I was having some chronic stomach issues and decided to give this a try. After one bottle, I noticed a huge difference! I plan on trying the gum next for dental health!

Beautiful packaging, easy-to-swallow size, and no aftertaste. Favorite part is the transparency that Greco has with the only ingredient being Chios mastic gum in a veggie capsule.

    High quality product, the bottles may come caved in a little presumably due to the high heat of summer. But there was no visible damage to any of the capsules inside to my knowledge. Bundling the powder supplements with the gum is a pretty cost efficient way to get the price down as well

    Literally changed my life....

    Literally changed my life. Been dealing with what I’ve “self diagnosed “ a stomach ulcer… so uncomfortable, the endoscopy was going to cost me 2500$ so I decided to just give these a shot, and I’m about 99% better! Only on week 1, buying more for back up and some for my mom who deals with stomach issues as well.

    I have a Helicopt...

    I have a Helicopt P infection, and where antibiotics didn't work, I started using mastic gum. Within a week, I went from diarrhea to a complete recovery of my bowel movements. This product works really well. I took a high dose of the 4-gram tablets per day and the chewing gum. I am very satisfied.
