Liposomal Zinc glycinate 80% — High Bioavailability Chelated Zinc Supplement

Product Overview

liposomal Zinc Glycinate 80% is a premium-grade dietary supplement ingredient delivering zinc bisglycinate in an advanced liposomal delivery system. Zinc bisglycinate, also known as zinc glycinate, is a fully reacted amino acid chelate in which a central zinc ion is covalently bonded to the alpha-amino and carboxylate groups of two glycine molecules. This chelation process results in the formation of two stable, five-membered heterocyclic rings—a structural feature fundamental to its enhanced bioavailability and tolerability.

Zinc is an essential trace mineral required for immune system function, DNA synthesis, protein production, wound healing, and numerous enzymatic reactions. However, conventional zinc supplements—particularly zinc sulfate and zinc oxide—exhibit variable bioavailability and frequently cause gastrointestinal discomfort, nausea, and a persistent metallic aftertaste. Zinc glycinate addresses these limitations through its chelated structure and amino acid transport pathway absorption, while liposomal encapsulation provides an additional layer of protection and delivery enhancement.

Why Liposomal Technology?

Zinc glycinate already offers superior bioavailability compared to inorganic zinc salts. A narrative review of clinical studies comparing the absorption and bioavailability of various chemical forms of zinc concluded that zinc glycinate and zinc gluconate are better absorbed than other forms of zinc, including zinc oxide and zinc picolinate.

Liposomal encapsulation further enhances its performance through a biomimetic phospholipid bilayer that protects the zinc-chelate complex during digestive transit and facilitates efficient cellular delivery.

Liposomal encapsulation provides four critical advantages:

1. Gastric Protection — The phospholipid bilayer shields the zinc-glycine chelate from gastric acid degradation and interaction with dietary inhibitors including phytates and tannins, preserving its intact structure until reaching optimal absorption sites in the small intestine.

2. Enhanced Cellular Uptake — liposomes fuse directly with intestinal cell membranes, facilitating efficient cellular delivery and bypassing traditional ion-channel absorption limits. In intestinal epithelial cell permeability simulation studies, liposomal zinc demonstrated bioavailability 16.8 times higher than conventional raw material zinc, with significantly improved absorption efficiency and effectiveness.

3. Superior Bioavailability — A human clinical study comparing various zinc supplementation forms found that liposomal zinc achieved up to 3.82 times higher bioavailability compared to non-liposomal zinc forms. A randomized crossover trial further demonstrated that zinc concentrations were significantly higher from 0 to 6 hours in the liposomal group compared to non-liposomal comparators.

4. Taste Improvement and GI Tolerance — Conventional zinc formulations are prone to metallic and astringent off-notes. In sensory experiments, liposomal zinc demonstrated a significantly milder taste profile in sourness, astringency, bitterness, metallic notes, and off-odors compared to zinc sulfate and conventional zinc glycinate. Liposomal encapsulation also minimizes direct contact between zinc and the gastrointestinal mucosa, reducing the risk of nausea and cramping.

Product Specifications

Key Features

• High Purity — Standardized to ≥80% zinc glycinate by HPLC, ensuring consistent active content and ≥20% elemental zinc.

• Fully Chelated Structure — Each zinc ion is bound to two glycine molecules, creating a stable ring-like chelate structure that protects zinc from dietary inhibitors.

• Superior Bioavailability — Clinical evidence demonstrates that zinc glycinate is better absorbed than zinc oxide, zinc picolinate, and other conventional forms.

• Liposomal Enhancement — Phospholipid bilayer encapsulation delivers 16.8× higher bioavailability compared to conventional zinc in cell permeability studies, with up to 3.82× higher bioavailability in human clinical research.

• Gentle on Digestion — Because zinc remains chelated through the gastric environment, it does not generate free zinc ions that cause gastrointestinal irritation. Ideal for individuals with sensitive stomachs.

• No Metallic Aftertaste — Liposomal encapsulation significantly reduces the metallic and astringent off-notes commonly associated with conventional zinc supplements.

• Non-Competitive Absorption — Does not compete with iron, copper, or calcium for absorption and is less likely to bind with dietary inhibitors.

• Water-Dispersible — Suitable for capsules, tablets, powder drink mixes, and functional beverages.

• Batch Traceability — Complete COA, HPLC chromatogram, FTIR identity confirmation, and elemental zinc assay data provided for each batch.

Application & Formulation Guidance

Recommended Dosage

Clinical guidelines and commercial products commonly recommend 8–11 mg of elemental zinc per day for maintenance in healthy adults, with the RDA established at 11 mg per day for adult men and 8 mg per day for adult women. For therapeutic support, 15–30 mg per day is commonly used. A typical dosing regimen of 1–2 capsules daily provides approximately 15–25 mg elemental zinc. Zinc glycinate can be taken with meals without the typical reduction in absorption seen with ionic zinc forms, offering greater flexibility in dosing. Co-supplementation with vitamin C further enhances immune support. Zinc supplementation should not exceed 40 mg per day without medical supervision.
