Olive Leaf Extract

What is Olive Leaf Extract?

Olive leaf extract is a dietary supplement derived from the leaves of the olive tree (Olea europaea). It has long been used in traditional medicine, especially in the Mediterranean region, for its potential health benefits. It is rich in a compound called oleuropein, known for its antioxidant and anti-inflammatory properties. Olive leaf extract has recently gained increased attention for its positive effects on heart health, including its ability to lower blood pressure and improve cholesterol profile.

How does it work in the body?

Olive leaf extract acts through several mechanisms in the body. Oleuropein, the active compound in olive leaves, has been shown to affect blood vessels by improving their function and reducing inflammation. This can lead to a reduction in blood pressure and improved circulation. Additionally, olive leaf extract has antioxidant properties, meaning it can help neutralise free radicals in the body. These free radicals can cause cellular damage and contribute to chronic diseases.

Scientific benefits

Several studies have investigated the health benefits of olive leaf extract. Here are some of the most prominent findings:

• Blood pressure: A study published in The American Journal of Hypertension showed that oleuropein can help lower systolic and diastolic blood pressure in individuals with mild hypertension.
• Cholesterol profile: Research has shown that olive leaf extract can reduce levels of LDL cholesterol (the "bad" cholesterol) and increase levels of HDL cholesterol (the "good" cholesterol), which is important for maintaining good heart health.
• Antioxidant properties: According to a study published in Nutrition, olive leaf extract helps reduce oxidative stress, which may help prevent cellular damage and ageing.

Dosage and recommendations

The recommended dosage of olive leaf extract can vary depending on the product and the individual's health condition. Generally, a dose between 500 mg and 1000 mg per day is recommended. It is always best to consult a doctor or nutrition expert before starting a new supplement, especially if you have underlying health issues or are taking medications.

Best sources and forms

Olive leaf extract is available in several forms, including capsules, tablets, and liquid extracts. When choosing a supplement, it is important to ensure the product is of high quality and contains a sufficient amount of oleuropein. It may also be beneficial to choose organic products to ensure they are free from pesticides and other chemicals.

Side effects and warnings

Olive leaf extract is generally considered safe for most people when used at recommended doses. However, some may experience mild side effects such as stomach discomfort, headache, or fatigue. It is important to be aware that olive leaf extract can interact with certain medications, especially antihypertensives and blood thinners. Pregnant or breastfeeding individuals should also consult a doctor before use.
