Could Olive Oil Help Fight COVID-19 Symptoms?

updated May 2022

Here’s Why People are Adding Extra-Virgin Olive Oil to Their Pandemic Diets

Few people saw COVID-19 coming, and the pandemic took most of us by surprise – shattering the very fabric of life as we (thought) we knew it.

Millions of people worldwide have lost their lives at the hands of this novel virus, many of whom suffered from comorbidities or followed poor diets during their lifetimes before succumbing to the devastating infection.

While the coronavirus affects everyone in different ways, the World Health Organization (WHO) as well as the UK’s National Health Service (NHS) have urged world citizens to follow a regular exercise routine and eat as healthily as possible to help the body cope better with potential symptoms should COVID infection occur.

Among the long list of healthy foods recommended by these organizations during COVID-19 is olive oil – which is an unsaturated fat as opposed to its saturated counterpart that you might find in things like meat, cheese, butter, lard, and ghee.

While we’ve all heard that olive oil is good for you, it’s not something you should just walk into the store and buy.

Countless studies highlight time and time again the importance of buying Extra-Virgin Olive Oil (EVOO) that is naturally high in polyphenols.

These compounds are what could, according to new evidence, help control the adverse effects of COVID-19 in the body.


  • How can high-polyphenol olive oil help reduce the symptoms of COVID-19?
  • Which studies show the possibility that oleuropein prevents COVID-19?
  • How and why do olive oil’s phenolic compounds – like Oleanolic Acid and/or Oleocanthal – appear to fight coronavirus?
  • Why is high-phenolic olive oil the best source of natural polyphenols?
  • What is the highest quality EVOO on the market?
  • Why does olive oil need to be cold-pressed?
  • What is medicinal grade olive oil?
  • Why is HYPERELEON the best choice for high-phenolic medicinal grade olive oil?

So, without further ado, let’s dive right in.

How Can High-Polyphenol Olive Oil Help Reduce the Symptoms οf COVID-19?

In a nutshell, EVOO – a staple in the Mediterranean diet – has low cytokine levels.

Keeping your cytokine levels in check could be a saving grace in the fight against COVID-19 by potentially reducing the severity of your illness and its related symptoms.

Cytokines play a key role in immune system support, but too many cytokines can cause what experts name a “cytokine storm” – otherwise known as hypercytokinemia. This means that the immune system overreacts to any foreign invaders, which can cause much more severe illness or even death in COVID-19 patients.

These cytokine storms have been found to reduce how much oxygen is in the blood while causing fluid to accumulate in the lungs.

This can make breathing a challenge and raise the chances of the patient experiencing even more adverse side effects.

Researchers have found that olive oil consumption could play a role in the prevention of adverse COVID-19 symptoms and even death. It all boils down to having healthy immune system, something olive oil has been treasured for contributing to for centuries.

High-phenolic olive oil is also high in something called oleuropein, which Ahmad Alkhatib – researcher at the Teeside University Center for Public Health – hails for its potential to encourage antiviral activity in the body.

This has already been explored in the respiratory syncytial virus, a common infection that affects the upper respiratory tract, and researchers like Ahmad have high hopes for high-phenolic olive oils in the fight against COVID-19 too.

In Summary

  • Extra virgin olive oil could keep your cytokine levels in check.
  • “Cytokine storms” reduce oxygen in the blood, making it harder to breathe.
  • Olive oil could play a role in the prevention of adverse COVID symptoms.
  • A strong immune system is often the key to COVID-19 survival.

Which Studies Show the Possibility That Oleuropein Prevents COVID-19?

A recent study done by world-renowned researchers like Debabrata Majumder, Mousumi Debnath, Kamal Nayan Sharma, and more has found that Mediterranean diets could be connected to a greater prevention for degenerative diseases.

This is partly due to this type of diet’s richness in high-phenolic olive oil, an ingredient that contains highly antioxidizing and anti-inflammatory compounds like oleanolic acid, oleuropein, and oleocanthal.

According to this study, various bioactive compounds like those mentioned above provide a cardioprotective measure, which studies in silico have linked to the phytochemicals that can be found in high phenolic olive oil.

