About Quercetin Phytosome Quercefit Capsules

Quercetin Phytosome features the clinically studied Quercefit, a phytosome-enhanced form of quercetin that boosts bioavailability nearly 20-fold compared to standard quercetin. This flavonoid supports immune function through its zinc ionophore activity, helps regulate histamine levels, and promotes exercise performance and recovery.

Our Quercetin Phytosome Story

During the 2020 health crisis, quercetin gained widespread attention for its zinc ionophore properties and immune support benefits. However, standard quercetin suffers from poor bioavailability due to its water solubility limitations. While increasing dosage was one solution, we wanted to tackle this challenge with advanced formulation technology rather than simply throwing more milligrams at the problem.

Phytosome technology embeds quercetin particles within phospholipid spheres to dramatically improve absorption. This approach addresses quercetin's partition coefficient issues by creating smaller particle sizes while surrounding the quercetin with phospholipids that enhance its solubility profile. The result is Quercefit, a scientifically validated quercetin phytosome that delivers superior bioavailability, making each dose more effective at supporting your health goals.

Benefits

• Boosts Immune System: Quercetin acts as a zinc ionophore, shuttling zinc directly into cells where it can inhibit viral replication and enhance immune function throughout the body.
• Anti-Inflammatory Properties: Supports healthy histamine levels by inhibiting histamine release from mast cells, helping regulate the body's inflammatory response and potentially improving sleep quality.
• Regulates Oxidative Stress: Provides antioxidant protection while modulating NAD+ pathways by inhibiting CD38, an enzyme that normally degrades this crucial cellular energy molecule.
• Improves Endurance: Enhances exercise performance through AMPK activation, with studies showing triathlon athletes experienced faster sprint times and quicker recovery when supplemented with quercetin phytosome.

The phytosome delivery system embeds quercetin particles in phospholipids, overcoming quercetin's natural water solubility issues and poor partition coefficient. This formulation increases bioavailability nearly 20-fold compared to standard quercetin, ensuring your body can effectively utilize this flavonoid's wide-ranging benefits.

Quality and Standardization

• Quercefit Phytosome Technology: Our quercetin is formulated using the clinically studied Quercefit phytosome delivery system, which embeds quercetin particles within a phospholipid matrix to overcome its natural water solubility limitations.
• Bioavailability Enhancement: The phytosome formulation achieves nearly 20-fold greater bioavailability compared to standard quercetin by reducing particle size and improving the compound's partition coefficient (LogP) for enhanced absorption.
• Sophora Japonica Source: We source our quercetin from the flower buds of Sophora japonica, where this flavonoid naturally concentrates in its highest potency form for optimal therapeutic benefit.
• Third-Party Testing: Each batch undergoes rigorous purity and identity verification through our third-party labs to ensure consistent quality and potency in every capsule.
• Standardized Dosing: Each capsule provides precisely 250mg of Quercefit phytosome, delivering a therapeutically relevant dose based on clinical research while maintaining excellent tolerability profiles.

Mechanism of Action

• Zinc Ionophore Activity: Quercetin acts as a cellular transport facilitator for zinc ions, helping shuttle this essential mineral directly across cell membranes where it can inhibit viral replication and support immune cell function.
• Histamine Release Inhibition: The flavonoid directly blocks histamine release from mast cells through stabilization of cellular membranes, providing natural support for managing inflammatory responses and allergic reactions.
• AMPK Pathway Activation: Quercetin activates AMP-activated protein kinase (AMPK), a master metabolic regulator that enhances cellular energy production and may contribute to improved exercise endurance and recovery.
• CD38 Enzyme Inhibition: By inhibiting CD38, an enzyme that degrades NAD+, quercetin helps preserve cellular longevity pathways and supports mitochondrial energy metabolism throughout the body.
• Phospholipid Delivery System: The phytosome technology encapsulates quercetin within phospholipids that naturally integrate with cell membranes, dramatically improving absorption and bioavailability compared to standard quercetin formulations.

Overview of the Science

Quercetin phytosome represents a significant advancement in flavonoid supplementation, addressing the fundamental bioavailability challenges that have historically limited quercetin's therapeutic potential [1]. The phytosome delivery system embeds quercetin molecules within a phospholipid matrix, creating a lipid-compatible structure that dramatically enhances absorption across cellular membranes. This technology overcomes quercetin's poor water solubility and low partition coefficient, which typically prevent effective uptake in the gastrointestinal tract. Clinical research demonstrates that the phytosome formulation increases quercetin bioavailability by nearly 20-fold compared to standard quercetin extract, making previously therapeutic doses accessible through practical supplementation.

Beyond improved bioavailability, quercetin phytosome demonstrates unique effects on cellular metabolism and longevity pathways that distinguish it from other flavonoids. The compound activates AMPK (adenosine monophosphate-activated protein kinase), a master metabolic regulator that enhances cellular energy efficiency and promotes mitochondrial biogenesis. Additionally, quercetin inhibits CD38, an enzyme responsible for degrading NAD+, thereby supporting cellular energy production and DNA repair mechanisms. These metabolic effects complement quercetin's well-established antioxidant properties, creating a multifaceted approach to cellular health that extends beyond traditional inflammation management.

Ingredients

Quercetin Phytosome with Quercefit:

• Quercetin (from Sophora japonica flower bud extract)
• Formulated with Quercefit phytosome technology
• 250mg per capsule

The Quercefit phytosome formulation represents a breakthrough in addressing quercetin's fundamental absorption challenges. By embedding quercetin particles within phospholipid spheres, this advanced delivery system overcomes the flavonoid's poor water solubility and low partition coefficient (LogP) that typically limits bioavailability. The phospholipid matrix not only reduces particle size but also creates a lipid-friendly environment that dramatically improves quercetin's ability to cross cellular membranes. This sophisticated approach to nutritional supplements ensures that each 250mg dose delivers significantly more bioactive quercetin than conventional formulations, making it an ideal choice for those seeking maximum therapeutic potential from their anti oxidative stress supplements.
