Quercetin: Sources, Uses, Benefits, and more

Taking care of our health from the inside out is now more important than ever! 
We have spent some time putting together our favorite natural health boosters. In this blog post we take a look into the benefits of Quercetin. Providing so many health benefits, it’s definitely high on our list.  Check out this helpful blog to learn if quercetin is right for you.

What is Quercetin?

Quercetin is a powerful antioxidant, antihistamine and anti-inflammatory, and is the most prominent of over 5,000 flavonoid compounds found in food. Flavonoids are what gives flowers and fruits their beautiful, vibrant colours and have been linked to several health benefits, including reduced risk of heart disease, cancer, and degenerative brain disorders. 

Sources of Quercetin:

Quercetin is found in many plants (especially in the peel or outer layer) and foods such as:

  • yellow and green peppers
  • onions and shallots
  • red wine
  • cooked asparagus
  • cherries
  • tomatoes
  • red apples
  • red grapes
  • broccoli
  • kale
  • red leaf lettuce
  • berries 
  • green tea 
  • capers

Also found in: Ginkgo biloba, St. John's wort, American elder, and Buckwheat tea and is also available in supplement form. 
Traditional and organic growing methods can greatly increase the amount of quercetin contained in foods, (Organic tomatoes can have up to 79% more quercetin) compared to commercially grown foods. 

Coffee has been linked to a lower risk of Alzheimer’s disease. Research shows that quercetin is the key ingredient in coffee that can help protect against this illness. 

Why take Quercetin?

As always with any supplement, it's important to ask your doctor if it's right for you.  Here are some benefits of quercetin:

Anti-inflammatory properties:

Quercetin has antioxidant and anti-inflammatory effects which may help reduce inflammation, kill cancer cells, control blood sugar, and help prevent heart disease.
While a little inflammation is necessary to help your body heal and fight infections, persistent inflammation is linked to health problems, including certain cancers, as well as heart and kidney diseases. Quercetin has been shown to ease painful rheumatoid arthritis symptoms. 

Eases respiratory virus symptoms:

Taking quercetin has been shown to reduce the damaging effects of free radical damage during an influenza virus infection and helps to reduce symptoms of upper respiratory infections. Exciting research is currently being conducted on quercetin’s ability to block the entry of certain viruses, (such as coronavirus) by stopping the viruses from binding to the receptors in cells and prevent it from multiplying inside the body. More about this exciting research below!


Allergy and Asthma Control:

Quercetin is also used as a preventative treatment for allergies and asthma because of its antihistamine properties. When taken before exposure to allergens, it is shown to keep symptoms at bay. Great news with allergy season upon us!

Blood Vessel Health:

Quercetin protects the cells and blood vessels from the damaging effects of free radicals and improves blood vessel strength. 
Quercetin may also help to reduce blood pressure levels by having a relaxing effect on blood vessels, decreasing the risk of heart disease. 

Brain health:

Quercetin inhibits the activity of enzymes that can break down neurotransmitters. This may lead to elevated levels of norepinephrine, which stimulates brain activity and boosts cell function to keep your brain and body healthy.  

Diabetes Management:

Quercetin blocks the enzyme that leads to accumulation of sorbitol, which has been linked to nerve, eye, and kidney damage in diabetics. It may also aid in blood sugar control and reduce fasting blood sugar levels. Protecting against complications of diabetes. 

Exciting Canadian Research:

There have been many studies conducted on quercetin as a treatment for viral infections. Dating back 15 years to the SARS outbreak, Canadian researcher Michel Chrétien and his team began testing his theory that quercetin was an antiviral drug that could fight a range of viruses. 

They also continued their study when an Ebola outbreak struck West Africa in 2014. When the COVID-19 health crisis broke out in Wuhan, China, in recent months, Chrétien and his team began the process of exploring the idea that quercetin may work on COVID-19 symptoms. Clinical trials are now underway in China. 

Another easy (and delicious!) way to strengthen your virus fighting immunity and boost your daily nutrition:
