Hydroxytyrosol, scientifically known as 3,4-dihydroxyphenylethanol, is a highly active polyphenol compound extracted from olive fruits and leaves, possessing a unique molecular structure. The catechol group in its molecule acts as a powerful free radical scavenger, giving hydroxytyrosol exceptional free radical scavenging capabilities and making it outstanding in the field of antioxidants. As a major metabolite of oleuropein, it is naturally present in olives and is one of the key components responsible for the numerous health benefits of olives.
To obtain high-purity hydroxytyrosol, 98% high-purity hydroxytyrosol powder is refined from high-quality olive oil using advanced low-temperature extraction technology. This process is meticulous and must be carried out at low temperatures to avoid damaging the activity of hydroxytyrosol. From carefully selecting high-quality olive raw materials to using low-temperature extraction technology, every step is strictly controlled to maximize the preservation of hydroxytyrosol’s natural activity, allowing it to fully exert its effects in subsequent applications.
Hydroxytyrosol’s antioxidant capacity is considered a “superstar in the antioxidant world.” Measured by its oxygen radical absorbance capacity (ORAC value), it reaches 4,500,000 μmol TE/100g, a number that vividly demonstrates its powerful antioxidant strength. Compared to common antioxidants such as vitamin C and vitamin E, hydroxytyrosol’s antioxidant capacity is 40 times that of vitamin C and 10 times that of vitamin E. Even traditional antioxidants known for their antioxidant properties, such as green tea and resveratrol, are slightly inferior to hydroxytyrosol.
The reason for hydroxytyrosol’s powerful antioxidant activity lies in its unique antioxidant mechanism. It acts like a multi-talented agent, not only clearing various free radicals such as superoxide anions and hydroxyl radicals, directly reducing free radical attacks on cells from the outside; but also penetrating deep into the cells, activating the Nrf2 pathway, and enhancing the activity of endogenous antioxidant enzymes, such as superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). This dual protection system of “exogenous scavenging + endogenous activation” allows hydroxytyrosol to form a comprehensive, multi-layered protective network against oxidation, providing more comprehensive and long-lasting protection for cells against free radical damage.
Key Advantages of 98% Purity Hydroxytyrosol
(I) Enhanced Bioavailability Due to High Purity
In the extraction process of hydroxytyrosol, supercritical CO₂ extraction and high-performance liquid chromatography (HPLC) purification technologies play a crucial role, acting as the “behind-the-scenes heroes” that enable the hydroxytyrosol powder to reach a purity of over 98%. Supercritical CO₂ extraction technology utilizes the special solubility effect of CO₂ in its supercritical state to perform extraction under high pressure and low temperature. This method is not only suitable for the extraction of volatile substances but also selectively extracts non-volatile, high-boiling-point substances. Furthermore, the product is free of solvent residue, thus maximizing the preservation of hydroxytyrosol’s natural activity. High-performance liquid chromatography (HPLC) purification technology acts like a precise “filter,” further removing impurities and significantly increasing the purity of hydroxytyrosol.
This high purity directly leads to a significant improvement in bioavailability. Hydroxytyrosol itself has lipophilic properties, which increases its absorption rate in the intestines by 30% compared to some other antioxidants. It acts like a nutrient that is easily “recognized” and absorbed by the intestines, allowing it to smoothly enter the human circulatory system. Even more noteworthy is that, through advanced nano-encapsulation technology, hydroxytyrosol can cross the blood-brain barrier. The blood-brain barrier acts like a “fortified defense line” for the brain, preventing many substances from entering. However, nano-encapsulation technology encapsulates hydroxytyrosol, allowing it to successfully pass through this barrier and directly act on the central nervous system. Relevant studies show that this high-purity hydroxytyrosol is 50% more effective in protecting against neuronal oxidative damage than ordinary extracts, demonstrating immense potential in protecting brain neurons and preventing neurodegenerative diseases.
