Quercetin’s effectiveness depends on how well your body can absorb and use it—a process called bioavailability. When you take quercetin, it embarks on a three-stage journey through your body: absorption, metabolism, and elimination.
Absorption
Not all quercetin is created equal when it comes to absorption. The form matters significantly. Quercetin glycosides (found naturally in onions) are absorbed much better than pure quercetin. This happens because glycosides can use special transporters in your small intestine—think of them as express lanes that help quercetin enter your bloodstream more efficiently.
Metabolisation
Once in your small intestine, enzymes called beta-glucosidases help break down quercetin compounds, making them easier to absorb. After absorption, your body transforms quercetin through several processes (methylation, sulfation, and glucuronidation) that occur in different organs. These transformations create active metabolites that deliver quercetin’s benefits throughout your body.
Elimination
Depending on how much quercetin you consume, these beneficial compounds accumulate in various organs where they’re needed most. Your body naturally eliminates quercetin metabolites over time, with excretion rates directly related to your intake levels.
Our liposomal delivery system addresses the primary challenge of poor absorption, ensuring you receive maximum benefits from this powerful flavonoid.

What is a Liposome?
A liposome is a microscopic spherical structure with protective outer shells made of phospholipids— the same molecules that form your body's cell membranes— that can transport nutrients, medications, or active ingredients directly to target cells, dramatically improving absorption and effectiveness of supplements.
Why Standard Supplements Fall Short
Traditional supplements face a fundamental challenge: surviving the harsh digestive environment to reach your bloodstream. Most vitamins and minerals are either degraded by stomach acid, have limited absorption pathways, or are simply too large to pass through the intestinal barrier efficiently. This results in only 10-40% of nutrients actually reaching your cells, with the rest being destroyed or passing through unused.
The Liposomal Solution: Nature-Inspired Delivery
Our Optimcell® liposomal delivery system solves this problem using biomimetic encapsulation—mimicking nature's own cellular design. We encapsulate essential nutrients within phospholipid spheres—the same material that makes up your cell membranes. This protective barrier:
- Shields nutrients from harsh digestive enzymes and stomach acid
- Facilitates transport through the intestinal wall
- Delivers nutrients directly to cells where they're needed
- Increases bioavailability by up to 90% compared to standard supplements

"The phospholipid encapsulation method used in liposomal delivery represents a significant advancement in nutrient delivery technology, addressing the longstanding issue of supplement bioavailability." — Dr. Sarah Johnson, Nutritional Biochemistry Researcher
The Science Behind Our Formula
Quercetin is a flavonoid with powerful antioxidant properties that humans can benefit from through diet and supplementation. Our Optimcell® Liposomal Quercetin formula addresses the key limitations of traditional supplements through advanced scientific formulation.
Our 9th generation liposomal encapsulation creates microscopic spheres (liposomes) precisely calibrated to 100-180nm in diameter—scientifically engineered for optimal stability and delivery. Each liposome consists of a phospholipid bilayer with hydrophilic (water-loving) heads and hydrophobic (water-repelling) tails arranged in a specific orientation.
This unique structure allows our liposomes to:
- Encapsulate both quercetin and vitamin C in different regions of the liposome
- Protect nutrients through the acidic environment of the stomach (pH 1.5-3.5)
- Merge directly with cell membranes due to their similar phospholipid composition
- Release nutrients directly into the cell rather than requiring active transport mechanisms
A 2023 comparative study showed liposomal quercetin achieved 8x higher blood concentration than standard quercetin supplements, demonstrating the dramatic improvement in bioavailability our encapsulation provides.
The Science of Superior Delivery
Liposomal Delivery System
Studies show that liposomal vitamin has up to 8x higher bioavailability compared to standard oral supplements. Our proprietary liposomal encapsulation applies this same principle to this powerful flavonoid, significantly enhancing absorption and cellular delivery while protecting it from digestive degradation.
The effectiveness of quercetin supplementation depends not just on the amount consumed, but on how much actually reaches your cells. Our liposomal delivery system addresses the primary limitations of traditional quercetin supplements:
Absorption Barrier Bypass
Conventional quercetin is limited by intestinal absorption capacity, while our liposomes enable transport through the intestinal membrane without relying on specific transporters.
Reduced Metabolism
Standard quercetin is rapidly metabolised when blood concentrations rise, but our liposomal formulation maintains lower peak blood concentrations while delivering more quercetin to tissues.
Cellular Penetration
The phospholipid encapsulation allows for direct fusion with cell membranes, delivering quercetin directly into cells.
“Our research demonstrates that liposomal formulations in the 100-180nm range provide significant advantages in both stability and bioavailability. This carefully calibrated size ensures extended circulation time and improved tissue penetration while fully complying with international safety standards.” — Professor Michael Carrington, Pharmaceutical Biochemistry
Prolonged Activity
Our liposomal delivery system creates a time-release effect, providing sustained quercetin availability throughout the day.
Through these advanced delivery mechanisms, our Quercetin supplements provide superior bioavailability, enhanced cellular uptake, and more consistent results than standard Quercetin formulations.
