Review I have significantly reduced my PSA readings using Quercetin Plus. My readings had been cosistently increasing each month until I started taking Quercetin PLus. My readings immediately stopped the increase and have come back down to a more acceptable level. I beleive Querctin Plus has been the factor in the good news for me. The use of Quercetin Plus was suggested by my Oncologist after trying some prescription medicine. Give it a try.
