Quercetin: Benefits, Dosage, and Side Effects

Quercetin: Benefits, Dosage, and Side Effects

Quercetin is a well-researched flavonoid (plant pigment) with powerful antioxidant properties. It has numerous functions including anti-carcinogenic, anti-inflammatory, and antiviral activities.

The body can’t produce quercetin, making it an essential nutrient to consume through diet or supplements. It's also available in common herbal supplements such as ginkgo biloba and St. John’s wort.

Benefits of Quercetin

The primary benefits come from its antioxidant qualities, studies show. Free radicals in the body can cause chronic inflammation, which this supplement may help reduce and prevent.

Test-tube studies show it reduced inflammation in human cells (1). An even more extensive study was done with 50 women who took 500mg of quercetin over an 8-week period (2).

These women experienced much lessened early morning stiffness and pain, and after-activity pain.

There are a variety of other benefits quercetin may provide such as reduced allergy symptoms, potential anticancer effects, lowered risk of chronic brain disorders, and lower blood pressure.

These effects could be amplified when it is consumed with other select nutrients, or when taken as a supplement blend with specific ingredients.

Side Effects

Because this is a natural sourced supplement there are very few if any side effects. The worst you could expect while using it in regular doses is a headache, or upset stomach for a little while.

Because of this there really is no risk to trying out this supplement in order to improve many aspects of you life.

What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
