Pure Encapsulations® Quercetin UltraSorb® – Advanced Cellular & Immune Support

With bioavailable Quercetin Phytosome™ (QuerceFit®) for enhanced-absorption cellular,
immune and cardiovascular support.

Wondering if Quercetin Is Right for You?

If you’ve tried quercetin before and didn’t notice much difference, absorption may have been the missing piece. Pure Encapsulations® Quercetin UltraSorb® is formulated specifically to solve that problem, delivering quercetin in a form the body can actually absorb and use.

Why Pure Encapsulations® Quercetin UltraSorb® Works Differently

Quercetin UltraSorb® uses the patented QuerceFit® quercetin-phospholipid complex, a clinically studied phytosome technology designed to dramatically improve bioavailability. By binding quercetin from Sophora japonica flower extract with sunflower-derived phospholipids in a precise 1:1 ratio, this structure protects quercetin from digestive breakdown and allows it to cross cell membranes efficiently.

In human research, this phytosome form demonstrated up to 20-times greater bioavailability compared to standard quercetin, helping ensure the quercetin you take is the quercetin your body can actually use.

What Quercetin Supports in the Body

Quercetin is a polyphenolic flavonoid known for supporting immune balance, antioxidant protection, and cellular resilience. Research shows it acts as a SIRT1 activator, helping regulate cellular signalling and support autophagy — the body’s natural process of cellular renewal and recycling. It also supports the body’s antioxidant defences by helping regulate glutathione, one of the body’s most critical internal antioxidants.

Clinical Studies

In clinical research, adults supplementing with bioavailable Quercetin Phytosome™ for 30 days experienced support for antioxidant defences, respiratory function, and nasal comfort. Emerging research also suggests quercetin helps stabilise mast cells and gently moderate the release of immune mediators, supporting a balanced immune response.

How Practitioners Use Quercetin UltraSorb®

Practitioners choose Quercetin UltraSorb® when they want predictable absorption and consistent outcomes. It is commonly used to support immune and respiratory health, antioxidant capacity, histamine balance, and cellular regulation, particularly in individuals who have not responded well to standard quercetin due to poor absorption.

In practice, quercetin is rarely used in isolation. It is often layered into protocols designed to support periods of increased immune demand, seasonal challenges, and longer-term cellular and longevity pathways.

Is Quercetin UltraSorb Suitable for Daily Use?

Yes. Quercetin UltraSorb® is designed for daily use and is well tolerated when taken as directed. It is free from common allergens and unnecessary additives, making it suitable for sensitive individuals. Many people notice improvements in immune or respiratory comfort within a few weeks, though individual responses vary.

A Word from Sara Banta, CEO/Founder of Accelerated Health Products

This is quercetin done properly — highly absorbable, clinically validated, and formulated to deliver meaningful physiological support rather than just another ingredient on a label.
