Vitals Quercetin-PSQuercetin is one of the most important and best-researched bioflavonoids. It occurs naturally in various foods, including apples, berries, brassicas, and onions. Quercetin belongs to the sub-group of flavonols, which, among other things, protect plants from damage by insects or microorganisms. In food, quercetin is present in the glycoside form (bound to a sugar). Storage at higher temperatures, cooking, or peeling can lead to a partial loss of quercetin. A dietary supplement with quercetin can therefore be useful to increase daily intake. Like other bioflavonoids, quercetin is known to be very poorly absorbed by the body due to its low solubility in water (and thus in aqueous digestive juices). Research shows that quercetin in a homogeneous mixture with phosphatidylcholine (in so-called phytosomal form) has up to 20 times better absorption and bioavailability than pure quercetin.
Improved absorption through Phytosome® technology
Quercetin-PS contains quercetin from a natural source. It is extracted from the flowers of the Japanese pagoda tree (Sophora japonica). The absorption and bioavailability of quercetin in Quercetin-PS has been greatly improved by the application of the patented Phytosome® technology from the Italian producer Indena. The term Phytosome comes from the Greek words phuton (plant) and soma (body). During the patented production process, the natural clumping of specific, poorly absorbable phytonutrients (such as quercetin) is limited, and these are mixed with phospholipids (phosphatidylcholine) from sunflower lecithin. The active ingredients are not encapsulated (as in liposomes), but a homogeneous mixture of small, well-absorbable particles is formed. Bioflavonoids (such as quercetin) have a natural affinity for phospholipids. The result is the formation of phytosomes, where the bioflavonoids attach to the phospholipids. In this way, they are absorbed extra well. Cell membranes (such as those of cells in the small intestine) themselves also consist of a phospholipid bilayer, so these phytosomes can excellent pass through the intestinal wall and the active ingredients can be well absorbed into the circulation. Studies have shown that the absorption and bioavailability of quercetin is 10-20 times better due to this Phytosome® technology.
Different from liposome technology
In a liposome, the active substance is located in the middle of a sphere with a double layer of phospholipids. With Phytosome® technology, it is truly a homogeneous mixture and the active substance is not encapsulated. This means you need much fewer phospholipids than with liposomes.