(II) Multi-Dimensional Health Protection Mechanism
1. Cellular Anti-Aging: At the cellular level, hydroxytyrosol exhibits powerful anti-aging capabilities, primarily by inhibiting the activity of matrix metalloproteinases (MMPs). MMPs act like “destroyers,” breaking down collagen, which is a key substance for maintaining skin elasticity and firmness. 1. **Skin Anti-Aging:** Hydroxytyrosol inhibits the activity of MMPs, effectively “restraining” these “destroyers” and reducing collagen degradation. Simultaneously, it promotes the synthesis of type I collagen by fibroblasts. Fibroblasts act like “factories” producing collagen, and hydroxytyrosol stimulates these “factories” to increase production. Clinical trials are an important standard for evaluating effectiveness. Clinical studies have shown that supplementing with high-purity hydroxytyrosol for 8 consecutive weeks can increase skin elasticity by 28% and reduce wrinkle depth by 15%, offering new hope in the fight against aging.
2. Cardiovascular Protection: Cardiovascular health is a crucial indicator of overall health, and hydroxytyrosol plays a significant role in this area. It regulates lipid metabolism and reduces the susceptibility of low-density lipoprotein (LDL) to oxidation. Oxidized LDL is like “garbage” in the blood vessels, easily accumulating on the vessel walls and leading to cardiovascular diseases such as atherosclerosis. Hydroxytyrosol reduces this oxidation, lowering the risk of cardiovascular disease. Furthermore, hydroxytyrosol can dilate vascular smooth muscle, acting like a “relaxing massage” for blood vessels, causing vasodilation and thus lowering systolic blood pressure by 10-15 mmHg. This is especially beneficial for individuals with high-sugar and high-fat diets, whose vascular endothelium is more susceptible to damage. Hydroxytyrosol provides significant protection for their vascular endothelium, offering strong support for their cardiovascular health.
3. Immune Regulation and Anti-inflammation: Hydroxytyrosol also demonstrates excellent performance in immune regulation and anti-inflammation. It inhibits the NF-κB inflammatory pathway. NF-κB is a key regulatory factor in inflammatory responses, acting like the “commander” of the inflammatory response. By inhibiting its activity, hydroxytyrosol effectively disarms this “commander,” reducing the release of pro-inflammatory factors such as TNF-α and IL-6. In chronic inflammation models such as arthritis and colitis, hydroxytyrosol’s anti-inflammatory efficiency reaches 40%-60%, indicating its important role in alleviating chronic inflammation and enhancing immunity, offering new treatment approaches and hope for patients with chronic inflammatory diseases.
(III) Safety and Quality Standards
In terms of safety and quality standards, 98% pure hydroxytyrosol powder is subject to strict control. Precise testing using HPLC-MS/MS ensures that the product is free from harmful substances such as pesticide residues, plasticizers, and heavy metals. This is like a comprehensive “health check” for the product, guaranteeing its safety. Furthermore, it has passed both the US FDA GRAS certification and the EU EFSA safety assessment. These certifications and assessments are like “safety passes” issued by international authoritative organizations, proving that the safety of hydroxytyrosol is internationally recognized.
Regarding content standards, the 98% purity ensures that each gram of powder contains ≥980mg of hydroxytyrosol, guaranteeing the product’s effectiveness. In terms of dosage, a daily supplement of 10-20mg is recommended to achieve significant antioxidant effects. Research has also shown that its LD50 > 5g/kg, classifying it as practically non-toxic. This means that within the normal intake range, it will not pose any toxic risk to the human body, allowing consumers to use it with confidence.
Innovative Application Scenarios in Antioxidant Supplements
(I) The Golden Formula of Functional Health Products
In the field of functional health products, 98% hydroxytyrosol powder has become a core ingredient in many innovative formulas, demonstrating a powerful synergistic effect. Taking compound antioxidant capsules as an example, the scientific formulation of 98% hydroxytyrosol with astaxanthin, vitamin E, glutathione, and other antioxidants can form a comprehensive, multi-layered antioxidant system.
In a classic formula, each capsule contains 20mg of hydroxytyrosol, 8mg of astaxanthin, and 35mg of vitamin E. Astaxanthin is a potent antioxidant derived from algae, possessing a unique molecular structure that efficiently captures free radicals, especially excelling in combating singlet oxygen. Vitamin E, a fat-soluble vitamin widely found in various plant oils and nuts, protects cell membranes from oxidative damage and maintains normal cell function. Glutathione, as an endogenous antioxidant, plays a crucial role in cellular antioxidant processes, participating in redox reactions and maintaining intracellular redox balance.
