Quercetin: Cardiovascular Benefits and More

  This post may contain affiliate links

Have you ever visited a farmer’s market at the peak of growing season? Maybe you’ve admired the colorful arrangement of vegetables in your local market, where the vibrant hues of fruits and vegetables are not just a feast for the eyes but a treasure trove of health benefits. 

Among the apples and asparagus, one compound stands out for its remarkable heart-protective qualities – quercetin. This hidden gem, nestled within the fibers of common fruits and vegetables, is a powerful ally in the fight against cardiovascular diseases.

What is Quercetin?

Quercetin is a remarkable substance found in many plants that we often see in our daily diets. It belongs to a group of plant compounds known as flavonoids. These compounds are like nature’s protective agents, working to safeguard plants, and when we consume them, they offer similar protection.

The standout feature of quercetin is its antioxidant properties. Antioxidants are like bodyguards against tiny, harmful particles known as free radicals. Imagine these free radicals as little troublemakers that roam around in our bodies, causing damage to our cells. This damage can lead to a variety of health problems, especially those related to the heart and blood vessels, like cardiovascular disease.

Free radicals are a normal part of our body’s processes, but factors like pollution, smoking, and stress can increase their numbers dramatically. This is where quercetin steps in as a hero. It helps neutralize these free radicals, reducing their ability to cause harm. By doing so, quercetin acts as a valuable ally in maintaining our overall health, particularly in protecting our heart and preventing related diseases.

Heart Health Hero

Quercetin is making waves in the health world for its potential role in fighting atherosclerosis, a major cause of heart disease. Atherosclerosis slowly narrows and hardens the arteries, leading to heart attacks and strokes, two of the top health threats in the United States.

Research, including a notable study with rabbits on a high-cholesterol diet, has highlighted quercetin’s impressive effects. It not only mitigated the diet’s damaging impact on arteries but also helped reduce arterial plaque. This is significant since plaque buildup is a key factor in many heart-related emergencies.

What’s more, quercetin activates a process called reverse cholesterol transport. It’s like a cleanup operation where HDL cholesterol picks up excess cholesterol from arteries and ferries it to the liver for disposal.

Quercetin also supports the endothelial cells lining our blood vessels, crucial for regulating blood flow and pressure. It boosts the production of nitric oxide, which tells blood vessels to relax, enhancing blood circulation. This blend of benefits positions quercetin as a promising player in maintaining heart health and preventing serious cardiovascular events.

Other cardiovascular benefits of quercetin include: 

  • Wards off abnormal heart rhythms: Studies show that quercetin has the potential to keep arrhythmias such as AFib at bay. 
  • Prevents blood clots: Research indicates that quercetin may help to prevent blood clots and keep the blood flowing smoothly.
  • Lowers blood pressure: Evidence suggests that quercetin may help to lower blood pressure. A meta-analysis showed that 500 mg of quercetin daily reduced elevated blood pressure. 
  • Prevents Aneurysms: Animal studies show quercetin can reduce the incidence of abdominal aortic aneurysms, which can be fatal if they rupture. 

Nature’s Bounty: Dietary Sources

Obtaining nutrients directly from natural food sources is always the best approach, and quercetin is no different. Vegetables such as onions, capers, broccoli, kale, and dill are all high in quercetin. 

Fruits like dark berries and apples are also rich in quercetin. Green tea is also a good source of this nutrient. Including these foods in your diet offers quercetin and a spectrum of other nutrients essential for overall health.

Evidence-Based Supplements

Though natural sources are ideal, they may not always provide sufficient quercetin for therapeutic effects. This is where supplements step in. Natural Heart Doctor offers a handful of choices formulated to deliver optimal quercetin levels. They ensure a consistent intake, beneficial for those seeking targeted cardiovascular support.

  • OptiLipid, formulated by cardiologist Jack Wolfson, offers a natural alternative to statins for maintaining healthy cholesterol levels, effectively balancing LDL and HDL without the blood sugar issues linked to statin drugs.
  • Daily Defense combines quercetin with other antioxidants, aiding in daily protection against environmental and dietary stressors. 
  • Quercetin by Pure Encapsulations offers a pure, high-potency quercetin, ideal for those who require a focused approach to heart health. 

Next Steps 

Quercetin may not be a supplement you’ve heard a lot about, and that’s unfortunate, given its role in heart health. You can find it in many colorful foods or as a supplement, making it a key part of staying healthy and keeping your heart in good shape.

About Dr. Lauren Lattanza NMD, FACC

Dr. Lattanza Office Visit with Patient

As a Naturopathic Physician, I am trained to treat the whole person and get to the root cause of disease.

I went to Arizona State University where I graduated with a bachelor’s degree in psychology with a depth in physiology and minor in Spanish. After my undergraduate degree I was working on prerequisite classes towards medical school, which is when I came to learn that my values identified best with the principles of naturopathic medicine. I knew that I wanted to help patients identify the causes of disease and be able to offer treatments which would improve their health rather than simply treating symptoms.

I dedicated the next 4 years to the Southwest College of Naturopathic Medicine in Tempe, Arizona where I attained my Doctorate of Naturopathic Medicine. I served as Class President all 4 years, Board of Trustees – Student Trustee, spoke as the Club President for our branch of Toastmasters, and was voted by my peers and attending physicians to earn the Outstanding Leadership Award for the Class of 2020. Throughout medical school I took it upon myself to work alongside MDs, DOs, chiropractors, and functional medicine practitioners in addition to naturopathic physicians.

As a Spanish speaking student, I was able to volunteer with community clinics around Phoenix and provide free healthcare to low-income families. Due to this combined exposure, I came to find my passion in treating cardiometabolic and digestive disorders that are all too common, yet largely preventable. I took the opportunity to learn the broad spectrum of healthcare so I can ensure that I am able to provide my patients with the best options.
