Organic Superpure Olive Leaf Extract
Also known as: Olive leaf extract, OLE, Olea europaea
Overview
Olive leaf extract is derived from the leaves of the olive tree (*Olea europaea*), a rich source of polyphenols, particularly oleuropein. It is primarily used for its potential cardiovascular benefits, including blood pressure management and antioxidant effects. The extract is characterized by its high antioxidant and polyphenol content. Research on olive leaf extract is considered to be at a moderate maturity level, with several systematic reviews and meta-analyses available. However, the quality of evidence is generally moderate due to variability in study designs and sample sizes. Olive leaf extract is available in various forms, including capsules and tablets, and is often marketed as a natural supplement for supporting heart health and overall well-being. Its use is based on the traditional medicinal properties of the olive tree, which have been recognized for centuries.
Benefits
Olive leaf extract has demonstrated potential in reducing systolic blood pressure and LDL cholesterol levels, according to some studies. A meta-analysis indicated reductions in both systolic blood pressure and LDL cholesterol, although the evidence was limited by participant numbers. Secondary benefits may include improvements in glucose metabolism and inflammatory markers, but research results are mixed. The extract may be particularly beneficial for individuals with prehypertension or hypertension. The clinical significance of these effects is moderate, suggesting its potential as a complementary therapy. Consistent use over several weeks to months is typically required to observe noticeable benefits.
How it works
Olive leaf extract exerts its effects through antioxidant and anti-inflammatory pathways, potentially influencing blood pressure regulation and lipid metabolism. It interacts with the cardiovascular and metabolic systems. Oleuropein and other polyphenols in the extract may act on various molecular targets involved in blood pressure regulation. The bioavailability of olive leaf extract components can vary, but they are generally well-absorbed in the body. These mechanisms contribute to the observed benefits in cardiovascular health and overall well-being.
Side effects
Olive leaf extract is generally considered safe when used appropriately. Common side effects, occurring in more than 5% of users, may include gastrointestinal upset. Uncommon side effects, affecting 1-5% of users, may involve allergic reactions or interactions with medications. Rare side effects are not well-documented. Olive leaf extract may interact with antihypertensive medications or blood thinners, potentially altering their effects. It is contraindicated in pregnancy and breastfeeding due to insufficient safety data. Caution is advised for individuals with severe hypertension or those taking medications for blood pressure. It is important to consult with a healthcare provider before using olive leaf extract, especially if you have existing health conditions or are taking other medications.
Dosage
The minimum effective dose of olive leaf extract is typically around 500 mg per day. Optimal dosage ranges are between 500-1000 mg per day. The maximum safe dose is not well-established but is generally considered safe up to 1000 mg per day. It is best taken with meals to minimize gastrointestinal side effects. Common forms include capsules and tablets. Bioavailability may be enhanced when taken with fatty meals. There are no specifically identified required cofactors. It is important to adhere to recommended dosage guidelines and consult with a healthcare provider for personalized advice.
FAQs
Can olive leaf extract interact with medications?
Yes, olive leaf extract may interact with antihypertensive medications or blood thinners. Consult a healthcare provider before use, especially if you are taking other medications.
Is olive leaf extract safe for everyone?
Olive leaf extract is generally safe, but monitor blood pressure if taking antihypertensive medications. It is contraindicated in pregnancy and breastfeeding due to insufficient safety data.
When is the best time to take olive leaf extract?
Take olive leaf extract with meals to reduce potential gastrointestinal side effects. Consistent daily use is recommended for optimal results.
What results can I expect from taking olive leaf extract?
Olive leaf extract may help reduce blood pressure and LDL cholesterol levels. However, it is not a replacement for conventional treatments without medical supervision.
Are there any misconceptions about olive leaf extract?
Olive leaf extract is not a standalone cure for hypertension or hyperlipidemia. It should be used as a complementary therapy under medical supervision.

- https://pubmed.ncbi.nlm.nih.gov/38287654/ – This study is a systematic review and meta-analysis that examined the effects of olive leaf extract on blood pressure and lipid profiles. The key finding was that olive leaf extract may reduce systolic blood pressure and LDL cholesterol levels, although the evidence was limited by the number of participants in the included studies. The study's quality was assessed as moderate due to heterogeneity and limited sample sizes.
- https://pubmed.ncbi.nlm.nih.gov/33868820/ – This systematic review investigated the impact of olive leaf extract on fasting glycemia. The results were mixed, with some studies favoring the control group. The variability in study designs was noted as a limitation, and the overall quality of the evidence was considered moderate due to this variability.
- https://academic.oup.com/nutritionreviews/article/82/12/1710/7591544 – This systematic review and meta-analysis examined the effects of olive leaf extract on blood pressure. The study found some evidence supporting reductions in both systolic and diastolic blood pressure. However, the findings were limited by study heterogeneity, and the overall quality of the evidence was rated as moderate.
