VERIFIABLE SCIENCE
Quercetin UltraSorb contains the patented
QuerceFit® quercetin-phospholipid complex for
enhanced 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 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.
