by | May 31, 2024 | Blog, Health & Wellness

What is Quercetin?

Quercetin is a powerful plant pigment found in many of the foods we eat. This natural compound belongs to a group of substances known as flavonoids, which are celebrated for their health benefits. You’ll find quercetin in a variety of colorful fruits, vegetables, and grains, where it contributes to their vibrant hues and offers numerous health advantages.

It has a yellow color and is not easily soluble in hot water, though it dissolves quite well in alcohol and lipids, and remains insoluble in cold water. It is considered one of the most commonly used bioflavonoids for treating metabolic and inflammatory disorders.

Quercetin is one of the most abundant dietary flavonoids, present in a wide variety of foods. You can find it in 

  • fruits (particularly citrus fruits)
  • green leafy vegetables
  • seeds
  • buckwheat
  • nuts 
  • flowers 
  • barks
  • broccoli
  • olive oil
  • apples
  • onions
  • green tea
  • red grapes
  • red wine
  • dark cherries, and berries like blueberries and cranberries

The highest concentrations of flavonols are found in vegetables such as onions and broccoli, fruits like apples, cherries, and berries, as well as in beverages such as tea and red wine.

Benefits

Antioxidant Properties

It stands out as a potent antioxidant. It works to combat free radicals in the body, which are unstable molecules that can damage cells and lead to chronic illnesses such as heart disease, cancer, and neurodegenerative disorders. Vitamin A, Vitamin C, and Vitamin E are dietary antioxidants, commonly present in vegetables and fruits which help to inhibit the free radicals. By incorporating quercetin-rich foods into your diet, you help safeguard your cells from this oxidative damage.

Reduces Inflammation

Inflammation is a natural response to injury or infection, but chronic inflammation can lead to various health problems. Quercetin has anti-inflammatory properties that can help reduce the production of inflammatory substances in the body. This makes it beneficial for conditions like arthritis, asthma, and other inflammatory diseases.

Heart Health Booster

Research suggests that it can support cardiovascular health. It helps lower blood pressure, reduces “bad” LDL cholesterol levels, and improves the function of blood vessels. These benefits contribute to a lower risk of heart disease and better overall heart health.

It has a special ability to stop fat from building up in new fat cells and can also cause existing fat cells to self-destruct. Additionally, it prevents the body from absorbing glucose from the blood, stops new fat cells from forming, and helps break it down.

Reduce the Risk of Neurodegenerative Disorders

Along with vitamin C, it helps protect human cells and skin structures from damage and prevents harm to brain cells. It shields brain cells from oxidative stress, which can lead to Alzheimer’s and other brain disorders. Flavonoids, like quercetin, protect brain cells from damage caused by toxins, reduce brain inflammation, and improve memory and learning. They also help prevent serious brain diseases and strokes that often affect older people. Eating foods rich in flavonoids or taking supplements can improve brain function and protect brain cells by helping them work better or grow new cells.

May have anti-cancer effects

Research has shown that diets rich in vegetables and fruits can help protect against cancer. Quercetin, found in these foods, may also have properties that fight cancer. It can slow down the growth of cancer cells, block substances that help tumors grow, and act as an antioxidant.

Natural Allergy Relief

For those who suffer from seasonal allergies, quercetin might offer some relief. It acts as a natural antihistamine by stabilizing mast cells and preventing the release of histamines, which cause allergic reactions like sneezing, itching, and congestion.

It helps fight allergies by stopping mast cells from releasing histamine and other allergy-causing substances, acting like a natural antihistamine. This ability has big implications for treating and preventing conditions like asthma and bronchitis. Mast cells, which are like gateways for the immune system, can be affected by emotional stress and the environment.

Anti-bacterial and anti-viral Effect

It has been found to have antibacterial properties that can fight off many types of bacteria, especially those that affect the stomach, lungs, urinary tract, and skin. Its ability to fight infections and stop bacteria from multiplying might also help fight viruses. Some viruses, like adenovirus, herpes simplex virus, Japanese encephalitis virus, and respiratory syncytial virus, seem to be particularly sensitive to flavonoids like quercetin.

Considering Quercetin Supplements

If you find it challenging to get enough quercetin from food alone, supplements are an option. They come in various forms, such as capsules, tablets, and powders, and are often paired with vitamin C or bromelain to enhance absorption. However, it’s important to consult with a healthcare professional before starting any new supplement, especially if you have existing health conditions or are on medication.

Quercetin is a versatile and powerful flavonoid that offers numerous health benefits. From its antioxidant and anti-inflammatory effects to its ability to support heart health and boost the immune system, quercetin is a valuable addition to any diet. Whether you choose to consume it through natural food sources or supplements, embracing the power of quercetin can lead to a healthier, more vibrant life.
