Olive Leaf reviews
The use of the products derived from the olive tree on human health dates back centuries. In several civilizations, the olive tree had and still has a very strong cultural and religious symbolism. According to Wikipedia, Olive leaf is the leaf of the olive tree (Olea europaea). Olive leaf extract comes from the leaves of olive tree (Olea europaea), and is distinct from Olive Oil; the leaf extract of olive herb contains phenolics such as oleuropein, and appears to have highly protective effects against LDL oxidation and may also benefit glucose metabolism and skin health.

How Olive Leaf Extract Works
Oleuropein, rich in olive leaves plays an important role in its medical properties. Oleuropein is the polyphenol that can help lower bad cholesterol and blood pressure, prevent cancer, protect against oxidative damage, and help guard against cognitive decline.Oleuropein provides the distinctive tangy, pungent, almost bitter flavor found in high quality extra virgin olive oils. It’s also responsible for most of olive oil’s antioxidant, anti-inflammatory, and disease-fighting characteristics. In fact, when oleuropein was given to animals with tumors, the tumors completely regressed and disappeared in 9 to 12 days!

Health Benefits of Olive Leaf extract Oleuropein
Although researches on the health benefits of taking Olive Leaf extract Oleuropein are limited, some studies suggest that it may offer certain health benefits. Here's a look at several key study findings:
Antioxidant Effect
The antioxidant effect of oleuropein is exerted through different mechanisms, resulting in an enhancement of the antioxidant response. Oleuropein’s antioxidant potential is mainly related to its ability to improve radical stability through the formation of an intramolecular hydrogen bond between the free hydrogen of the hydroxyl group and its phenoxyl radicals.
Anti-Inflammatory and Anti-Atherogenic Effects
Some studies documented that oleuropein elicits anti-inflammatory effects by lipoxygenase activity, production of leukotriene B4, inhibiting biosynthesis of pro-inflammatory cytokines or modulating inflammatory parameters. In particular, Impellizzeri et al. reported that administration of oleuropein in a mouse model of carrageenan-induced pleurisy causes a significant reduction of tumor necrosis factor α (TNF-α), interleukin-1 beta (IL-1β) and nitric oxide (NO).
Anti-Cancer and Anti-Angiogenic Effect
Several epidemiological studies have demonstrated that the incidence of some types of cancer in the Mediterranean basin is lower compared to other areas; this favorable outcome has been ascribed to the Mediterranean diet. The Lyon Diet Heart Study was the first large randomized clinical trial demonstrating the beneficial effects of the Mediterranean diet in reducing mortality by 56% and in decreasing the cancer risk by 61% in a four-year follow up.
Hepatoprotective Effect
Oleuropein administration has an hepatoprotective and therapeutic effects on carbon tetrachloride-induced liver damage in mice. Moreover, a diet supplemented with oleuropein reduces induced hepatic steatosis and progression to non-alcoholic steatohepatitis (NASH) in mice fed with a high fat diet. Data collected in our laboratory confirmed that oleuropein supplementation is able to diminish lipid accumulation in the liver of mice fed with a high fat diet.
Antimicrobial and Antiviral Effects
The presence of oleuropein in several parts of the plant confers to Olea europaea L. natural resistance to microbe attack. Oleuropein exerts its antimicrobial activity against both Gram negative and positive bacteria, including Lactobacillus plantarum, Bacillus cereus and Salmonella enteritidis. Moreover, in vitro studies revealed oleuropein antimycoplasmal activity, also against mycoplasma strains resistant to common antibiotic treatments.
Neuroprotective Effect
Many neurodegenerative diseases, including Parkinson’s and Alzheimer’s, occur as a result of a progressive loss of the structure or function of neurons. Mitochondrial DNA damage and oxidative stress,both key factors in aging, contribute to the development and progression of degenerative diseases. Some studies have been performed in order to evaluate the potential neuroprotection activity of oleuropein. In particular, intra-peritoneal administration of oleuropein once a day for six months in aged rats improved the antioxidant enzyme activities in midbrains in comparison to the control group. Furthermore, treated rats had more neurons in the substantia nigra, revealing that oleuropein protects against dopaminergic neuron loss. This result provides new hope in preventing or attenuating damage or loss of dopaminergic neurons associated with Parkinson’s disease.

Olive Leaf extract Oleuropein Side effects
There have not been any side effects reported yet with olive leaf extract supplement, but few human studies are available.
Olive Leaf extract Oleuropein dosage
The appropriate dose of Olive Leaf extract depends on several factors such as the user's age, health, and several other conditions. Generally, for adults, doses of 1,600 mg per day (divided into four 400 mg doses) have been administered with no significant side effects.
