Sparta® Medicinal Wild Olive Oil® Reports World-Record 5,134 mg/kg Polyphenol Concentration
Sparta® Medicinal Wild Olive Oil®, an officially licensed Medicinal Olive Oil® since 2018, has announced a record-setting polyphenol concentration of 5,134 mg/kg for its 2026–2027 harvest. According to the company, the result represents a new world record for polyphenol concentration in olive oil and has been independently verified by an International Olive Council laboratory.
The record concentration is reported for Sparta® Wild Olive Oil Reserve, a product sourced exclusively from an ancient wild olive forest in Lykovouni-Mavromichaleika, Laconia, Sparta, Greece. The company says the oil contains more than 20,000 mg/kg of total bioactive compounds, including polyphenols, oleocanthal, squalene, sterols and vitamin E.
Sparta® describes its wild olive oil as a highly specialized product built around the preservation of naturally occurring compounds in wild olive fruit. The company says its production approach combines controlled harvesting, an integrated internal production process and a non-intervention protocol intended to protect the characteristics of the raw material from the estate through processing and bottling.
Record Polyphenol Concentration
Polyphenols are naturally occurring compounds found in olives and olive oil and are widely studied for their antioxidant and other biological properties. The concentration of these compounds can vary significantly depending on factors such as olive variety, growing conditions, harvest timing, processing techniques and storage.
For the 2026–2027 harvest, Sparta® reports that its Wild Olive Oil Reserve reached 5,134 mg/kg of total polyphenols. The company says the measurement was certified through an International Olive Council laboratory, providing independent analytical verification of the reported concentration.
The company further states that the molecular profile of its oil has been examined using advanced analytical technologies, including High-Performance Liquid Chromatography (HPLC), Liquid Chromatography-Mass Spectrometry (LC-MS), and Nuclear Magnetic Resonance (NMR).
According to Sparta®, testing and validation have involved institutions and organizations including the Pharmacy Faculty of the University of Athens, the University of Córdoba, the University of Crete, the International Olive Council and TÜV AUSTRIA.
The company also cites recognition from the Pharmacy Faculty of the University of Athens, which has described the wild olive source associated with Sparta® as “the healthiest and highest polyphenolic olive in the world for years.” Such statements are presented by Sparta® as part of its scientific and institutional history surrounding the product.
Sourced From an Ancient Wild Olive Forest
A defining feature of Sparta® Medicinal Wild Olive Oil® is its raw material. Rather than sourcing olives from conventional agricultural plantations, the company says its oil is produced exclusively from olives harvested from a privately certified estate containing an ancient Wild Olive Forest in Lykovouni-Mavromichaleika, Laconia, Sparta.
The company considers the natural environment of the estate an important component of its production philosophy. The wild olive trees grow within an ecosystem that Sparta® says allows the fruit to develop under natural conditions without conventional agricultural intervention.
Sparta® states that its production philosophy is based on a world-pioneering non-intervention protocol. The objective, according to the company, is to maintain the natural characteristics of the wild olive fruit while minimizing external influences throughout cultivation, harvesting and processing.
The production unit operates through what Sparta® describes as a fully integrated internal process. This approach is designed to provide greater control over the journey of the raw material and finished oil while maintaining the company’s quality and traceability standards.
Scientific Testing and Analytical Validation
The company places considerable emphasis on laboratory analysis and independent verification. Sparta® says the 5,134 mg/kg polyphenol measurement was certified by an International Olive Council laboratory.
In addition to polyphenol analysis, the company says its products have undergone testing involving multiple analytical methodologies. HPLC, LC-MS and NMR are commonly used analytical techniques capable of identifying and quantifying chemical compounds and characterizing complex molecular profiles.
According to Sparta®, its testing program examines the composition of the oil beyond polyphenols, including compounds such as oleocanthal, squalene, sterols and vitamin E. The company reports a total concentration of more than 20,000 mg/kg of bioactive compounds.
The company also says its products have been tested for contaminants and unwanted substances. Its published claims include testing for microplastics, heavy metals, fertilizers, chemicals, pesticides and atmospheric oxides.
Sparta® says its bottling and storage standards further support product protection, with the company using glass or stainless-steel containers rather than conventional plastic packaging for its oil.
Sustainability and Carbon Management
Environmental considerations are another component of the company’s estate-based production model.
Sparta® says the estate has been certified by TÜV NORD and describes it as a negative-carbon estate. According to the company, the estate naturally absorbs approximately 431 tons of CO₂ annually.
The company presents this carbon-absorption capacity as part of its broader environmental philosophy, linking the preservation of the ancient wild olive forest with biodiversity, natural cultivation and carbon management.
By maintaining the estate as a natural wild olive environment rather than converting it into a conventional intensive agricultural operation, Sparta® says it seeks to preserve the character of the landscape while producing a specialized olive oil.
Medicinal Olive Oil® Designation
Sparta® Medicinal Wild Olive Oil® has held an officially licensed Medicinal Olive Oil® designation since 2018, according to the company.
The designation forms part of Sparta®’s long-term positioning of its wild olive oil as a specialized product with a focus on exceptionally high concentrations of naturally occurring compounds.
The company says its products have attracted interest from health professionals, hospitals, clinics, physiotherapy centers, rehabilitation institutes and professional athletes over the past nine years. Sparta® cites this adoption as part of its experience with the use of its wild-harvest olive oil in wellness-oriented settings.
However, the company distinguishes these applications from conventional culinary olive oil positioning, emphasizing the oil’s unusually high concentration of polyphenols and other bioactive compounds.
Focus on Polyphenol-Rich Olive Oil
Interest in high-polyphenol olive oil has grown alongside broader scientific and consumer attention toward the naturally occurring compounds found in extra virgin and other specialty olive oils.
Polyphenols are a diverse group of plant compounds. In olive oil, researchers have studied individual compounds and their potential biological effects, including antioxidant and anti-inflammatory mechanisms. However, the presence of a compound or a high concentration of a compound does not by itself establish that an olive oil can prevent, treat or manage a specific medical condition.
Sparta®’s CEO, Dimitris Sakkas, points to the reported 5,134 mg/kg concentration as a significant milestone for the company.
“The +5,000 mg/kg polyphenol wild olive oil is a milestone,” Sakkas said. “The long-standing adoption of our wild harvest by hospitals, clinics, physiotherapy centers, rehabilitation institutes, health professionals, and world-class athletes over the past nine years reflects what we already know through experience, ancestral knowledge, customer feedback, and scientific research.”
Sakkas added that the company believes exceptionally bioactive, polyphenol-rich wild olive oil may have potential applications in areas including longevity, biohacking, prevention and long-term wellness, as well as supporting the management of various health conditions.
Those potential applications remain an area of interest for further scientific investigation and should be distinguished from established medical treatment claims.
A Distinctive Approach to Olive Oil Production
The latest announcement positions Sparta® Wild Olive Oil Reserve around three central characteristics: wild-origin raw material, unusually high polyphenol concentration and extensive analytical testing.
The company says its approach begins with the ancient wild olive forest in Laconia and continues through a controlled internal production process. Independent laboratory testing is then used to document the chemical composition of the resulting oil.
The reported 5,134 mg/kg result provides a specific analytical benchmark for the 2026–2027 harvest. Because olive oil composition can vary from harvest to harvest, environmental conditions, olive maturity and processing methods remain important factors in determining final composition.
Sparta® says its objective is to preserve the distinctive molecular profile of its wild olives while maintaining strict controls over production and storage.
