However, quercetin has low water solubility, oral bioavailability [21, 22], and additionally decreased human bronchial epithelial BEAS-2B cell viability in a dose- and time-dependent manner [23, 24]. Given this background, the aim of the study was to evaluate the potential effect of 3 months' supplementation with Quercetin Phytosome<sup>®</sup> Quercetin with Bromelain, 50 vegan capsules. Introduction. This article explores quercetin’s uses, benefits, side effects, and dosage. It has shown to have some activity in reducing symptoms for acute sinusitis2. COVID 2(8) (2022), 1139-1182 Zelenko protocol 1. Generic name: bioflavonoids Medically reviewed by Drugs. As shown in Table 2, There was no significant difference in considered parameters between the two groups at baseline. For more difficult cases, added: ivermectin, Anti-coagulants, steroids: budesonide, prednisone, home oxygen. Temp started to rise to 99. in hospitalized COVID-19 patients associated with pneumonia, intravenous administration of quercetin/polyvinylpyrrolidone, followed by Keywords: SARS-Cov-2, COVID-19, vitamin C, quercetin, flavonoids, antiviral, Coronavirus, immunonutrition. In the last decades, several anticancer properties of quercetin have been described, such as cell signaling, pro-apoptotic, anti-proliferative and anti-oxidant effects, growth suppression. In nature, it exists in various forms in different plants and can be found as either quercetin aglycone or derivatives, while the most abundant In vitro studies investigating potential prophylactic compounds against SARS-CoV demonstrated that quercetin inhibited viral entry into simian Vero E6 cells and had the potential to inhibit viral replication. Introduction Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection causes coronavirus disease 2019 (COVID-19) and can be associated with serious complications, including acute respiratory distress syndrome. 7 Day Customer Support Live Chat; 1-800-537-9910; USD. It is acknowledged for its anti-inflammatory, antioxidative, and anti-viral/microbial properties which could be advantageous in managing Chemical structure of quercetin. This systematic review aimed to investigate the efficacy of supplemental curcumin treatment on clinical outcomes and inflammation-relate Hematological parameters. 2. Pure Despite the ongoing vaccination efforts, there is still an urgent need for safe and effective treatments to help curb the debilitating effects of COVID-19 disease. Since all of these compounds can reduce blood clotting, patients should be counseled and monitored for bleeding complications, including easy bruising Among the flavonoids in the human diet, quercetin is one of the most important. In the middle of this ongoing pandemic, we investigated the possible treatment benefits of quercetin in mild to moderately symptomatic COVID-19 outpatients in a randomized clinical trial with an aim that quercetin is safe, cheap, and Quercetin inhibited SARS-CoV-2 replication in Vero E6 cells and Caco-2 cells in a concentration-dependent manner with a half inhibitory concentration (IC50) of 166. Antioxidants and antihistamine properties. The highest concentration of bromelain was identified in the blood one hour after administration . $38. The present review highlights the main functions of a flavonoid, quercetin.