When these components are combined with 98% hydroxytyrosol, remarkable effects are produced. Related studies have shown that this compound formula can enhance cellular antioxidant capacity by up to 60%, meaning cells can better resist free radical attacks and maintain a healthy state. In a four-week clinical observation, a group of subjects underwent supplementation with this compound formula. The results showed that the subjects’ serum MDA (malondialdehyde) levels decreased by 35%. MDA is a marker of oxidative damage, and its decrease indicates an effective reduction in oxidative stress. Simultaneously, the subjects’ SOD (superoxide dismutase) activity increased by 22%. SOD is an important endogenous antioxidant enzyme, and its enhanced activity signifies a strengthening of the body’s own antioxidant defense system.
(II) Precision-Targeted Functional Food Development
1. Sports Nutrition: In the field of sports nutrition, 98% hydroxytyrosol powder has shown great application potential. With increasing health awareness and the rise of sports enthusiasm, more and more people are participating in various high-intensity sports, such as marathons and strength training. However, these high-intensity exercises often lead to the production of a large number of free radicals in the body, triggering oxidative stress and resulting in problems such as muscle soreness, increased fatigue, and prolonged post-exercise recovery time.
98% hydroxytyrosol powder, due to its powerful antioxidant capacity, has become an ideal choice for solving these problems. Adding it to sports drinks or energy gels can effectively alleviate oxidative stress caused by high-intensity exercise. It acts like a “free radical scavenger,” quickly capturing and eliminating free radicals generated during exercise, reducing damage to muscle cells. Studies have shown that after consuming sports drinks containing hydroxytyrosol, the free radical content in muscle tissue is significantly reduced, and oxidative damage to muscle cells is effectively inhibited.
At the same time, hydroxytyrosol can also accelerate post-exercise recovery. It can promote the repair and regeneration of muscle cells, improving muscle strength and endurance. For marathon runners, consuming sports drinks or energy gels containing hydroxytyrosol before and after a race can reduce muscle soreness, shorten recovery time, and allow them to return to peak condition more quickly, preparing them for the next training session or competition. For strength trainers, hydroxytyrosol can help reduce muscle fatigue, improve training effectiveness, and promote muscle growth and repair.
2. Health Foods for Middle-Aged and Elderly: 98% hydroxytyrosol powder also has unique applications in the field of health foods for middle-aged and elderly people. With age, the physical functions of middle-aged and elderly people gradually decline, and joint cartilage and bone tissue are more susceptible to oxidative stress and inflammation, leading to problems such as osteoporosis and joint inflammation.
Combining 98% hydroxytyrosol with ingredients such as glucosamine and calcium supplements can develop health foods for middle-aged and elderly people with multiple benefits. Glucosamine is a natural amino monosaccharide and an important component of joint cartilage, promoting the synthesis and repair of chondrocytes and maintaining the health of joint cartilage; calcium supplements are an important source of calcium, which plays a crucial role in maintaining bone strength and density.
98% hydroxytyrosol plays a crucial synergistic role in this formula. It not only enhances the antioxidant capacity of bones and reduces free radical damage to bone tissue, but also inhibits inflammatory responses and prevents the synergistic occurrence of osteoporosis and joint inflammation. Clinical studies have shown that long-term consumption of health foods containing this compound ingredient can significantly improve bone density in middle-aged and elderly individuals, alleviate joint pain and inflammation symptoms, and improve their quality of life.
(III) Active Ingredients in Cosmetics and Personal Care
In the cosmetics and personal care field, 98% hydroxytyrosol powder, with its superior antioxidant and skin-care effects, has become a core ingredient in many high-end anti-aging skincare products. As people’s attention to skin health and beauty continues to increase, the demand for anti-aging skincare products is also growing. The emergence of 98% hydroxytyrosol powder has brought a new breakthrough to the skincare industry.
As a core ingredient in high-end anti-aging skincare products, hydroxytyrosol powder can be formulated into various dosage forms, such as serums and masks. In serums, high concentrations of hydroxytyrosol can quickly penetrate to the deeper layers of the skin, exerting its powerful antioxidant and repairing effects. It can inhibit the activity of tyrosinase, a key enzyme in melanin synthesis. Inhibiting its activity reduces melanin production, thus achieving a whitening and spot-fading effect. Studies have shown that hydroxytyrosol can inhibit tyrosinase activity by up to 30%, meaning it can effectively reduce the formation of age spots, making the skin whiter and brighter.
