Liposomal zinc lactate 80% — High Bioavailability Zinc Supplement

Product Overview

liposomal Zinc Lactate 80% is a premium-grade dietary supplement ingredient delivering zinc lactate in an advanced liposomal delivery system. Zinc lactate (CAS 16039-53-5), also known as zinc dilactate or zinc 2-hydroxypropanoate, is an organic zinc salt formed by the reaction of lactic acid with zinc oxide or zinc carbonate. It is chemically characterized by the molecular formula C₆H₁₀O₆Zn and a molecular weight of 243.53 g/mol. Zinc lactate occurs as a white, odorless, crystalline powder that is freely soluble in water (55 g/L) and slightly soluble in ethanol. It loses its water of crystallization at 100°C and has a melting point of approximately 280°C. Zinc lactate provides approximately 22.2% elemental zinc by weight, the highest zinc content among common organic zinc salts, making it one of the most concentrated and well-absorbed organic zinc forms available.

Zinc is an essential trace mineral present in all body tissues and fluids. As a component of over 200 enzymes, it is involved in more enzymatic reactions than any other mineral, affecting virtually all aspects of the immune system and playing essential roles in hormonal functions, skin and connective tissue metabolism, and sensory perception. Zinc lactate is widely utilized in pharmaceutical and nutraceutical formulations due to its high bioavailability, excellent water solubility, neutral taste profile, and superior gastrointestinal tolerability.

Why Liposomal Technology?

Zinc lactate already offers superior bioavailability compared to inorganic zinc salts, with a relative bioavailability of 35–50%, significantly better than zinc sulfate and zinc oxide. However, conventional zinc lactate formulations still face challenges related to gastrointestinal tolerability and the saturable nature of zinc absorption.

Liposomal encapsulation provides four critical advantages:

1. Superior Bioavailability — A liposomal zinc formulation developed by West Bengal Chemical Industries Ltd. using phosphatidylcholine as the lipid carrier demonstrated 3.82 times higher bioavailability compared to non-liposomal zinc. The liposomal zinc formulation exhibited a high encapsulation efficiency of 94.51% and maintained stability over six months (EE%: 94 ± 1%, assay: 20 ± 1%), with thermal stability tests showing minimal changes in EE% and assay values at room temperature and 105°C for 4 hours.

2. Enhanced Cellular Uptake — liposomes fuse directly with intestinal cell membranes, facilitating efficient cellular delivery via lipid-mediated pathways. The liposomal delivery system bypasses the saturable nature of carrier-mediated zinc transport, providing an alternative route of cellular entry. In a randomized crossover trial, zinc concentrations were significantly higher from 0 to 6 hours in the liposomal group compared to non-liposomal comparators.

3. Reduced Gastrointestinal Irritation — Liposomal encapsulation minimizes direct contact between zinc and the gastrointestinal mucosa, reducing the risk of nausea and cramping commonly associated with conventional zinc salts. Zinc lactate is already known for its excellent gastrointestinal tolerability, and liposomal encapsulation further enhances this advantage.

4. Neutral Taste Profile — Liposomal technology completely locks zinc ions inside the phospholipid layer, thoroughly shielding them from metallic odor. Zinc lactate itself has a neutral taste, making the liposomal formulation ideal for ready-to-eat powders, oral liquids, functional gummies, and oral care products.

Product Specifications

Key Features

• High Purity — Standardized to ≥80% zinc lactate, with elemental zinc content of 22.2% and assay of 97.0%–102.0% (USP/FCC).

• Liposomal Enhancement — Phospholipid bilayer encapsulation achieves 94.51% encapsulation efficiency and 3.82 times higher bioavailability compared to non-liposomal zinc, with stability maintained over six months.

• Highest Elemental Zinc Content — Zinc lactate contains approximately 22.2% elemental zinc, the highest among common organic zinc salts, making it a highly concentrated zinc source.

• Superior Bioavailability — Zinc lactate has a relative bioavailability of 35–50%, significantly better than inorganic zinc forms such as zinc sulfate and zinc oxide.

• Immune Function Support — Zinc supports many aspects of innate and acquired immunity and has anti-inflammatory and antioxidant effects. Clinical trial data support the value of zinc in reducing the duration and severity of symptoms of the common cold when administered within 24 hours of onset.

• Oral Care Applications — A controlled, clinical, double-blind study in 100 participants demonstrated that tablets containing 0.17 mg zinc in the form of zinc lactate and magnolia bark extract significantly reduced oral volatile sulfur-containing compounds (VSC) levels by 62% at eight minutes, 30% at one hour, and 18% at two hours, with statistically significant differences compared to control tablets (p < 0.001, p < 0.001, and p < 0.05, respectively).

• Gentle on the Stomach — Zinc lactate has excellent gastrointestinal tolerability and does not cause the nausea, cramping, or metallic aftertaste frequently associated with zinc sulfate and zinc oxide.

• Water-Dispersible — Freely soluble in water (55 g/L); suitable for capsules, tablets, powder drink mixes, functional beverages, and oral care formulations.

• Batch Traceability — Complete COA, HPLC chromatogram, and identity data provided for each batch.

Application & Formulation Guidance

Recommended Dosage

Clinical guidelines and commercial products commonly recommend 15–30 mg of elemental zinc per day from zinc lactate. For zinc lactate specifically, the human body's normal zinc requirements translated to zinc lactate are: 30–50 mg/day for individuals under 17 years, 50–75 mg/day for adults, 50–90 mg/day for pregnant women, and 75–110 mg/day for lactating women. The Tolerable Upper Intake Level (UL) for zinc is 40 mg per day for adults. Long-term intake of 25 mg or above may lead to anaemia and copper deficiency. For common cold support, zinc lozenges containing 10–13 mg of elemental zinc from zinc lactate are available, with research supporting administration within 24 hours of symptom onset. Liposomal formulations may allow for more efficient utilization of lower doses due to enhanced bioavailability.
