Science Popularization - Natural Flavonoid Quercetin

 Quercetin is a natural flavonoid compound derived from fruits, vegetables and traditional Chinese medicinal materials. Its benefits to the human body are as follows:

1.Quercetin has a powerful antioxidant function. It can eliminate free radicals in the body and reduce the damage of oxidative stress to cells. Scientific research indicates that quercetin can inhibit the production of harmful free radicals such as superoxide anions and hydroxyl radicals, which helps delay cellular aging and reduce the risk of chronic diseases caused by oxidative damage. ​

2.In terms of cardiovascular health, quercetin can lower the levels of cholesterol and triglycerides in the blood, inhibit platelet aggregation, and thereby reduce the occurrence of atherosclerosis. In addition, quercetin also has a positive effect on the respiratory system. It can relax the smooth muscle of the bronchi.

3. It can also enhance immunity, activate the activity of immune cells, and help the human body resist the invasion of viruses and bacteria. ​

The suitable population for quercetin is relatively wide.

Firstly, due to the decline in physical functions, middle-aged and elderly people are more vulnerable to oxidative stress and chronic diseases. The powerful antioxidant and anti-inflammatory properties of quercetin help them maintain good health.

Secondly, people who are constantly exposed to high-pressure working environments and have irregular lifestyles are prone to problems such as weakened immunity and physical fatigue. Quercetin can help them enhance their immunity and relieve fatigue.

Furthermore, for patients with chronic inflammatory diseases such as arthritis and rhinitis, taking quercetin under the guidance of a doctor can help alleviate symptoms. In addition, paying attention to lung health, especially for long-term smokers or those living in polluted environments, the protective effect of quercetin on the respiratory tract can add an extra layer of protection to their lung health. ​

However, there are also many precautions when using quercetin. Due to the low bioavailability of quercetin, the absorption effect is limited when directly consuming foods rich in quercetin (such as Onions, apples, green tea, etc.). If choosing quercetin supplements, attention should be paid to the product quality and dosage. Excessive intake of quercetin may cause gastrointestinal discomfort, such as nausea, vomiting, diarrhea and other symptoms. Therefore, it is essential to follow the product instructions or medical advice and not to take it in excess at will. At the same time, quercetin may interact with certain medications. People who are taking antihypertensive drugs, hypoglycemic drugs, anticoagulants, etc. should consult a doctor before supplementing quercetin to avoid affecting the efficacy of the drugs or causing adverse reactions. In addition, pregnant women, lactating women and children are not recommended to take quercetin on their own as relevant safety studies are not yet sufficient. ​

With the continuous in-depth research on quercetin, this natural flavonoid compound is providing new options for public health management with its rich health benefits. However, during the application process, consumers need to scientifically understand its function and use it reasonably in order to better exert the health value of quercetin.
