What is Quercetin?

Need some relief from allergies? It’s Quercetin to the rescue! If your diet is filled with fruits and vegetables, you are getting an abundance of Quercetin. Yes, it’s a strange sounding word (it’s pronounced kwur-si-tin), but it’s a wonderful, naturally occurring compound that provides many health benefits in addition to allergy relief, such as heart health, stronger immune system, pain relief, and even younger-looking skin.

In this blog article discussing Quercetin, LifeSeasons’ featured weekly ingredient, you’ll learn what Quercetin is, how this ingredient supports respiratory health, and lastly, you’ll learn about the benefits and uses of this compound.

Quercetin, What is it?

Quercetin is one of the best-known flavonoids (a diverse group of plant chemicals) and is found in many fruits, vegetables, leaves, and grains.1 Because it’s considered a plant pigment, Quercetin is prominently found in colored fruits and vegetables, especially those in red and orange pigmentation.2 The strong antioxidant and anti-inflammatory effects of Quercetin play a noticeable role in our health.

As an antioxidant, Quercetin helps stop cells from being damaged by free radicals (waste produced by cells), thus protecting the immune system; as an anti-inflammatory, Quercetin inhibits certain chemical pathways from generating uncomfortable or painful inflammation.2

In your diet, Quercetin is most significantly found in onions, apples, citrus, kale, blueberries, and sweet potatoes, plus it can be found in green tea and red wine.2,3

9 Quercetin Benefits & Uses: Health Conditions Helped By Quercetin

With Quercetin being a powerful flavonoid, there is a wide range of health benefits, including its ability to reduce inflammation, eliminate pain, protect against cardiovascular diseases, act as an anti-cancer, boost the immune system, reduce histamines, and decrease irritation of the skin.

Quercetin Benefits and Uses

Let’s take a closer look at the amazing benefits that can be ours, all thanks to Quercetin.

  1. Anti-Inflammatory – Inflammation is something that everyone experiences, and it happens when the body attempts to protect itself from harmful stimuli. However, chronic inflammation can lead to different conditions, which can include cancers, heart disease, and rheumatoid arthritis.4 Though further research is currently being done, Quercetin is thought to lower inflammation and inflammatory diseases like IBS because of its antioxidant properties.5 
  2. Pain Fighter – Because of the anti-inflammatory effects of Quercetin, painful conditions can be minimized. Autoimmune conditions, such as arthritis, and painful infections, such as prostate and respiratory infections, can benefit from Quercetin.5 
  3. Natural Antihistamine – Histamines are chemicals in your body that your immune system makes, and they help your body to get rid of an allergen. In order to get rid of the allergen, the histamines cause you to sneeze or cough, have watery eyes or a runny nose, and feel itchy because it wants those allergens out of your body. The abnormal release of histamines can negatively impact your respiratory system leading to multiple health complications, such as redness, irritation, and swelling.8 Being loaded with antihistamines, Quercetin can help with these respiratory problems. It influences intracellular enzymes and reduces excessive histamine excretion.3 
  4. Helps Asthma - Quercetin functions as a bronchodilator (a drug that opens the airways of the lungs) and reduces the amount of inflammatory or allergic reaction chemicals in the body.Therefore, Quercetin can reduce the severity of asthma attacks that react to those chemicals, and also reduce various forms of congestion that are unrelated to asthma.2,3 
  5. Cardiovascular Health - Studies have shown that the consumption of flavonoids, specifically Quercetin, promotes overall cardiovascular health.3 First, it encourages blood flow. Secondly, researchers have observed that Quercetin’s antioxidant action protects against LDL cholesterol (the “bad” cholesterol) oxidation, and this may be beneficial because oxidation causes LDL cholesterol to stick to artery walls.3 Too much LDL cholesterol could cause atherosclerosis, heart attacks, and strokes.
  6. Balanced Blood Pressure – Along with supporting cardiovascular health, Quercetin naturally promotes balanced blood pressure. A randomized, double-blind placebo-controlled crossover study evaluated the effect of Quercetin supplementation and reported that the participants experienced a stabilization in systolic, diastolic and average arterial pressure.3 
  7. Anti-Cancer - Quercetin, like other flavonoids, seek out free radicals in the body and neutralize them before they can damage the bodily systems, and therefore, it becomes a potential in being an anti-cancer agent.6 Quercetin has been connected to a reduction in pancreatic, prostate, colorectal, and skin cancers, and although studies are ongoing, signs are pointing toward Quercetin being an important natural cancer-fighter.2,5 
  8. Protects Against Stress - When your body is stressed, it produces cortisol. Cortisol is a hormone that produces that “fight or flight” response. Although this is normal, when your stress levels are high and ongoing, cortisol can damage muscle tissue, leading to protein breakdown in the body. Quercetin can fight these effects during times of extended stress as it suppresses the enzyme necessary for cortisol release.7 
  9. Promotes Healthy Skin - According to dietitians, eating a Quercetin filled diet (lots of colorful veggies and fruits) can contribute to youthful looking skin.8 It nourishes your skin naturally and enhances your complexion as well. Being an antioxidant, Quercetin has an ability to fight factors that promote early aging.8

Quercetin Side Effects & Awareness Tips

Research agrees that Quercetin doesn’t have any inherent dangers; after all, it’s naturally found in foods-of-the-earth. According to WebMD, there aren’t specific reported side effects from consuming a diet filled with Quercetin foods or taking a supplement by mouth short-term.9 However, as with many things, if taken in high doses, there could be some risks, which include headaches, tingling of arms and legs, and in extreme cases, there could be kidney damage.9

If you’re pregnant or nursing, talk with your doctor first if you’re considering taking a Quercetin supplement.
