Quercetins - Quercetin(s), DHQ
Flavonol from the flavonoid group of polyphenols, with antioxidant properties. It is found in many fruits, vegetables, leaves, seeds, and grains.
Quercetin is the aglycone form of a number of other flavonoid glycosides, such as rutin and quercitrin. Myricetin is structurally similar to fisetin, luteolin, and quercetin and is reported to have many of the same functions as these other members of the flavonol class of flavonoids. It is a potent antioxidant that has shown beneficial properties in supporting cardiovascular health and other metabolic problems such as diabetes. Myricetin can also inhibit the intestinal sugar transporter GLUT2 which may be helpful in controlling healthy blood sugar levels. Based on in vitro data this flavonoid may also protect cells from UV light by inducing apoptosis (cellular death) of those cells damaged by the radiation.
Taxifolin (refers as not mutagenic and less toxic than the related compound quercetin) correspond to the unique dihydroquercetin, when dihydroquercetins (with an 's') usually refers to the whole class of this flavonoids group.
