                                According to the Georgetown Olive Oil Co., a specialized ultra-high phenolic olive oil made from Kalamata olives has been lab-tested with an astonishing polyphenol count of 1799 mg/kg. This incredible concentration is possible through specific harvesting and processing techniques, but several olive varieties are known globally for their naturally high polyphenol levels.
