How to Get the Most Out of Quercetin

What is Quercetin and what are its benefits?

Quercetin belongs to a group of plant pigments called flavonoids that give many fruits, flowers, and vegetables their colors. (1)

Flavonoids, such as Quercetin, are antioxidants. They scavenge particles in the body known as free radicals which damage cell membranes, tamper with DNA, and even cause cell death. Antioxidants can neutralize these free radicals hence they are very valuable. They may reduce or even help prevent some of the damage free radicals can cause.

Quercetin may help protect against heart disease and cancer. Quercetin can also help stabilize the cells that release histamine in the body and thereby have an anti-inflammatory and antihistamine effect. This can be a great natural remedy for Hayfever sufferers.

Quercetin dosage and timing

Often taken as a natural alternative to allergy medicine, Quercetin supplements typically come in capsule form, but are also available as liquid, powder or even gummies. If you want a dietary supplement that's potent and loaded with high-quality ingredients, there are a lot of options in the market.

Common oral dosages are 500 milligrams taken once or twice a day. People have also used lower dosages as well. However, optimal doses of Quercetin have not been established for any particular condition.

For children and adults, you would dose 30-60 minutes before bedtime. You should try to avoid giving it during the day as it can interrupt the hormone cycle. You can work with your doctor on doses higher than these. (2)

Food sources of Quercetin

Quercetin is abundant in nature and foods. People typically get between 5 and 40 milligrams a day from food. But if you eat lots of fruits and vegetables, you can get as much as 500 milligrams daily. (3)

For example, think "Quercetin" the next time you pour a glass of red wine, bite into a crunchy apple, treat yourself to some berries, slice an onion, or sip a cup of green tea. Other vegetables that have high amounts of quercetin include:

  • Kale
  • Tomatoes
  • Broccoli
  • Raw Asparagus
  • Capers
  • Red Raw Onion
  • Nuts and Seeds
  • Olive Oil
  • Red Grapes
  • Cherries

  • American elder
  • St. John's wort

The Difference Between regular Quercetin and Quercetin Dihydrate

Take Quercetin with Zinc

Zinc is vital for immune system function.  Zinc controls immune system messaging within the cells and is also an anti-oxidant (prevents cell damage) and is anti-inflammatory.  In cellular lab cultures, zinc has been shown to stop viral reproduction in minutes.  One study showed that zinc inhibited SARS coronavirus in test tubes. For zinc to work effectively in the body to boost immune system function, zinc has to be pushed into the cells which would require an ionophore.

An ionophore is a substance that transports particles across the cell wall barrier into the center of the cell.  The center of the cell is where zinc needs to be to have the immune system effect. Viruses reproduce in the center of the cells. Zinc needs to be in the center of the cell to stop viral reproduction. An all-natural zinc ionophore is Quercetin. The major benefit of taking Quercetin with zinc is that the Quercetin will push the zinc into the center of the cell where the zinc can stop the virus from reproducing.Think Of Zinc as the bullet and Quercetin as the gun.
