A Dietary Supplement MasticBye-Lori II is a dietary supplement containing mastic gum, a natural resin of the pistacia lentiscus tree, cultivated in the Mediterranean for thousands of years. Used traditionally as a food antioxidant, mastic is used today as a chewing gum base and flavoring additive in a wide range of traditional foods and drinks. In addition to mastic, Bye-Lori II contains hyperforin extract, thyme and cinnamon. These phytonutrients, too, have been used widely to increase the enjoyment and benefits of food.
