A 2026 RCT found an olive leaf extract and potassium combination improved home blood pressure readings
In 70 adults with mild to moderate hypertension, a 12-week combination of 1000 mg olive leaf extract (at least 160 mg oleuropein) plus potassium significantly lowered morning systolic blood pressure on 7-day home monitoring, alongside reductions in total cholesterol, LDL-cholesterol, and triglycerides, with no product-related serious adverse events.
Human RCTA 621-patient multicenter trial found olive leaf extract reduced 24-hour blood pressure in treated hypertensives
Adding oral olive leaf extract to existing hypertension treatment significantly reduced 24-hour systolic blood pressure versus placebo, alongside improvements in blood pressure load, diastolic variability, lipid profile, blood glucose, and C-reactive protein, with no significant adverse events.
Human RCTA meta-analysis found higher-dose olive leaf extract lowered blood pressure in pre-hypertensive and hypertensive adults
Pooling 3 eligible trials (248 participants), olive leaf extract reduced systolic and diastolic blood pressure overall, with the largest effect seen at the highest studied dose of 1000 mg/day (systolic -11.45 mmHg, diastolic -4.65 mmHg), though the authors noted variable trial quality and called for more research.
Meta-analysisA systematic review found olive leaf extract reduced LDL and inflammatory markers in hypertensive adults
Across 5 trials (325 patients), 1000 mg/day olive leaf extract reduced LDL cholesterol versus captopril, and 500 mg/day reduced the inflammatory cytokines IL-6, IL-8 and TNF-alpha versus placebo, though the authors cautioned the limited number of participants prevented a robust overall conclusion.
Meta-analysisA crossover RCT found phenolic-rich olive leaf extract lowered blood pressure and cholesterol in pre-hypertensive men
In 60 pre-hypertensive men, 6 weeks of olive leaf extract (136 mg oleuropein, 6 mg hydroxytyrosol daily) significantly reduced daytime and 24-hour systolic and diastolic blood pressure, total cholesterol, LDL cholesterol, and triglycerides compared with a polyphenol-free control.
Human RCTA systematic review of 12 RCTs found olive leaf extract improved cardiometabolic risk factors
Reviewing 703 patients across 12 randomized trials, olive leaf extract was positively associated with improved glucose metabolism, blood pressure, lipid profile, and inflammatory markers, though the authors called for further consistent clinical studies to confirm the findings.
Systematic reviewA phenol-rich olive leaf extract protected neuronal cells from oxidative stress and glycation in the lab
In neuroblastoma cells exposed to inflammatory stress, a phenol-rich olive leaf extract reduced oxidative stress and lipid peroxidation markers and influenced glycation-related gene expression, without exerting toxicity at the tested concentrations.
In vitro studyOlive leaf extracts reduced inflammation and reactive oxygen species in H. pylori-infected human gastric cells
Two olive-leaf extracts significantly decreased interleukin-8 secretion and reactive oxygen species production in human gastric cells infected with Helicobacter pylori, with the oleuropein-rich extract most effective as an anti-inflammatory agent and both extracts showing direct antibacterial activity.
In vitro studyOlive leaf extract showed higher antioxidant capacity than vitamin C in a hypertensive rat model
A standardized olive leaf extract demonstrated higher antioxidative capacity than BHT and a higher reducing ability than vitamin C in the lab, and improved oxidative stress markers at all tested doses in spontaneously hypertensive rats, alongside dose-dependent effects on carotid and renal blood flow.
Animal studyA 2% olive leaf extract ointment outperformed a standard antibiotic in healing infected wounds in rats
In rat models of clean and bacterially-infected wounds, a topical 2% olive leaf extract ointment achieved faster complete wound closure than Fucidin (a standard topical antibiotic), with the extract also showing direct antibacterial activity against both tested pathogens.
Animal studyAn oleuropein-based gel supported fibroblast healing responses and inhibited bacterial biofilm formation in the lab
A thermoresponsive gel loaded with oleuropein-rich olive leaf extract supported fibroblast viability, migration, and collagen-related responses in cell culture, while also showing concentration-dependent inhibition of bacterial biofilm formation.
Laboratory studyAn oleuropein-enriched oral spray gel inhibited major cavity-causing bacteria in the lab
A sprayable oral gel formulated with oleuropein-rich olive leaf extract showed inhibitory activity against all tested cariogenic (cavity-causing) bacterial strains in laboratory testing, with stable physicochemical properties on storage.
