WHAT IS QUERCEFIT® QUERCETIN PHYTOSOME?

Quercefit® is Indena’s unique Phytosome® formulation of quercetin. Some ingredients—quercetin is one of them—are very poorly absorbed. Indena’s Phytosome® technology creates a quercetin phytosome complex using sunflower lecithin, resulting in dramatically enhanced bioavailability* [1]. The result, as Indena likes to say, is “Quercetin, made better.” But what is quercetin? Quercetin is a yellow plant pigment. Its name is derived from the Latin word for oak forest—quercetum—because it was originally identified in oaks. Quercetin is a flavonol, which is one of the polyphenol categories. Polyphenols play important roles in the plant kingdom. One of these roles is protecting plants from environmental stress such as pests and UV irradiation from the sun. Because of this role, they tend to concentrate in parts of the plant that come into more contact with the outside world. Red onions are one of the better food sources of quercetin. But the quercetin isn’t uniformly spread through red onions; it concentrates in the outer skins (which are usually thrown away when onions are peeled before use) and the part closest to the root. Capers may be the best dietary source of quercetin. 

 

NEUROHACKER’S QUERCEFIT® QUERCETIN PHYTOSOME SOURCING

Quercefit® is a sunflower lecithin formulation of quercetin (Quercetin Phytosome®) containing 34-42% quercetin obtained from flower buds of Sophora japonica L. 

Quercefit® has shown up to 20-fold more bioavailability than unformulated quercetin [1].

Quercefit® is a registered trademark of Indena S.p.A.

Quercefit® is non-GMO, gluten-free, and vegan. 


QUERCEFIT® QUERCETIN PHYTOSOME FORMULATING PRINCIPLES AND RATIONALE

We chose the recommended serving of Quercefit® taking into account several different factors. The primary factor was how quercetin in general, and Quercefit® specifically, are being dosed as a senolytic in clinical research. An example of this is a planned clinical trial (ClinicalTrials.gov identifier NCT04313634) which is using a similar intermittent administration protocol to what’s recommended for Qualia Senolytic. The trial is administering Quercefit® at 1000 mg daily for several days. Our recommended serving selection also took into account that Qualia Senolytic contains several other ingredients which share some cellular function mechanisms with quercetin.* We opted for a slightly lower recommended daily serving of Quercefit® (750 mg per dose) to account for the contributions being made by these other ingredients.
