Quercetin-PS, 60 capsules

One of the most important and thoroughly investigated bioflavonoids is quercetin

It is found in various foods, including apples, berries, cabbage and onions. Quercetin is a flavonol that protects plants against insect infestation and microorganisms, among other things. Quercetin in food is glycosidic (bound to sugar). Quercetin partially loses its effect at high temperatures, whether through storage, cooking or peeling. To increase your daily intake of quercetin, it can be useful to take a supplement. Like other bioflavonoids, quercetin is known to be poorly absorbed by the body due to its low solubility in water (and therefore also in aqueous digestive juices). Studies show that quercetin in a homogeneous mixture with phosphatidylcholine (in the phytosomal form) has up to 20 times higher absorption and bioavailability compared to pure quercetin.

Optimised absorption thanks to Phytosome® technology

Quercetin-PS provides quercetin from a natural source, derived from the flowers of the honey tree (Sophora japonica). The patented Phytosome® technology of the Italian manufacturer Indena has significantly improved the absorption and bioavailability of quercetin in Quercetin-PS. The term "phytosome" is composed of the Greek words "phuton" (plant) and "soma" (body). The patented manufacturing process reduces the natural clumping of certain poorly absorbable phytonutrients such as quercetin and combines them with phospholipids (fosfatidylcholine) from sunflower lecithin. The active ingredients are not encapsulated (as in liposomes), but a homogeneous mixture of small, easily absorbable particles is created. It is true that bioflavonoids (such as quercetin) have a natural affinity for phospholipids. This results in the formation of phytosomes in which the bioflavonoids adhere to the phospholipids. Cell membranes (such as those of small intestinal cells) are also made up of a phospholipid bilayer. This enables these phytosomes to effectively penetrate the intestinal wall and transport the active ingredients into the bloodstream. Studies have demonstrated that the absorption and bioavailability of quercetin is increased by a factor of 10 to 20 by this Phytosome® technology.

Unlike liposome technology, the active ingredient in a liposome is located inside a bead surrounded by a double layer of phospholipids. Phytosome® technology offers a truly homogeneous mixture without the active ingredient being encapsulated. For this reason, the phospholipids required are significantly less compared to liposomes.
