and duodenum. When digestive flora is imbalanced, mastic gum appears to work on foreign organisms by disrupting their energy production and then rupturing their cells. Some researchers also believe that mastic gum works by stimulating increased production of the protective and soothing stomach lining. Source Naturals MASTIC GUM is standardized to 35% masticonic acids, which are the active compounds that support the lining of the stomach and duodenum. Source Naturals is pleased to partner with your local health food store to bring you MASTIC GUM. Add this ancient Greek secret to your health plan for supporting balanced digestive health today.

Special Note
Mastic gum is a natural resinous gum harvested from a type of pistachio tree, Pistacia lentiscus. There is a legend that when Christopher Columbus was raising funds for his voyage to America, he promised to deliver four precious commodities: gold, spice, cotton and mastic gum. Historically, mastic gum was a prized commodity for many reasons. It was used as a flavoring in foods and beverages such as Ouzo. It was also an ancient Greek remedy used by physicians such as Hippocrates to preserve food, freshen breath, cure gum disease and tonify the digestive tract.

A Must for Nighttime Fetch!!
Color: A) 2-Pack (2.5" Balls)
These are an absolute Must!! We have an ESS who is nearly 2yo and destroys Every toy he has. For some reason, he doesn't try to annihilate these glow balls. If he chomps on them, it's just for a moment while he is bringing it back to you. Has just a little weight to them so it goes far enough when thrown and a nice bounce when we have to play in the house, due to weather. Wish the bright 'glow' held a little longer but stays dim for quite some time and overall, just Awesome! Also purchased the 'chuck it' brand and sent them back because these were so much better. Will be buying more, if ever needed, but haven't had to because they are So Durable.

Awesome quality glow balls
Color: I) 8-Pack (2.5" Balls)
I have bought every glow ball on amazon many times over for my german shepherds. My longest lasting balls have been the chuck-it, they seem to glow longer and not get destroyed but are expensive. These glow balls are our new favorite and not only because of the low price. They hold a good glow longer are heavy duty and fit the chuck-it thrower perfectly. I am stocking up on these. Shipping was also next day so it's 100% buy on these.

Glow in the Dark Balls
Color: 2-Pack (3" Balls)
These balls are ok, not great. The reason they didn’t receive 5 stars is because they are hard/stiff, harder to throw & heavier than the the “Chuck It” glow in the dark balls. They did not hold up to heavy chewers as well as the aforementioned balls.

Awesome quality balls -- my dog loves them!
Color: F) 3-Pack (2.5" Balls)
Love this 3 ball set and variety and quality. These are the 2.5" size, similar to a tennis ball size give or take. The fun citron yellow one is the thickest + heaviest, very bouncy, and tough. The blue is still tough but not as thick or bouncy, a bit more flexible. And the clearish one is the lightest/flexible and is glow in the dark [although we haven't tried that part yet]. I have a 7month old 40lb girl who is becoming like a power chewer on some things -- but hasn't done that with these. She can play, mouth them, chew them, not even one knick or anything. Yes! The citron and blue one we leave out all the time in her little toy box. They have holes in the middle and have used them to hold thinner bully sticks and other treats. The blue one is fun to put smaller treats inside that she can work out like a puzzle. Obviously they are fun for fetch! We leave the other up and only get out when we can play with her because label said it is not a chew toy so we didn't want to take chances. Overall super fun and cool and good quality, human and dog approved LoL. ***We ordered the 2 set of 4" balls, blue and purple [they are same consistency of the blue ball] and love these too! Very fun and good at using with treats the sticks too, plus these don't get lost under sofas and furniture like the smaller ones, a big plus.

Glow and play - pups favorite!
Color: A) 2-Pack (2.5" Balls)
I can't say enough good things about this glowing fetch ball! It's perfect for outdoor play at night—my dog loves chasing it in the dark, and the bright glow keeps the fun going even after sunset. What really impresses me is the quality; this ball has withstood my pup's enthusiastic chewing (and believe me, he can demolish a regular ball in seconds). It’s durable and built to last, making it a fantastic investment for any dog owner. If you're looking for a fun nighttime activity, this glowing fetch ball is a must-have!
