product details

Nutritional Profile: Quercetin (Bioflavonoid)

Quercetin is a premier plant-derived bioflavonoid found in red onions, apples, and berries. It is globally recognized for its ability to stabilize mast cells and act as a natural antihistamine. Despite its potent biological activity, standard quercetin is hydrophobic and poorly absorbed by the human digestive tract, often requiring very high doses to be effective.

Our Liposomal delivery system redefines the efficacy of this flavonoid. By encapsulating quercetin in microscopic lipid spheres, we achieve superior water solubility and protect it from premature breakdown. This advanced formulation allows quercetin to bypass traditional absorption barriers, delivering its antioxidant and immune-modulating power directly to the cells with significantly enhanced bioavailability.

Superior Water Solubility Natural Antihistamine Immune Modulator Respiratory Support Senolytic Agent

In the functional ingredients market, "liposome" has become synonymous with premium formulation. However, a harsh reality is plaguing global procurement managers: You may be paying liposome prices for "phospholipid mixtures."

What is Liposomal Technology?

Liposomes are an advanced microscopic delivery system. Composed of a phospholipid bilayer, their structure is highly similar to human cell membranes.

High Bioavailability Targeted Release

Four Core Advantages of Liposomal Quercetin

1. Maximum Absorption Rate

Bypasses the low-solubility constraints of raw powder. The lipid-shell facilitates direct membrane fusion, significantly increasing the concentration of quercetin in the blood.

2. Natural Allergy Management

More effective at stabilizing mast cells than standard forms, providing rapid and sustained support against seasonal environmental triggers.

3. Synergistic Zinc Transport

Acts as a zinc ionophore. The liposomal delivery ensures both molecules reach the intracellular space effectively to support antiviral defense.

4. Optimized Water Dispersibility

Unlike standard yellow-staining, insoluble quercetin, our liposomal powder is fully dispersible, making it ideal for clean-label functional beverages and mixes.

Function

1. Antioxidant: Quercetin (the core active component in Sophora japonica extract) has strong free radical-scavenging ability, which reduces oxidative damage to cells and delays tissue aging.

2. Anti-inflammatory: It inhibits the release of pro-inflammatory mediators (e.g., histamine, prostaglandins), relieving inflammatory responses in the body.

3. Vascular Protection: It helps improve blood vessel elasticity, reduce capillary permeability, and support cardiovascular health.

4. Antibacterial & Antiviral: It exhibits inhibitory effects on certain pathogenic bacteria and viruses (e.g., influenza virus) by disrupting microbial cell structures.

5. Antihistamine: It alleviates allergic reactions (e.g., hay fever, skin itching) by blocking histamine receptors. 2. Applications

Application

1. Food & Beverage Industry: Used as a natural antioxidant or functional ingredient in health drinks, functional snacks, and fortified foods.

2. Pharmaceutical Industry: Applied in the R&D of drugs for treating cardiovascular diseases, inflammatory conditions, and allergic disorders..

3. Cosmetics Industry: Added to anti-aging, anti-inflammatory skin care products (e.g., serums, creams) to improve skin texture and soothe irritation.

4. Health Supplement Industry: Developed into capsules, tablets, or powders for daily antioxidant, vascular health, and anti-allergy support.
