Product Information


Quercetin 500 provides the unique benefits of one of nature’s most powerful protective molecules. Like so many of nature’s most beneficial plant-based compounds, quercetin is a polyphenol and flavonoid. In fact, flavonoid polyphenols are the beneficial compounds that make many healthy foods so healthy, such as green tea, red wine and chocolate. Quercetin is uniquely abundant in capers, red onions and cilantro, but also rich in many other healthy foods. Quercetin has long been the subject of extensive research validating its protective benefits to diverse systems in the body. Quercetin is well known for its benefits promoting healthy circulation and supporting the structure of our blood vessels, veins and capillaries. More recently, quercetin has been recognized for its supportive benefits to the cardiopulmonary system, including the fragile tissues of both the heart and lungs. Quercetin has also been shown to support immune system function, as well as the normally problematic aging prostate gland. Quercetin’s impressive body of research has made it a popular ingredient in nutritional supplements; however, its benefits are limited due to its extremely poor absorption. We overcome these absorptive challenges by complexing quercetin with phosphatidyl choline (PC), which is the predominant phospholipid found in the brain and liver. This unique phospholipid complex protects quercetin from digestive damage while also dramatically increasing its absorption. This natural combination of quercetin with PC ensures you receive all the remarkable benefits of this extraordinary natural molecule.

Helps with blood circulation, especially my feet! I take 2 of these per day and have found it works good with Andrew's Vien and Circulation support for healthy feet and legs. Plus taking Andrew's supplements gives my Doctor unbelievable smiles when EVERYTHING in my blood work comes out perfect at over age 62! Worth every penny.

Life-saving!!! While I realize Andrew cannot claim any medical benefits, I'll share my fantastic experience with Quercetin. Three years ago I was diagnosed with a thoracic aortic aneurysm, which measured 4.2 cm. After taking Andrew's Quercetin for one year, my latest CT scan indicated the aneurysm shrank to 3.8 cm and according to my cardiologist, is no longer classified as an aneurysm. I followed the science and it led me to this life-saving product. THANK YOU, ANDREW for sharing your knowledge and providing us the access to obtain such wonderful, quality vitamins and supplements. I've been a customer for 10+ years and will continue to purchase your products as long as you keep making them!!!

Best Quercetin Product I've Taken I have taken other quercetin products for prostate benefits. This is the only product I've taken that that has had a positive impact on my symptoms. Thank you for offering a quality product that has no negative side effects.
