Quercetin Powder

The biological properties of quercetin include antioxidant, anti-inflammatory, antibacterial, antiviral, free radical scavenging, and immune-modulating activities. These characteristics form the basis for potential benefits to overall health and disease resistance. Food sources of quercetin include broccoli, asparagus, green onions, bell peppers, tomatoes, red lettuce, as well as apples, strawberries, grapes, blueberries, cranberries, and blackcurrants.

In medical research, quercetin has been found to have multiple effects, including:

1. Assisting in the treatment of COVID-19, when used in combination with standard treatment, it helps to improve clinical outcomes and reduce disease severity.

2. Regulating blood pressure, with quercetin supplementation showing blood pressure-lowering effects, especially when the daily dose is greater than 500 mg and the duration of use is more than 8 weeks.

3. Possibly helping to protect cells, promote cell repair, and assist cells in self-protection to avoid damage or infection.

4. Having antioxidant effects, potentially strengthening the body's enzymatic antioxidant system to provide assistance to the body.

5. Possibly helping to reduce inflammation by controlling the production and release of inflammatory mediators.

6. Possessing potential anti-cancer effects, inhibiting the growth of cancer cells and inducing cell death.

7. Possibly reducing the risk of chronic brain diseases, such as Alzheimer's and dementia.

These potential health benefits of quercetin have made it a focus of scientific research, especially in terms of enhancing the resistance of the respiratory system and the antiviral effects of zinc. However, despite the promising benefits of quercetin, more human studies are needed to further verify these effects.
