Bye-Lori is a potent and effective dietary supplement containing pure mastic gum from the Pistacia lentiscus tree found in Greece. This potent and effective resin has been used for thousands of years to support gastrointestinal irritations, microbial balance and improved healing responses. In addition to mastic gum's legendary gastrointestinal effects, it has also been shown to reduce the oxidation of LDL (bad cholesterol). Oxidation of the LDL creates a very sticky molecule that is prone to adhering to the artery wall, narrowing the artery opening. Mastic gum is a safe and natural way to support both your GI health and your heart health.
