Where To Buy Olive Leaf Extract Near Me
The olive leaf is a staple of the Mediterranean diet, which scientists study for its potential to prevent chronic diseases. Research points to lower rates of illnesses and cancer-related deaths among populations that follow this diet. The positive effect is due in part to the powerful and health-boosting benefits of the olive leaf.

Research shows that olive leaf extract helps prevent LDL (bad) cholesterol from building up in your arteries. This effect helps increase blood flow and lower blood pressure, reducing your risk of heart disease.
In laboratory tests, oleuropein lowered body fat and weight gain in animals fed high-cholesterol and high-fat diets. It also reduced food intake, suggesting olive leaf extract can also help manage appetite and overeating.
Olive leaf extract may lower your blood pressure and blood sugar levels. If you have diabetes or are taking medications to manage your blood sugar or blood pressure, talk to your doctor before taking olive leaf extract.
You can buy olive leaf extract as a supplement, tincture, or tea. There are no official dosing recommendation, but studies indicate its health-boosting effects occur when taking 500 to 1,000 milligrams daily.
One small human trial did find that the daily intake of 500 milligrams of olive leaf extract for 14 weeks helped to lower and manage blood sugar in adults with type 2 diabetes. Another review of clinical trials also indicated that olive leaf extract may help reduce blood pressure in humans.

Oleuropein is involved in the antioxidant process.Made from Fresh-Picked Australian Olive Leaves
The daily supplemental dosage is 500 to 1,000 milligrams. You can divide the amount into a few doses per day. Start with a smaller dosage the first time you start taking the extract and gradually increase the dosage as your body allows. Taking olive leaf extract may help with the following:
Olive leaf extract comes from the leaves of an olive plant. It contains an active ingredient called oleuropein. This nutrient is thought to contribute to the anti-inflammatory and antioxidant properties of olive leaf extract.
Olive leaf extract may help lower systolic and diastolic blood pressure. A 2017 study found that olive leaf extract successfully lowered blood pressure. A lower blood pressure can reduce your risk of stroke and heart attack.
In one cell study, olive leaf extracts were shown to stop cancerous cell growth. Researchers suggest that the extract has strong antioxidant properties, but this is also one of the first studies on olive leaf extracts and their anticancer effects. More research is needed to prove this benefit.
Olive leaf extract has not been shown to prevent or treat cancer in humans.Olive leaves contain a substance called oleuropein, which is thought to help reduce cholesterol levels and inflammation. Olive leaf extracts (OLE) also reduce glucose levels in the blood. Laboratory studies found that OLE can kill a number of microorganisms including yeasts, bacteria, and fungi. It was also shown to have anticancer effects, but human studies are needed.
Derived from the olive plant, both olive leaves and the extract have been used to treat infections, inflammation, diabetes, and hypertension. A major component of olive leaf, oleuropein, has been shown to have antioxidant (1) and anti-inflammatory activity (23). Because of its hypoglycemic effects, the leaf extract can induce insulin release and improve peripheral uptake of glucose (2). It also has antimicrobial (3) (22), anti-HIV (4), and anticancer (13) (14) (15) (18) (19) properties. Animal studies showed antiarrhythmic, spasmolytic, diuretic (5), antihypertensive (6), analgesic (20) (21), and cholesterol-lowering (7) effects.Small studies suggest olive leaf extract may reduce blood pressure and have lipid-lowering effects (16) (17) (24). The anticancer effects of olive leaf extract in humans are not known.
The cholesterol-lowering effects of olive leaf extracts (OLE) are thought to be due to oleuropein, a compound present in the leaves. Studies on hypercholesterolemic rats suggest that OLE is more effective than pure oleuropein at lowering cholesterol. This implies that a synergistic effect occurs between oleuropein and another substance within the leaf (7).
Oleuropein is converted into elenoic acid in the body which may prevent viruses and bacteria from replicating (8). The antihypertensive and vasodilating effects of olive leaf occurred independently of the integrity of the vascular endothelium (9). Constituents of olive leaf have been shown to strongly inhibit the complement system, although it is unknown what effect this has on the body (10).
Hypoglycemic activities of olive leaf are attributed to two mechanisms: potentiation of glucose-induced insulin release and increased peripheral uptake of glucose. Hypoglycemic activity is greater in samples collected in the winter months (2). OLE may prevent diabetic neuropathy by reducing glucose-induced apoptosis through the inhibition of neural caspase 3 activation (20).
Antihypertensive drugs: In rat models, olive leaf demonstrated antihypertensive activity (6). Clinical relevance has yet to be determined.Insulin and antidiabetic drugs: In vitro and animal models suggest hypoglycemic effects (2) (6). Clinical relevance has yet to be determined.
The aim of this research was to investigate the activity of a commercial extract derived from the leaves of Olea europaea (olive) against a wide range of microorganisms (n=122). Using agar dilution and broth microdilution techniques, olive leaf extract was found to be most active against Campylobacter jejuni, Helicobacter pylori and Staphylococcus aureus [including meticillin-resistant S. aureus (MRSA)], with minimum inhibitory concentrations (MICs) as low as 0.31-0.78% (v/v). In contrast, the extract showed little activity against all other test organisms (n=79), with MICs for most ranging from 6.25% to 50% (v/v). In conclusion, olive leaf extract was not broad-spectrum in action, showing appreciable activity only against H. pylori, C. jejuni, S. aureus and MRSA. Given this specific activity, olive leaf extract may have a role in regulating the composition of the gastric flora by selectively reducing levels of H. pylori and C. jejuni.
According to many reports, phenolic compounds isolated from olive leaves have very good biological activities, especially antimicrobial. Presently, the resistance of microorganisms to antibiotics is greater than ever. Therefore, there are numerous recent papers about alternative solutions for inhibiting their influence on human health. Olive leaf is studied as an important source of antimicrobials with low cost and used in medicine. Numerous publications on involving green technologies for isolation of active compounds from olive leaves have appeared over the past few decades. The present review reports on current knowledge of the most isolated phenolic compounds from olive leaf extract as well as methods for their isolation and characterization. This paper uses recent research findings with a wide range of study models to describe the antimicrobial potential of phenolic compounds. It also describes the vast range of information about methods for determination of antimicrobial potential focusing on effects on different microbes. Additionally, it serves to highlight the role of olive leaf extract as an antioxidants and presents methods for determination of antioxidant potential. Furthermore, it provides an overview of presence of enzymes. The significance of olive leaves as industrial and agricultural waste is emphasized by means of explaining their availability, therapeutic and nutritional effects, and research conducted on this field.
The present trial aims to evaluate a supplementation of the olive leaf extract (OLE) in adjunct with a weight loss diet on anthropometric indices, glycemic indices, lipid profile, as well as the level of adipokines, and free fatty acid in obese women. We carried out an 8-week randomized, placebo-controlled, double-blind, parallel-group, clinical trial. The participants were randomly stratified according to age and they were assigned to one of the two study groups: Standard weight loss diet (estimated daily energy requirements minus 500 kcal) + OLE supplementation (n = 35) in intervention group or Standard weight loss diet (estimated daily energy requirements minus 500 kcal) + placebo (n = 35) in placebo group. The study groups were homogeneous regarding the baseline age, height, weight, body mass index (BMI), waist circumferences, married status, and physical activity levels (p > 0.05). The results of analysis of covariance presented significant decreases in BMI, fat mass, and body weight in the OLE group compared to those in the placebo group (p 041b061a72
