Olive Leaf Extract Oleuropein Powder

Olive Leaf Extract Powder is a high-purity, standardized botanical ingredient derived from the leaves of the olive tree (Olea europaea L.), a plant native to the Mediterranean region with a long history of use in traditional medicine. The primary bioactive compound in olive leaves is oleuropein – a secoiridoid polyphenol that accounts for the majority of the extract's potent antioxidant, anti-inflammatory, and antimicrobial properties. Through advanced extraction and purification processes, our product is standardized to ≥40%, ≥60%, or ≥80% oleuropein (HPLC-verified), delivering consistent potency for nutraceutical, cosmetic, and functional food applications.

Beyond oleuropein, olive leaves are naturally rich in other phenolic compounds including hydroxytyrosol, tyrosol, and various flavonoids. Hydroxytyrosol, in particular, is recognized as one of the most powerful natural antioxidants, with research demonstrating its significant in vitro antioxidant and DNA-protective activity. Together, these bioactive compounds work synergistically to support cardiovascular health, immune function, and skin vitality, making olive leaf extract a versatile and scientifically validated ingredient.

A comprehensive Certificate of Analysis (CoA) is available for every batch, with batch‑specific HPLC chromatograms.

1. Potent Antioxidant Protection

Olive leaf extract is rich in polyphenols that combat oxidative stress by neutralizing free radicals. This helps protect cells, DNA, and tissues from damage caused by environmental stressors, supporting overall health and healthy aging. Hydroxytyrosol-enriched extracts have demonstrated significant in vitro antioxidant and geno-protective activity.

2. Cardiovascular Health Support

Olive leaf extract has been shown to promote cardiovascular health by helping to maintain healthy blood pressure and reducing LDL oxidation. The phenolic compounds in olive leaves, particularly oleuropein and hydroxytyrosol, are responsible for antioxidant, anti-inflammatory, and anti-atherogenic activities.

3. Immune System Modulation

Olive leaf extract supports immune function by modulating inflammatory responses and reducing oxidative stress. Clinical studies have demonstrated its ability to improve key inflammatory and immune markers, making it a valuable ingredient for immune-support formulations.

4. Skin Health & Anti-Aging

In cosmetic applications, olive leaf extract offers multiple skin benefits. Oleuropein has been shown to increase collagen synthesis and inhibit matrix metalloproteinases (MMPs) – enzymes that degrade skin collagen and elastin. It also exhibits anti-collagenase, anti-elastase, and anti-tyrosinase properties, supporting wrinkle reduction, skin elasticity, and even skin tone. Rich in antioxidants, the extract helps combat free radical damage and protects skin from premature aging and environmental stressors.

5. Natural Antimicrobial Activity

Olive leaf extract has demonstrated antimicrobial properties that support oral health and help protect against harmful microorganisms. These properties also make it a natural option for preservation in cosmetic and food applications.

6. Metabolic Health Support

Research indicates that olive leaf extract may help support healthy glucose metabolism. Studies in animal models have shown its potential to restore glycemic balance and support pancreatic function.

1. Nutraceuticals & Dietary Supplements

Olive leaf extract is widely used in dietary supplements for its cardiovascular, immune, and antioxidant support benefits. It is available in:

• Capsules and tablets
• Powder blends and sachets
• Liquid extracts and tinctures
• Functional beverage formulations

Recommended Dosage: 100–500 mg per serving (depending on oleuropein standardization).

2. Cosmetics & Personal Care

In skincare, olive leaf extract is incorporated into a variety of products for its anti-aging, soothing, and protective properties:

• Anti-aging serums and creams
• Soothing lotions and toners
• Sun protection products
• Hair care formulations
• Face masks and cleansers

Recommended Concentration: 0.5% – 3.0% in finished formulations.

3. Functional Foods & Beverages

Olive leaf extract can be added to functional foods and beverages to enhance their nutritional profile with natural antioxidants:

• Fortified juices and wellness shots
• Health bars and snacks
• Yogurts and dairy alternatives
• Herbal teas and functional drinks

4. Natural Preservative

Due to its antimicrobial and antioxidant properties, olive leaf extract serves as a natural preservative in both food and cosmetic products, helping to extend shelf life and maintain product stability.

1. General Safety: Olive leaf extract is generally considered safe for consumption and topical use, with a history of use in traditional diets. Most reported side effects are mild and related to digestion (e.g., occasional stomach discomfort).
2. Drug Interactions: Consult a healthcare professional before use if you are taking medications. Special caution is advised for individuals on:
3. Blood pressure medications, as the extract may enhance their effect.
4. Blood sugar-lowering drugs (e.g., insulin), due to their potential hypoglycemic properties.
5. Certain chemotherapy drugs have antioxidant activity.
6. Special Populations: Safety for young children, pregnant or nursing women, and individuals with severe liver or kidney disease has not been conclusively established.

• For Nutraceutical Products (e.g., capsules, tablets): Follow standardized extract recommendations. Typical olive leaf extract capsules provide a concentrated dose of polyphenols. Dosage should be based on the standardized content of active compounds (e.g., oleuropein).
• For Cosmetic Formulations: Can be incorporated into serums, creams, lotions, and masks. Add to the water phase at low to moderate temperatures. A typical usage range is 0.5% - 5%.
• For Functional Foods & Beverages: Due to its solubility and potential bitter taste at high concentrations, it is best used in encapsulated form or in strongly-flavored products.
