Quercetin is a type of plant compound called a flavonoid (a fancy name for a plant pigment) that contributes to the natural, vibrant colors of fruits and vegetables like apples, onions, berries, and tea. Flavonoids function as antioxidants, seeking out damaging free radicals and neutralizing them.* Free radicals are caused by the daily oxidative stress placed on our bodies, and they are linked to cellular damage, accelerated aging, and chronic health conditions.Â
Thorne’s Quercetin Phytosome offers the antioxidant benefits of a flavonoid, as well as its immune-supporting properties and the ability to support a healthy inflammatory response, which provides a range of health-promoting benefits.*Â
As a natural compound, quercetin is typically characterized by poor absorption into the bloodstream, which is why the quercetin used in Thorne products is provided as a quercetin phytosome. A quercetin phytosome complex enhances the benefits of quercetin by utilizing phytosome technology to optimize the nutrient’s bioavailability. Thorne’s Quercetin Phytosome is up to 20 times more bioavailable than quercetin extract alone, for maximum benefit from a smaller amount.*

Unique Benefits for Healthy Aging
Cutting-edge research is placing quercetin in the spotlight for healthy aging because of new research that shows quercetin helps reduce cellular senescence.* Senescent cells are malfunctioning cells that have stopped dividing but do not die and remain in the body. Environmental factors, along with regular aging, causes a buildup of senescent cells, which can be associated with biological aging and age-related disorders.

This pharmacy is a step above the average pharmacy. The staff are professional, caring and take pride in their work. CVS told my nurse they didn't have time to fill my prescription and to go elsewhere because they were busy. The nurse called Stark Pharmacy. They knew the prescription was for severe pain and had my prescription filled in 20 minutes so I could have it before they closed for the night. That is customer service at its finest!!Elizabeth B.
Karen (Pharmacist) and all supporting staff have been stellar. I've been going there for bioidentical HRT for 14 years now and have never been disappointed.Karen H.
I am new to Stark Pharmacy, but my experience has been so personable and educational, I had to leave a review. I recently spoke with John Schafer about my new treatment plan which includes compounded medications. He was clear, patient & personable. He anticipated questions & concerns I hadn't yet thought of myself. In today's environment of "hurry up, take a number, wait & NEXT", it was a comforting & encouraging difference to not feel rushed. All my questions were answered with sincerity & clarity. I didn't feel silly or like an inconvenience.Tracy C.
The pharmacists were able to make the medications I needed that weren't available in a safe commercial form. One is a life-saving medication for me.BJ Doebele
