Vitals - Quercetine-PS - 60 capsules

What is Vitals Quercetine-PS?

Improved absorption through Phytosome® technology

Quercetin-PS contains quercetin from natural sources. It is extracted from the flowers of the honey tree (Sophora japonica). The uptake and bioavailability of quercetin in Quercetin-PS has been greatly improved by applying the patented Phytosome® technology from the Italian manufacturer Indena. The term Phytosome (or 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 substances are not encapsulated (as in liposomes), but a homogeneous mixture of small, easily absorbable particles is created. 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. After all, cell membranes (such as those of cells in the small intestine) themselves also consist of a phospholipid bilayer, so that these phytosomes can pass through the intestinal wall excellently and the active ingredients can be well absorbed into the circulation (see figure 1). Studies have shown that the absorption and bioavailability of quercetin is 10-20 times better with this Phytosome® technology. 

Different from liposome technology

In a liposome, the active substance is located in the center of a sphere with a double layer of phospholipids. The Phytosome® technology is really a homogeneous mixture and the active ingredient is not encapsulated. As a result, you need much less phospholipids than with liposomes.
