Quercetin is naturally abundant in plant foods and as a result is highly bioavailable. Quercetin Lowers Cholesterol, Fights Atherosclerosis 6-12 Laboratory models of aging, ranging from simple yeasts and primitive worms to cultured human cells, demonstrate that quercetin alone produces up to a 60% increase in life span! 6,8-12 In addition, quercetin has been found to be cancer chemopreventive as well as reduce allergic reactions, boost immunity, and protect the cardiovascular system.ĭue to its synergies with resveratrol, health-conscious people often obtain some quercetin in science-based resveratrol formulas they already use. 6 Several recent studies show that organisms exposed to high levels of quercetin live longer, healthier lives. Quercetin is attracting intense scientific interest for its unique anti-aging and immune-boosting activities. One flavonoid in particular, quercetin, is found in a broad range of foods, from grape skins and red onions to green tea and tomatoes. Yet when we consume plants as food and beverages, the protective benefits of these same flavonoids are readily transferred to our bodies! 5 1-4 For humans, these same conditions can be lethal. One reason that plants hold so much potential for human health is that they are able to withstand a variety of destructive forces such as environmental radiation, oxidative damage, and chemical toxins due to their unique ability to manufacture complex molecules called flavonoids. 1-6.Many of our most powerful medicines, including those for diabetes, chemotherapy, and cardiovascular health, are derived from plant extracts.
