Quercetin

Quercetin was initially found to provide broad-spectrum protection against SARS coronavirus in the aftermath of the SARS epidemic that broke out across 26 countries in 2003.^1,2,3 Now, some doctors are advocating its use against SARS-CoV-2, in combination with vitamin C, noting that the two have synergistic effects.

Incidentally, ascorbic acid (vitamin C) and the bioflavonoid quercetin (originally labeled vitamin P) were both discovered by the same scientist — Nobel prize winner Albert Szent-Györgyi.^4,5 Quercetin’s antiviral capacity has been attributed to five main mechanisms of action:

1. Inhibiting the virus’ ability to infect cells by transporting zinc across cellular membranes
2. Inhibiting replication of already infected cells
3. Reducing infected cells’ resistance to treatment with antiviral medication
4. Inhibiting platelet aggregation — and many COVID-19 patients suffer abnormal blood clotting
5. Promoting SIRT2, thereby inhibiting the NLRP3 inflammasome assembly involved with COVID-19 infection 

Protect Your Heart & Overall Health*:

Quercetin is one of the most well-known, non-citrus bioflavonoids, intended to provide antioxidant activity and nutrition support that helps support heart and overall health.* Your body cannot manufacture bioflavonoids, so if you don’t get enough through your diet, you can get its benefits through a supplement like Solaray™ Quercetin, which has been shown to support healthy levels of histamine and support immune health.* Solaray Quercetin to your rescue!

Health Benefits Galore!:

Quercetin is a well-known flavonoid found in many fruits, vegetables, leaves and grains, and its strong antioxidant properties have been shown to have noticeable benefits to your overall health.* Acting as an antioxidant, Solaray Quercetin reduces damage by free radicals, protecting your immune system.* It also supports a healthy inflammation response.* The list of benefits goes on, as Quercetin has been shown to support healthy blood pressure already within normal range, protect your body from stress reactions, promote healthy skin, and support your cardiovascular health.*

Cardiovascular and Blood-Pressure Support:

Studies have shown that flavonoids – and Quercetin, in particular – promotes your cardiovascular health.* In addition to cardiovascular support, Solaray Quercetin can help maintain healthy blood pressure naturally.* One randomized, double-blind, placebo-controlled study showed that participants who used a Quercetin supplement experienced stabilization in systolic, diastolic and average arterial pressure compared to those who took a placebo.

Protect Your Body from Stress:

When your body gets stressed, it produces cortisol, which is a hormone that produces a “flight-or-fight” response. This is normal, but when your stress is high and prolonged, cortisol can break down proteins. Solaray Quercetin supports your stress response by promoting healthy levels of cortisol.*
