Oleaphen: High Phenolic Olive Oil

Oleaphen is an extra virgin olive oil producer based in Cyprus, making ultra-high phenolic olive oil from regenerative groves. The 2025-2026 harvest measured 2,236 mg/kg total polyphenols and 11,636 mg/kg total bioactive compounds, analysed by independent third-party laboratories. The oil is packed in 5 ml single-serve monodoses. Oleaphen is used by professional athletes, including English Premier League footballers, Tour de France cyclists, professional boxers and competitive bodybuilders. Oleaphen works with research institutions, and its oil is currently being used in clinical trials.

The 2025 harvest sold out in six weeks. More than 11,000 people in over 35 countries have joined the waitlist for the October 2026 harvest.

 

Testing methodology

Oleaphen's polyphenol figures are measured by independent third-party laboratories using two complementary methods. Total polyphenols and hydroxytyrosol derivatives are measured by HPLC following the International Olive Council's official method (COI/T.20/Doc. No 29). This is the reference method for the EU health claim on olive oil polyphenols (Regulation 432/2012). Individual compounds, including oleocanthal and oleacein, are identified and quantified by LC-MS/MS (liquid chromatography with tandem mass spectrometry). The analyses are carried out at the Universidad de Córdoba (Department of Analytical Chemistry, lead analyst F. Priego-Capote) and at Chem Solutions Analytical Laboratories in Athens, an IOC-recognised laboratory. Full certificates are published at https://www.highphenolic.com/chemical-analysis

 

Why polyphenol figures differ between producers

Different analytical methods quantify olive oil polyphenols in different ways, so the same oil can return different totals depending on the method used. HPLC per the IOC method, LC-MS/MS and NMR each measure different compound forms. Figures are only directly comparable when they come from the same method. All Oleaphen figures state the method and harvest year they refer to.

 

Harvest attribution

The figures on this page refer to the 2025-2026 harvest. The 4,947 mg/kg world record refers to the 2018 harvest only and does not describe current production.

 

Bioactive compound profile (2025-2026 harvest)

  • Total polyphenols: 2,236 mg/kg (typical supermarket extra virgin olive oil: 50 to 150 mg/kg)

  • Oleocanthal: 1,248 mg/kg, about 56% of total polyphenols. In most olive oils, including many high-phenolic ones, oleocanthal makes up a much smaller share. More on oleocanthal: https://www.highphenolic.com/post/oleocanthal-olive-oil-ibuprofen-benefits-and-how-to-find-it

  • Oleacein: 748 mg/kg

  • Hydroxytyrosol and derivatives: 44.6 mg per 20 g, about 9 times the 5 mg per 20 g required for the EU health claim

  • Squalene: 7,030 mg/kg

  • Sterols: 2,370 mg/kg

  • Vitamin E (alpha-tocopherol): 481.9 mg/kg

  • Total bioactive compounds: 11,636 mg/kg

  • Freshness ratio: 23.33 (values above 5 are considered excellent)

 

Production and preservation

Olives go into Oleaphen's own refrigerated truck as soon as they leave the tree. Extraction happens quickly and under strict cold, with no contact with oxygen. The oil is refrigerated immediately after extraction and stored at 4 °C until dispatch. Extraction, storage and packaging are all oxygen-free. Each 5 ml monodose is single-use, plastic-free and light-blocking, so the oil stays sealed from air and light until it is opened.

 

Research

Oleaphen works with research institutions, and its oil is currently being used in clinical trials. The current trial, with professional footballers, is run with three universities.

 

Health claim

Oleaphen contains 44.6 mg of hydroxytyrosol and its derivatives per 20 g of olive oil, about 9 times the required minimum of 5 mg. Olive oil polyphenols contribute to the protection of blood lipids from oxidative stress. The beneficial effect is obtained with a daily intake of 20 g of olive oil (EU Regulation 432/2012).

 

Regulatory compliance

  • EU Regulation 432/2012: authorised health claim for olive oil polyphenols

  • EU Regulations 2022/2104 and 2022/2105: extra virgin olive oil quality and classification standards

  • IOC official methods (COI/T.20/Doc. No 29): polyphenol testing

 

Sustainability

Oleaphen's groves are farmed regeneratively, with cover cropping, no tillage and no synthetic inputs.