Simultaneously, hydroxytyrosol can increase the moisture content of the stratum corneum, improving dry skin. It can promote skin cell metabolism, enhance the skin’s moisturizing ability, and keep the skin hydrated and plump. Experimental data shows that after using a serum containing hydroxytyrosol for four weeks, the moisture content of the stratum corneum of the subjects increased by 25%, and the dryness and roughness of the skin were significantly improved.
For face masks, the addition of hydroxytyrosol powder can provide intensive care to the skin in a short time. The occlusive nature of the mask promotes the absorption of hydroxytyrosol by the skin, allowing it to work better. After using a mask containing hydroxytyrosol, the skin can quickly replenish moisture and nutrients, becoming firmer and more elastic, and dull skin tone can also be effectively improved. It is especially suitable for mature skin and sun-damaged skin. It can help repair damaged skin cells, enhance the skin’s self-repair ability, and delay the aging process of the skin.
Controlling the Entire Supply Chain from Raw Materials to Finished Products
Controlling the Entire Supply Chain from Raw Materials to Finished Products(I) Green Extraction Process Analysis
In producing 98% hydroxytyrosol powder, we employ low-temperature ultrasonic-assisted extraction combined with chromatographic purification technology. This technology acts like a meticulously designed “magic process,” precisely extracting high-purity hydroxytyrosol from olive raw materials while preserving its activity to the maximum extent.
In the raw material selection stage, we are like a group of discerning “gourmets,” selecting only ripe olive leaves from the Mediterranean region. These olive leaves grow in the sunny, climatically suitable Mediterranean region, and their unique natural environment endows them with rich nutrients. Moreover, only olive leaves with a hydroxytyrosol content ≥2% are qualified to enter the next stage of the production process. This sets a strict “entry threshold” for olive leaves, ensuring the high quality of the raw materials.
In the extraction process, we adopt a gentle yet efficient method. Using a 70% ethanol aqueous solution as the extraction solvent, this solvent acts like a “gentle transporter,” extracting hydroxytyrosol from the olive leaves without damaging its structure. Ultrasonic extraction is performed at a low temperature of 40℃. Ultrasound acts like an invisible “energy wave,” accelerating the release of hydroxytyrosol from olive leaf cells and improving extraction efficiency. Furthermore, we perform three extractions, much like exploring a treasure trove multiple times, to extract as much hydroxytyrosol as possible from the olive leaves. After extraction, the three extracts are combined and then passed through a macroporous resin column for preliminary impurity removal. The macroporous resin column acts like a “precision filter,” effectively removing pigments and sugar impurities from the extract, resulting in a purer extract.
Next comes the purification stage, a process that pursues ultimate purity. HPLC preparative columns are used to separate the target component. HPLC preparative columns act like a “super-precise filter,” accurately separating hydroxytyrosol from other impurities to obtain high-purity hydroxytyrosol. Finally, hydroxytyrosol is spray-dried to produce a free-flowing white powder. Spray drying is like a magical “rain,” transforming liquid hydroxytyrosol into a fine powder with a moisture content of <5% and a particle size of ≤80 mesh. This makes it more convenient for subsequent applications and allows it to better exert its efficacy.
(II) Quality Control and Standardization
To ensure that every batch of 98% hydroxytyrosol powder meets high-quality standards, we have established a strict three-tiered quality control system. This system acts like a tight “quality protection net,” comprehensively guaranteeing product quality from raw materials to finished products.
In the raw material testing stage, we use high-precision HPLC instruments, like a “precise ruler,” to determine the hydroxytyrosol content, ensuring raw material purity ≥98%. Simultaneously, we rigorously test for solvent residue, requiring it to be <0.05%. This is to ensure the safety of the raw materials, allowing consumers to use our products with confidence.
