Quercetin is a bioflavonoid common in the plant kingdom, especially high in onions, red wine, and green tea. It is one of the most biologically active flavonoids. Quercetin acts as a potent polyphenol antioxidant and immune system modulator.* Many of its immune support attributes are enhanced by its synergistic relationship with vitamin C. Quercetin is highly active in the skin and lining of the digestive tract.*
Quercetin has a stabilizing effect on the immune system, helping various types of immune cells maintain their composure under stress.* This helps provide tolerance for irritants such as pollen.* Quercetin is known to modulate the behavior of the gene signal NF-kappaB, the crucial signal determining how a cell naturally manages stress and inflammation.*
Quercetin interacts with bones at a fundamental level (NF-kappaB), favorably influencing the behavior of both osteoblasts (bone building cells) and osteoclasts.* Quercetin is one more natural compound that assists optimal bone health.*
Quercetin provides a variety of immune support features. It has a modulating effect on immune system signals, helping to calm down inappropriate excess. It helps to nourish mast cells so they are more stable and less likely to release histamine. As such, Quercetin is a popular support nutrient for mild reactions to seasonal pollens and other irritants. It is also known to enhance macrophage function, assisting lymphatic function. Quercetin, Immune Plus™, and Oregano Oil is our most popular combination for natural sinus support.*
