Quercetin UltraSorb
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®(300mg) with regular quercetin and found the phytosome improved the bioavailability of quercetin by 20-fold.
Dosing: 1 - 2 capsules a day after a meal.