Laboratory studyOleuropein showed direct antiviral activity against Herpes Simplex Virus type 2 in the lab
A plant extract containing oleuropein strongly inhibited HSV-2 by direct contact in cell culture, and computational modeling showed oleuropein bound tightly to a key viral surface protein, supporting a plausible antiviral mechanism.
In vitro studyA standardized olive leaf extract showed moderate antiviral activity against SARS-CoV-2 in cell culture
Computational docking first identified oleuropein and other olive leaf compounds as potential inhibitors of several SARS-CoV-2 viral targets; a standardized olive leaf extract (20% oleuropein) was then tested directly against the live virus in cells and showed moderate antiviral activity.
In vitro studyOleuropein inhibited Herpes Simplex Virus type 1 replication in human cells
Olive leaf extracts protected human cells from oxidative stress and, at non-toxic concentrations, oleuropein specifically inhibited HSV-1 viral DNA replication while stimulating cellular antiviral signaling proteins.
In vitro studyAn exploratory lab study found olive leaf extract calmed inflammatory and oil-production pathways in skin cells
In sebum-producing and keratinocyte skin cell models, olive leaf extract and its oleuropein content reduced excess lipid accumulation and lowered inflammatory cytokines (IL-8, TNF-alpha) triggered by acne-associated bacteria and UV exposure - exploratory in vitro findings, not a human skin trial.
In vitro studyA standardized olive leaf extract protected human skin fibroblasts from UVA-induced oxidative damage in the lab
Pre-treating human dermal fibroblasts with olive leaf extract (22.2% oleuropein) reduced UVA-induced DNA damage and reactive oxygen species, and improved cell survival by inhibiting UVA-triggered apoptosis, supporting a photoprotective, antioxidant role in skin cell models.
In vitro studyOlive leaf extracts showed antioxidant, antibacterial, and collagen-production-promoting activity in skin-focused lab testing
Ethanol extracts of olive leaves, which contained oleuropein, showed antioxidant and antibacterial activity and promoted collagen production in cell-based assays, supporting interest in olive leaf-derived compounds for skin care applications.
Laboratory studyA 2026 review summarized oleuropein's antioxidant and anti-inflammatory mechanisms across disease models
This review of oleuropein research described its antioxidant activity, regulation of the body's own redox-related enzymes, modulation of key inflammatory signaling pathways, and suppression of pro-inflammatory cytokine production as central mechanisms behind its broad research interest.
ReviewOlive leaf extract reduced vascular oxidative and inflammatory signaling in genetically hypertensive rats
Long-term oleuropein-enriched olive leaf extract lowered blood pressure and reversed impaired blood-vessel relaxation in hypertensive rats by restoring healthy nitric oxide signaling, reducing oxidative stress enzymes, and lowering pro-inflammatory signaling in blood vessel walls.
Animal studyOlive leaf extract reduced inflammation, oxidative stress, and cell death markers in diabetic rat heart tissue
In diabetic rats, olive leaf extract dose-dependently reduced heart-injury markers and inflammatory cytokines (IL-1beta, TNF-alpha) while increasing antioxidant enzyme activity in cardiac tissue, alongside favorable changes in cell-survival gene expression.
Animal studyA 250 mg/day olive leaf extract RCT in postmenopausal women found exploratory improvements in skin surface quality
In 65 postmenopausal women, 12 weeks of 250 mg daily olive leaf extract - the same per-capsule dose used in this product - did not significantly change most systemic tissue-aging biomarkers, but an exploratory skin-imaging substudy found a reduction in visible pore number and surface irregularity versus placebo.
Human RCTOlive leaf extract normalized diet-induced cardiac, liver, and metabolic changes in rats
In rats fed a high-carbohydrate, high-fat diet, an oleuropein-containing olive leaf extract normalized or improved markers of oxidative stress, cardiac stiffness, liver fat, glucose tolerance, and plasma lipids that were otherwise elevated by the diet, without changing blood pressure in this model.
Animal studyA review described how oleuropein and related olive compounds may help protect against atherosclerosis
This review of olive-derived compounds identified oleuropein and hydroxytyrosol as the major bioactive constituents responsible for antioxidant, anti-inflammatory, anti-platelet, and anti-atherogenic effects observed across rodent and human studies of cardiovascular disease.
