There are strong causes to suspect quercetin may be efficient towards SARS-CoV-2, the virus that causes COVID-19 illness.
This antioxidant, found in many foods, could boost your immune health.
Quercetin (Que) and its derivatives are naturally occurring phytochemicals with promising bioactive effects. The antidiabetic, anti-inflammatory, antioxidant, antimicrobial, anti-Alzheimer’s, antiarthritic, cardiovascular, and wound-healing effects of Que have been extensively investigated, as well as its anticancer activity against different cancer cell lines has been recently reported.
Bioavailability-related drug-delivery systems of Que have also been markedly exploited, and Que nanoparticles appear as a promising platform to enhance their bioavailability. The present review aims to provide a brief overview of the therapeutic effects, new insights, and upcoming perspectives of Que.
Quercetin is one of the most abundant flavonoids present in our food supply, found in high amounts in onions, kale and apples. It is well-known for many things, including its anti-allergy properties, anti-cancer effects, and as an antioxidant. But did you know that it can heal leaky gut, too?
Quercetin is both a flavonoid and a flavonol. There are different forms of quercetin which is something that becomes important as we move through interpreting the research on quercetin.
Parallels drawn with early data on hydroxychloroquine.
Before we dig deep into all the benefits quercetin boasts, it’s helpful to know what the heck it actually is. Dr. Lipman explains that quercetin is a type of polyphenol, which are micronutrients with antioxidant properties found in plants. Some foods that have this particular type of polyphenol are apples, onion, raspberries, red grapes, and cherries.
Quercetin has lots of benefits, but Dr. Lipman is most excited about its connection with longevity.
Flavonols, found in fruits and vegetables, were tied to a lower risk of Alzheimer’s disease.
Onions belong to the allium family of plants, which includes garlic and leeks. These vegetables have characteristic pungent flavours and some medicinal properties.
I am generally very suspicious of claims made on behalf of dietary supplements, but in light of a possible connection to COVID-19, I am keeping an eye on evolving information about quercetin.
Quercetin is popular because of how dynamic and versatile it is, including its wide array of benefits. Like other antioxidants, quercetin neutralizes free radicals that damage cell membranes, tamper with DNA, and even cause cell death.
