Science & Research:
Quercetin UltraSorb contains the patented QuerceFit® quercetin-phospholipid complex forenhanced absorption and bioavailability. The proprietary phytosome technology combines quercetin from Sophora japonica flower extract and phospholipids from sunflower in a 1:1 ratio, promoting resistance to degradation in the digestive tract and efficient absorption across membranes. A randomized crossover human pharmacokinetic study compared QuerceFit® with regular quercetin and found the phytosome improved the bioavailability of quercetin by 20-fold.1 Quercetin is a polyphenolic flavonoid known to exhibit cellular and immune-moderating activity. Research suggests that quercetin acts as a SIRT1 inducer to promote cellular regulation and autophagy, the natural process of degradation and recycling of cellular components to promote renewal.2, 3 It also increases the body's antioxidant capacity in part by regulating levels of glutathione.4, 5 In a pilot trial involving adults, supplementation for 30 days with 250 mg or 500 mg Quercetin Phytosome™ (QuerceFit®) quercetin phytosome supported antioxidant defenses and helped support respiratory function and nasal comfort.6 Preliminary research suggests that quercetin helps to stabilize mast cells and moderate the release of immune mediators.7-9
