What is Quercetin?
Quercetin is a flavonoid, a type of plant pigment found in many fruits, vegetables, and grains. Quercetin is one of the most abundant dietary flavonoids present in various foods, including fruits like citrus and apples, vegetables such as onions and broccoli, and beverages like tea and red wine. It is particularly abundant in foods like apples, onions, and berries.
Flavonoids such as quercetin are known for their potential antioxidant properties, which may help neutralise free radicals and reduce oxidative stress.
This reduction in oxidative stress could contribute to better overall health by potentially lowering the risk of chronic diseases and slowing the ageing process¹. approximately 45 years in 1900 to over 75 years today.
This significant improvement is a testament to advancements in healthcare, nutrition, and overall living conditions. Understanding the factors that contribute to longevity is crucial for developing effective strategies to promote healthy ageing and extend the human lifespan.
The potential antioxidant capability of quercetin may support cellular health, protecting against damage that can lead to a variety of health concerns. By incorporating more quercetin-rich foods into your diet or using supplements, you may bolster your body’s natural defences against environmental and internal stressors².
