Quercetin Phytosome is a formulation where quercetin is bound to phospholipids, typically derived from sunflower or soy lecithin, to enhance its bioavailability and absorption. | Quercetin Phytosome is a formulation where quercetin is bound to phospholipids, typically derived from sunflower or soy lecithin, to enhance its bioavailability and absorption. The elevant clinical study used Quercetin Phytosome consisting of quercetin and sunflower lecithin in a 1:1 weight ratio along with about a fifth part of food-grade excipients that are added to improve the physical state of the product and to standardize it to a HPLC-measured total quercetin content of about 40%. <ref>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6418071/</ref> | ||
In the clinical study ~20 fold increase bioavailability was measured compare to standard quercetin with equal doses. Given that Quercetin Phytosome contains ~40% and has a ~20 fold relative bioavailabilty, one can assume that the total bioavailability of standard quercetin is less than 2%. | |||
