Polyphenol Rich Olive Oil

What Is Polyphenol-Rich Olive Oil?

High phenolic olive oils are olive oils that contain a high percentage of phenolic compounds and are directly related to the health benefits of olive oil. This oil contains at least 30 phenolic compounds, the principal ones being oleuropein, hydroxytyrosol, and oleic acid, compounds known to be strong antioxidants and radical scavengers.

Polyphenol-rich olive oils have been found to:

  • Boost the immune system – A 2019 study reveals that polyphenols from three different olive oil varieties have an inhibitory effect against several bacterial strains, effectively boosting the immune system.
  • Promotes heart health –  Polyphenols help manage blood pressure levels and keep your blood vessels healthy and flexible, promoting good blood circulation. They also help reduce chronic inflammation, which increases heart disease risk.
  • Prevent many types of cancer – Polyphenol-rich olive oils contain oleocanthal, a compound that kills cancer cells with their own enzymes without harming the healthy ones.
  • Helps manage effects of diabetes – Polyphenols may influence blood glucose at different levels and may also help control and prevent diabetes complications. Studies have also linked extra virgin olive oil to higher levels of insulin, making it beneficial to people with type 2 diabetes.
  • Prevent cognitive decline – Recent studies show that consuming polyphenolic-rich extra-virgin olive oil protects memory and learning ability and reduces the buildup of proteins in the brain, which is the cause of Alzheimer’s disease.
  • Promotes better mental health – Aside from improving cognitive function, high concentrations of polyphenols found in olive oil can positively impact one’s mental health. A Spanish study found that those who frequently ate a Mediterranean diet (which involves a lot of olive oil) are 30% less likely to develop depression.

Can I cook with high polyphenol olive oil?

Aside from its health benefits, olive oils rich in polyphenol have a unique flavor from ordinary olive oils. Olive oils of this type commonly have a pronounced robust, bitter taste and a hot peppery finish, though some oils sourced from other types of olives, such as the koroneiki olives, pack a greener, fruitier flavor. 

While most people drink this type of olive oil daily, with its flavor considered, polyphenol-rich olive oils can add flavor and depth to any dish you choose, whether you cook with it or drizzle it as a finishing touch. Restaurants often add this to dishes to give them more flavor and depth.

4 Best High Polyphenol Olive Oil Brands – The List

1. Polyphenol-Rich Olive Oil – Gundry MD

Gundry Polyphenol Rich Olive Oil

Polyphenol count per kg: 14 mg of hydroxytyrosol per tablespoon

Harvest date: Not specified

Country of origin: Morocco

Gundry MD’s Polyphenol-Rich Olive Oil is exclusively sourced from olive trees grown in Morocco’s harsh desert environment, which has the ideal climate for olive cultivation – mild winters and warm, dry summers, which make them produce extra polyphenols to protect themselves; this gives their olive oil up to 30x more hydroxytyrosol polyphenols, making it superior compared to most brands.

What does that give you? Since hydroxytyrosol is a polyphenol that neutralizes free radicals, it gives you more protection from toxins that can make you feel weak and tired. It also provides added protection for the immune and cardiovascular systems and reduces the risk of neurodegenerative diseases like Alzheimer’s and other memory disorders, among many other benefits.

2. AWAKE Extra Virgin Olive Oil – Brightland

Polyphenol count per kg: 592 mg/kg

Harvest date:  November 2021

Country of origin: California, USA

Brightland’s AWAKE Extra Virgin Olive Oil lives by the saying, “the more, the better.” It has a polyphenol count of 592 mg/kg (compared to most oil brands containing only an average of 80-150 mg/kg). The higher the polyphenol count, the more the olive oil has disease-fighting antioxidants, antimicrobial, anticancer, and anti-inflammatory properties.

AWAKE uses arbequina olives which, aside from having a high amount of polyphenols and antioxidants, also has a high percentage of oleic acid, which can help increase good cholesterol levels. The olives are sourced from small family farms on California’s Central Coast and are cold-pressed shortly after being harvested for maximum freshness and flavor.

This oil’s smoky, peppery flavor makes an excellent addition to soups, stews, pasta, roasted meat/vegetables, and bread. You won’t have to worry about the heat requirement for dishes since this olive oil has a smoke point of 410°F (compared to regular brands having about  374-405°F), making it an ideal choice for most cooking methods

Regarding its packaging, each glass bottle is UV-coated to preserve the olive oil from damaging light so that you can be assured of its freshness and integrity. 

Pros & Cons


  • High polyphenolic content compared to most brands
  • High smoke point
  • Can be used for various cooking methods
  • Undergoes quality testing
  • Female-owned business
  • Well-packaged
  • Bottles are UV-coated to maintain freshness

How can polyphenol-rich olive oil be consumed?

Polyphenol-rich olive oil is normally added as an ingredient to various dishes and is used as a finishing oil to add more flavor and depth. But you can also take a spoonful daily to reap its health benefits.

How much polyphenol-rich olive oil should I consume daily?

Experts recommend that taking 20 g (4 teaspoons) of high-polyphenol olive oil daily is enough to benefit heart health.

How is high polyphenol olive oil certified?

Olive oil samples are usually sent to laboratories for analysis to determine the oil’s phenolic profile. For an olive oil brand to be considered high in polyphenols, it should contain a minimum of 250 mg of polyphenols per kilogram.

Can you take too much high polyphenol olive oil?

While polyphenol-rich olive oil contains healthy mono- and polyunsaturated fatty acids, taking too much of it can result in weight gain, and drinking the oil purely on its own may not yield the same benefits as it does when consuming it with food.

Storing Your Polyphenolic-Rich Olive Oil

Already picked the right olive oil for you? Here’s how you can store it to maintain its nutritional properties:

  • Keep the olive oil bottle away from heat and light to prevent it from losing its properties and freshness. Always store it away in a cool, dark cupboard or a darker corner of your shelf. 
  • Once you’ve opened your bottle of olive oil, make sure to consume it within a few months.


Polyphenol-rich olive oil has been the subject of many scientific studies and has been praised for its power in promoting heart health, brain health, and immune system function, and its antioxidant, anti-inflammatory, and anticancer properties.

Cooking with polyphenol-rich olive oil can also create a difference even with ordinary dishes due to its distinct flavor blend. It’s also more practical for cooking because it usually has a high smoke point, helping it retain its polyphenolic content and even increase the nutrient content of the cooked food.