During the production process, our production environment strictly complies with ISO22000 standards. This is like putting a “quality and safety cap” on the production workshop, ensuring the standardization and safety of the entire production process. Each batch of intermediates undergoes microbial and heavy metal testing. Microbial testing primarily focuses on total bacterial count, requiring a total bacterial count <100 CFU/g to prevent microbial contamination and ensure product hygiene. Heavy metal testing focuses on lead and arsenic content, requiring lead <1 ppm and arsenic <0.5 ppm to avoid harm to human health and protect consumers’ health.
After production, the product undergoes a crucial final product release test. We use DSC (Differential Scanning Calorimetry) to verify the product’s thermal stability. DSC acts as a “thermal stability detector,” accurately detecting changes in the product’s thermal properties at different temperatures. Simultaneously, we conduct accelerated aging tests, placing the product in a 60℃/90% RH environment for 14 days and then testing its activity retention rate, requiring an activity retention rate >95%. This simulates the product’s actual storage and use, ensuring the product maintains good activity and efficacy over a long period.
Market Prospects and Industry Trends
(I) Upgrading Opportunities in the Antioxidant Market
Globally, the antioxidant health industry is booming at a compound annual growth rate of 8%, reflecting people’s increasing emphasis on health and antioxidant products.

In the market, the purity of ordinary olive extract is typically between 10% and 40%, while our 98% hydroxytyrosol powder has a significant advantage. These advantages constitute our core barriers to differentiation in the market.
From the perspective of efficacy claims, the high purity of 98% means a higher content of active ingredients, allowing for a clearer and more effective claim to the product’s efficacy. Consumers often prefer products with clearly defined efficacy, and high-purity hydroxytyrosol powder can meet their expectations for product effects. In terms of formula simplification, due to its high purity, a smaller amount can be used in product formulations to achieve the same efficacy. This makes the formula more streamlined, reduces the addition of other unnecessary ingredients, lowers product complexity, and improves product safety.
Regarding end-product premium, high-purity hydroxytyrosol powder can enhance the quality and value of end products, thereby allowing for higher market prices. Companies can target the high-end market through a strategy of “high-purity raw materials + precise scenario-based formulation.” For example, developing “antioxidant emergency capsules” for those who stay up late, as staying up late leads to the production of a large number of free radicals, the high-purity hydroxytyrosol in these capsules can quickly eliminate free radicals and alleviate fatigue and oxidative damage caused by staying up late; and launching “repairing dietary supplements” for those recovering from cosmetic procedures, as the skin needs repair and anti-oxidation after cosmetic procedures, the antioxidant and repair functions of hydroxytyrosol can help the skin recover faster and reduce inflammation and pigmentation.
(III) Compliance and Innovative R&D Directions
In the application and development of hydroxytyrosol, compliance and innovative R&D are two important directions. Staying abreast of regulatory developments in various countries is crucial to ensuring the legal sale and use of products in the market. In China, the application for new food ingredients must adhere to strict procedures and standards. Companies need to provide sufficient safety and functional data in accordance with relevant regulations to obtain approval. Similarly, health claim filing with the US FDA is equally important; companies need to ensure that their product’s health claims comply with FDA regulations and avoid false advertising.
Developing sustained-release formulations in conjunction with gut microbiota research is an innovative research direction. Gut microbiota has a significant impact on human health, and the absorption and utilization of many nutrients are closely related to it. Developing sustained-release formulations allows hydroxytyrosol to be released slowly in the intestines, prolonging its duration of action and improving bioavailability. Moreover, this formulation can better protect hydroxytyrosol, preventing its degradation in environments such as stomach acid.
Developing synergistic products by combining hydroxytyrosol with probiotics and polyphenols is also a promising direction. Probiotics can regulate gut microbiota and improve gut health; when combined with hydroxytyrosol, they can enhance overall health. Polyphenols possess a variety of bioactivities, and when combined with hydroxytyrosol, they can exert a synergistic effect, enhancing antioxidant and anti-inflammatory efficacy. Through these innovative research and developments, hydroxytyrosol is being upgraded from a single ingredient to a systemic antioxidant solution, providing consumers with more comprehensive and efficient health products.
Hydroxytyrosol powder (98%), with its superior antioxidant activity and safety, is becoming a revolutionary ingredient in functional foods, health supplements, and cosmetics. Through scientific formulation design and precise application scenarios, this natural olive extract will continue to empower the health industry, providing consumers with efficient and safe solutions to oxidative stress.