Because of these bioactive compounds, and their effect on the human body, medicinal grade olive oil can be considered a tool that can help protect us against SARS CoV-2 thanks to the phytochemical composition of this type of oil.

phytochemicals blocking virus multiplication

While there have been countless studies done on the effects of polyphenols, oleanolic acid, and other bioactive compounds in olive oil, there is still incredible interest in how extra virgin olive oil can play a role in preventing and even treating COVID-19.

This study also states that the way that oleuropein and COVID-19 can be connected depends on how the olive oil is processed. If it can be processed in a way that maintains its polyphenolic constituents, it could provide a greater protection against things like non-communicable diseases and COVID-19.

In Summary

  • Bioactive compounds that are found in high phenolic olive oil play a role in COVID-19 prevention.
  • By maintaining polyphenolic constituents, olive oil can reduce the risk of non-communicable diseases as well as COVID-19.
  • Ongoing in silico studies are giving researchers and olive oil manufacturers greater insight into how extra virgin olive oil can be used as a natural dietary supplement that could protect our health and wellbeing against serious disease and illness.

How and Why do Olive Oil Compounds – Like Oleanolic Acid And/or Oleocanthal – Appear to Fight Coronavirus?

Part of the reason why ingredients found in high phenolic olive oils / HP EVOOs, like those available at HYPERELEON, appear to be so effective in treating disease, inflammation, and cell oxidization, is the fact that many of these ingredients are met exclusively in admirably high concentrations within olive oil's phenolic cluster.

This is already well-known for the pronounced effects on the human body.

olive oil polyphenols fight coronavirus

According to recent in silico, in vitro and computational studies being conducted all over the world, certain phenolic compounds can be considered anti-SARS-CoV-2 metabolites.

Some of these phenolic compounds include oleuropein, oleanolic acid, oleocanthal, hydroxy tyrosyl, verbascoside, and luteolin-7-glucoside. These phenolic compounds, in other words, can be used to increase the effectiveness of COVID-19 treatment, and the treatment of other serious cardiovascular, pulmonary, and metabolic diseases.

Olive leaf extract, which is rich in each of these phenolic compounds and more, has been hailed for its analgesic, immunomodulatory, and antipyretic properties. Because of its anti-inflammatory and anti-thrombotic activities, olive leaf extract is a great candidate for combatting respiratory illnesses like those associated with COVID-19.

A great example of this is presented by a study done at the Fayoum University Hospital in Egypt. In this placebo-controlled clinical trial, patients were randomly assigned to taking olive leaf capsules that each contained 50% oleuropein for 10 days.

This group was complemented by a control group that took placebos. Some of the outcomes that were expected and measured were symptom alleviation, improvement of CBC, CRP, ESR and AST analyses, and a 30-day mortality in a specific population.

What this study showed, in simpler terms, is olive leaf extract’s ability to reduce and minimize the effects of SARS-CoV-2 and the mortality rate of patients over the age of 65.

This is in line with results of a medical study that considered the effects of a Mediterranean diet on those suffering from COVID-19.

This study found that a diet rich in fruits, vegetables, and specifically high phenolic olive oil, was effective in reducing the time spent in hospital or on ventilators in patients over the age of 60. To measure the effects and long-term complications of COVID-19 on these various patients, further studies are being conducted.

In Summary

  • Extra virgin olive oil is rich in phenolic compounds like oleuropein, oleanolic acid, oleocanthal, hydroxy tyrosyl, verbascoside, and luteolin-7-glucoside.
  • The phenolic compounds are being studied to determine their effect on other serious cardiovascular, pulmonary, and metabolic diseases, including COVID-19.

Why is High-Phenolic Olive Oil the Best Source of Natural Polyphenols?

We touched on EVOO’s unsaturated nature earlier, but to go into a little more detail, EVOO – especially in its most phenolic-packed form – contains monounsaturated fatty acids.

Accompanied by certain other polyphenols like oleuropein and Hydroxytyrosol, these have shown anti-inflammatory and antioxidative properties in studies, which could also present significant antibacterial and antiviral action in patients suffering from COVID-19.

Did you know that, in the EU, high-polyphenol olive oil is entitled to bear the Health Claim that the polyphenols found within the oil contribute to the protection of blood lipids from oxidative stress?

It’s a bold claim, but that’s the power of high-phenolic EVOO – which is bursting with more than 30 different kinds of phenolic compounds.

