Research-Supported Benefits:

Promotes Healthy Immune Response: Oleuropein, one of the primary bioactive compounds in olive leaves and olive oil, is responsible for making the olive tree resistant to pathogens. When used as a supplement, it has been shown to have a similar effect on our immune system. By helping the body’s immune system to adapt to triggers, it helps reduce the overall inflammatory burden seen in aging broadly described as inflammaging.(1)

Supports Heart Health: Oleuropein has shown to have numerous positive effects on heart health including supporting blood pressure, circulation and improving blood markers of heart health.(2-5)

Anti-Inflammatory Properties: The active ingredient in Olive Leaf Extract, oleuropein, has shown to have strong anti-inflammatory properties which can reduce oxidative stress, a leading driver of aging and chronic health concerns.(3)

Supports Healthy Blood Sugar Management: Managing glucose (blood sugar) levels becomes more difficult as we get older even with a healthy diet. Oleuropein has shown to help maintain healthy blood sugar levels.(6)

  • The active ingredient in olive leaf capsule extract is called oleuropein. Oleuropein is a polyphenolic fraction derived from the fruit, leaves, bark and roots of the olive tree, which help make it strongly resistant to damage from insects and other factors.
  • Oleuropein is a chemical agent called elenolic acid, which has been shown to assist the body's immune defense.
  • Research studies have found that elenolic acid helps the body to balance levels of friendly bacteria and support the immune system. The energy-boosting benefits of olive leaf extract are believed to be the result of its ability to help fend off fungi, which overtax the immune system, and yeast overgrowth, which cause fatigue. The olive leaf capsule contains extract that provides nutritional support for detoxification at the cellular level, when the body is under stress.
  • It has been shown to protect RNA structure. Oleuropein imparts some important antioxidant benefits that may help reduce the build-up of LDL “bad” cholesterol and support healthy heart function.
