Quercetin Logo.png

Quercetin is a flavonoid that is found in citrus fruits and other sweet edibles. Quercetin is one of nature’s most potent antioxidants and may be associated with lowering the risk of heart disease and degenerative diseases. It also plays an essential part in fighting free radical damage which causes aging and inflammation.

Research shows that food containing natural quercetin is associated with less inflammatory health problems, including lowering the risk of heart disease and degenerative disease. It acts as a significant bioflavonoid in our diets which helps slow the aging process. This is because it lessens the effects of oxidative stress on the body.

Oxidative stress takes place in all of us but is increased by things like a poor diet, high levels of stress, lack of sleep, and exposure to chemical toxins. Quercetin also plays a role in regulating the immune system’s response to outside stressors through cell signaling pathways called kinases and phosphatases, two types of enzyme and membrane proteins needed for proper cellular function.
