Quercetin: Your centuries old traditional medicine

Quercetin from the Japanese Pagoda Tree

Quercetin (Sophora japonica)

Our Quercetin is derived from the Japanese Pagoda Tree (Sophora japonica) which is a deciduous Tree growing to 20 m (65ft) by 20 m (65ft). Quercetin is a natural flavonoid and can also be found in small amounts in various fruits, vegetables, and grains. It has been used for centuries in traditional medicine to treat a variety of ailments. Recently, researchers have been studying the potential health benefits of quercetin, including its ability to support the immune system and its interaction with zinc.

Benefits of Quercetin:

  1. Anti-inflammatory properties: Quercetin has been shown to have potent anti-inflammatory properties, which can help to reduce inflammation throughout the body. This can be beneficial for individuals with chronic inflammatory conditions such as arthritis, as well as for athletes who experience inflammation as a result of intense training.
  2. Antioxidant activity: Quercetin is a powerful antioxidant that can help to protect the body against oxidative stress. This can help to reduce the risk of chronic diseases such as cancer, heart disease, and diabetes.
  3. Cardiovascular health: Quercetin has been shown to have a positive impact on cardiovascular health. It can help to reduce blood pressure, lower LDL cholesterol levels, and improve blood flow. These effects can help to reduce the risk of heart disease.
  4. Potential anticancer properties: Some studies have suggested that quercetin may have anticancer properties. It has been shown to induce apoptosis (cell death) in cancer cells and inhibit tumor growth in animal studies.
  5. Cognitive health: Quercetin has been shown to have positive effects on cognitive health. It can help to improve memory and reduce cognitive decline in animal studies, and some human studies have suggested that it may have potential as a treatment for Alzheimer’s disease.

Quercetin and Immunity:

Quercetin has been shown to have a positive impact on the immune system. It can help to stimulate the production of immune cells, including T-cells and natural killer cells. Additionally, quercetin can help to reduce inflammation, which can impair immune function.

Quercetin and Zinc:

Quercetin has been shown to enhance the absorption and effectiveness of zinc. Zinc is an essential mineral that plays a critical role in immune function, wound healing, and DNA synthesis. When taken together, quercetin and zinc can have a synergistic effect on immune function and overall health. This is the primary reason why ImmuneX365 contains Quercetin but as you can see, it has many other benefits as well.


Quercetin has potent antioxidant properties and plays an important role in helping your body combat free radical damage, which is linked to chronic diseases. Research has linked quercetin’s antioxidant properties to various potential health benefits, including reducing inflammation, lowering blood pressure, and combating allergies.

Quercetin is also available as a dietary supplement in powder and capsule form. People take this supplement for several reasons, including boosting immunity, fighting inflammation, aiding exercise performance, and maintaining general health. A review of 11 human studies found that taking quercetin may slightly improve exercise performance. Quercetin has also been shown to have anti-inflammatory effects that might help reduce swelling, control blood sugar, and help prevent heart disease. However, it is important to note that more research is needed to fully understand the potential health benefits of quercetin supplements.
