Data suggests that quercetin sales in the U.S. skyrocketed by 229% between 2020 and 2022. It has become one of the staple ingredients in the U.S. lung supplement market. Today, join Nutri Avenue to find out about Quercetin for lung health. What’s so great about it?
What Is Quercetin?
Quercetin is derived from the Latin word “Quercetum”. It means oak forest and belongs to a subclass of flavonoids. It is a natural ingredient found in a wide range of plants. The bulk quercetin powder offered by Nutri Avenue is extracted from Sophora Japonica. It is the unflowering bud of the Sophora Japonica tree. It has a high content of Quercetin within it. Hence, it can also be referred to as acacia flower extract.
The bioavailability of Quercetin in everyday foods is relatively low. One study found that the bioavailability of Quercetin from apples was 17%. The bioavailability of Quercetin from onions was 34%.
Therefore, if Quercetin is utilized for disease prevention purposes, the dosage that needs to be consumed will be very high. It cannot be achieved by daily diet alone. It is when the need for quercetin supplements arises.
Quercetin For Lung: Is There Any Evidence?
In ancient times, the use of Quercetin was documented to treat respiratory disorders. For example, in the Shennong Ben Cao Jing (Classic of the Materia Medica of the Divine Husbandman), it is written that Quercetin can clear heat and remove toxins, moisturize the lungs, and relieve coughs.
Modern medical research has also found that Quercetin has a positive impact on protecting the lungs in a variety of ways, such as relieving lung inflammation.
From the Hungarian-American biology professor Albert Zheji in the laboratory mice experiments, research has found that the injection of Quercetin can promote lung waste metabolism. At the same time, it has the effect of repairing inflammatory damage in the lungs.
A clinical trial conducted on patients with chronic obstructive pulmonary disease (COPD) showed that Quercetin improved lung function and reduced inflammation. [1]
A clinical trial conducted on patients with asthma showed that Quercetin improved lung function and reduced inflammation. [2]
A randomized, double-blind, placebo-controlled clinical trial was conducted at the University of Michigan Lung Disease Institute. Patients with chronic lung obstruction who had a smoking history of ten years or more were divided into a placebo group, a 500 mg quercetin group, a 1000 mg quercetin group, and a 2000 mg quercetin group. The four groups underwent a 6-month observation experiment. The results of the study showed no serious adverse events or major adverse changes in lung function in any of the groups. Quercetin was effective in reducing disease severity in patients with COPD. It is also recommended that patients with chronic pulmonary obstruction use quercetin supplements as a first step in their therapeutic agent.
In vitro experiments have also explored the effects of Quercetin on the proliferation and apoptosis of lung cancer cells. The results showed that Quercetin inhibited the growth and promoted the apoptosis of lung cancer cells. [3]
In addition, several studies have suggested that Quercetin may play a role in managing metabolic disorders through several different mechanisms, such as antioxidant activity, reduction of insulin resistance, elevation of insulin levels, and blocking calcium channels. It lowers blood pressure and regulates hyperlipidemia and hyperglycemia.
Formulation: Quercetin For Lung With Vitamin C, etc.
Quercetin is often used in conjunction with other ingredients to enhance lung protection. For example,
Together, Quercetin with Vitamin C and other nutrients can enhance immunity and improve body resistance.
Quercetin with Ganoderma lucidum extract can achieve lung purification and asthma relief and deeply nourish the lungs.
A new study suggests that the mineral zinc may have a potential benefit in reversing lung damage and improving survival rates in patients with idiopathic pulmonary fibrosis. Therefore, Quercetin with zinc is also a noteworthy formula.
On top of that, like magnesium, omega-3 fatty acids, and vitamins D, A, and E, these supplement ingredients have been shown to improve or protect lung health.
Conclusion
This article focuses on the significant role of Quercetin for lung health in this field. In fact, Quercetin has been shown to be beneficial in assisting with COVID treatment, enhancing aerobic performance, weight loss, blood sugar control, and slowing neurodegenerative diseases.
The natural quercetin powder extracted from Sophora Japonica offered by Nutri Avenue will further contribute to the growth of the global lung supplements market, including North America, South America, Mexico, Poland, Hungary, France, the U.K., and others.
