Introduction
Olive Leaf Extract (OLE) is a supplement derived from the leaves of the olive tree, Olea europaea, and is used for various health benefits, including managing hypertension and glucose homeostasis.
Key Insights from Research Papers
- Olive Leaf Extract administered at a dose of 500 mg twice daily was found to be effective in reducing systolic and diastolic blood pressures in patients with stage-1 hypertension, comparable to the effects of the antihypertensive drug Captopril.
- A daily intake of 500 mg Olive Leaf Extract in tablet form significantly improved glucose homeostasis in adults with type 2 diabetes, as evidenced by lower HbA1c and fasting plasma insulin levels.
- Dietary supplementation with Olive Leaf Extract at levels of 1 and 1.5 ml/kg diet improved growth performance, feed conversion ratio, and carcass traits in growing rabbits, suggesting a dose-dependent effect on health parameters.
Conclusion
The research suggests that a daily dose of 500 mg Olive Leaf Extract is effective for managing hypertension and improving glucose homeostasis in humans. Additionally, higher doses, scaled to body weight as seen in animal studies, may have further health benefits. However, the optimal dosage may vary depending on the specific health goals and individual conditions.