We mentioned oleuropein and Hydroxytyrosol, but these are just two of dozens more, all of which may strengthen the immune system to act favorably should you ever contract COVID-19.

It’s important to note that high-phenolic olive oil also contributes to heart health – while reducing blood pressure, lowering cholesterol, and stabilizing blood sugar. This is crucial seeing as many patients who have suffered from severe COVID-19 infections had high cardiovascular risk factors like diabetes, obesity, and hypertension.

Olive oil – especially its high-phenolic EVOO kind – works hard to protect consumers against these very illnesses by protecting your heart and overall cardiovascular health.

In turn you’ll have a natural defense against COVID-19 among other viruses, seeing as ongoing evidence supports the idea that COVID-19 symptoms can be worse in people with compromised heart health.

Integrating high-phenolic EVOO into your diet is a smart way to strengthen your immune system while boosting your heart health and, in turn, skyrocketing your chance at beating the coronavirus should you end up contracting it.

In Summary

  • High-phenolic olive oil contributes to the protection of blood lipids from oxidative stress.
  • EVOO has 30+ different phenolic compounds.
  • High-polyphenol olive oil may strengthen your immune system.
  • High-phenolic EVOO delivers scientifically highlighted antibacterial action.

What is the Highest Quality EVOO on the Market?

highest quality olive oil

When choosing the best olive oil to add to your diet in an effort to reduce the potential adverse effects of COVID-19, there are four key phrases one must look out for: Cold-pressed, unfiltered, chemical-free, and not subjected to heat.

The process of cold-pressing is a traditional one that was originally used thousands of years ago before the emergence of heat-processing technology.

Historically, granite stones and hydraulic mat presses were used to cold-extract oil from olives in an effort to retain their antioxidants and pure, natural ingredients.

While we’ve certainly come a long way since using rocks to get this priceless oil out of olives, we’ve found a way to combine history’s lessons with newfound methods to preserve the integrity of EVOO.

The highest quality EVOOs on the market are bursting with natural, intrinsic polyphenols that are preserved through a cold-pressing procedure that eliminates the need for damaging heat processing.

Heat processing can render these powerful polyphenols useless, meaning you won’t be able to leverage any of their innate benefits to your wellbeing.

Seeing as the compounds found in EVOO are highly bioavailable, this means that they can easily enter the body’s circulation and deliver an active effect.

When you consume high-phenolic olive oil, you are consuming compounds with potent antibacterial properties that have been shown to defend the immune system against pathogens. Early in vitro studies highlight this.

In one particular 5-minute room temperature test, both tyrosyl and Hydroxytyrosol found in EVOO were shown to decrease Listeria monocytopenia activity. This bacterium is contracted from food that’s been contaminated.

In Summary

  • Always search for EVOO that is organic, cold-pressed, unfiltered, unheated, and chemical-free.
  • The best olive oils have priceless phenolic content.
  • Cold-pressing of olives preserves EVOO’s antioxidants among other natural ingredients.
  • Cold-pressing is the only way to enjoy the benefits of EVOO’s priceless polyphenols.

What is Medicinal Grade Olive Oil?

There is so much more to olive oil than what you see on your local store’s shelves.

Olive oils are assigned varying grades depending on their standards, and there are striking differences between most regular store-bought olive oils and their medicinal-grade counterpart – the latter of which is made mechanically without relying on excessive heat, chemicals, or filtering.

Look for Organic, Early Harvested, Cold-pressed, High-Phenolic, Unfiltered, Extra Virgin and Top Quality EVOO, as the distinct typical characteristics.

Extra virgin medicinal-grade olive oil is hailed in countless research studies for its richness in healthy monounsaturated fats, high numbers of antioxidants, anti-inflammatory properties, heart protection, and even stroke prevention.

In Summary

  • Olive oils are assigned different grades depending on variety, cultivation and extracting methods, phenolic content, quality, and efficacy.
  • Medicinal-Grade EVOO features monounsaturated fats, high phenolic content, and high antioxidant levels and organic, Early Harvested, Cold-pressed, High-Phenolic, Unfiltered, Extra Virgin and Top Quality are the distinct minimum characteristics that you should search for.
  • Medicinal-grade olive oil, provides protection against heart disease and even strokes.
