Uses For Isoquercetin w/Bioperine ®

Cardiovascular Health:

Quercetin promotes cardiovascular health by enhancing antioxidant defenses as well as capillary strength and integrity. Research suggests that it may also maintain healthy glucose metabolism and beta cell function.*

Immune Health:

Quercetin inhibits the synthesis of enzymes necessary for the release and degranulation of histamine. An in vitro study performed on neutrophils reported that quercetin mediated beta-glucuronidase and lysozyme release, as well as significantly moderated arachidonic acid release from cell membranes.*

Cellular Support:

An animal study indicated that quercetin supported prostate cell health by moderating receptor function at the transcription level. Additionally, in vitro studies have reported that this powerful flavonoid may be supportive of colon and breast cell health.*

What Is The Source?

Isoquercetin is derived from Fava d’anta tree ( Dimorphandra mollis ) pods and Cat’s claw ( Uncaria tomentosa ) leaves. Rutin is sourced from Fava d’anta tree ( Dimorphandra mollis ) pods. Bioperine ® black pepper extract is derived from Piper nigrum fruit and standardized to contain 95% piperine.
