What is quercetin and how does it help with allergies?

Have you ever heard of quercetin? This natural compound is becoming increasingly popular for its potential benefits in alleviating allergy symptoms. 

A total of 8% to 10% of the world’s population suffers from one or more allergic diseases.

In addition to significantly affecting the quality of life of patients and their families, allergies increase healthcare costs and reduce the economic strength of a country.

What exactly is quercetin?

Quercetin is a bioflavonoid, an antioxidant found in various fruits, vegetables, tea leaves, red onions, and apple peel. Its strong anti-inflammatory properties make it attractive in combating allergy symptoms. Numerous studies show that this natural ingredient helps reduce inflammation and stabilize mast cells, which can relieve itching, sneezing, and runny nose.

In a normal and proper human diet, the content of quercetin typically ranges from 15 to 500 mg per day, which has extremely good preventive significance for human health, and there are no limitations when consumed through food.

What are the health benefits of quercetin?

Research has shown that it has anti-inflammatory, anti-allergic, anti-rheumatic, antiviral, and anti-carcinogenic effects, and its positive effects on the development of diabetes and its consequences, as well as on numerous enzyme functions in the body, are also known.

Allergies, asthma, hay fever

Quercetin prevents the release of histamine in the body, which causes allergy symptoms such as sneezing, itching, and runny nose. This leads to a better quality of life for people suffering from allergies, allergic rhinitis, and hay fever, including better sleep.

In the lungs, it reduces the synthesis of the enzyme α5-lipoxygenase, which positively affects asthma symptoms.

Anti-inflammatory effects of quercetin

Study data indicate that quercetin supplements can improve athlete performance and have the ability to increase cellular energy and physical endurance by up to 13.2%.
A study conducted on triathletes showed benefits in terms of endurance, performance, recovery time, and oxidative stress.

Interstitial cystitis (IC, non-infectious inflammation of the bladder)

There are suggestions that people with IC could benefit from taking higher doses of flavonoids like quercetin,especially if they have a history of elevated IgE antibodies. Some people have found that taking quercetin supplements reduced IC symptoms.

Cancers

Scientists believe that quercetin and other bioflavonoids from fruits and vegetables are important in preventing cancer development. People who eat more fruits and vegetables are less likely to develop certain types of cancer.

Dosage and notes

It is recommended to take quercetin supplements along with vitamin C and bromelain, with which it has a synergistic effect.

Take occasional breaks in the use of quercetin supplements.

Quercetin is a safe dietary supplement if used in recommended doses (doses higher than 1g/day can impair kidney function!).
