Life Extension Bio Quercetin 30 capsules

Life Extension Bio Quercetin

Quercetin is a naturally occurring plant bioflavonoid from the polyphenol group. In a normal diet, it is mainly found in onions, apples, capers, black tea, cranberries, and red grapes. To give you an idea: one medium-sized apple contains approximately 4–10mg of quercetin, and a large onion about 35mg. It is one of the most common flavonoids in the human diet—and also one where the form of delivery is worth considering.
Phytosome is a patented technology in which the quercetin molecule binds to a phospholipid from sunflower seeds—the same type of substance that makes up cell membranes in the human body. This creates a complex that is absorbed in the intestine via a different pathway than free quercetin. In this form, quercetin exhibits up to 62× higher bioavailability than the same dose of standard quercetin. The practical result: 29mg of pure quercetin in a Bio Quercetin capsule corresponds to the level that a significantly higher dose of conventional quercetin would provide.
