Quercetin That You Can Absorb

Vitauthority's Quercetin features a powerful patented Querecetin called Quercefit with clinical data to support immune health, contain anti-inflammatory benefits, and is a powerful antioxidant.

The best part?

In research, it’s been shown to be 20x better absorbed than unformulated quercetin.

Benefits of Quercetin*

Quercetin is a plant pigment (flavonoid). It's found in many plants and foods, such as red wine, onions, green tea, apples, and berries.

It has 3 unique benefits in our opinion that make quercetin a no-brainer to add to your supplement regimen:


Quercetin is a potent antioxidant, which means it fights the natural process of ‘oxidation’ that takes place over time as we age. Quercetin may help to neutralize the effect of free radicals, which negatively impact healthy cells like damaging cell membranes.


Quercefit® has been studied in sports nutrition by promoting a 11% better performance time in sprint triathlon as compared to baseline.


Quercetin stabilizes Mast cells that release histamine, the principal mediator of reactions to pollen and other allergies, making it a natural antihistamine.

It Only Helps If You Can Absorb It

Quercefit® then goes a step further by including ground breaking Phytosome® technology to help with absorption in the human body.

A phytosome is a compound created by complexing a plant extract with lecithin. Clinical studies have shown that a phytosome complex significantly improves the absorption of the plant extract and its effects on the body.

The result?

A 20-fold increase in blood quercetin levels thanks to Phytosome®. Which means more results for your goals.
