Product Description
L-Aspartate Zinc is a zinc salt of L-aspartic acid, combining zinc with an amino acid component in a nutritional ingredient form. It is used primarily in dietary supplement and nutritional formulations where formulators seek a zinc-containing ingredient with defined composition, controlled purity, and convenient bulk handling.
This ingredient belongs to the Nutritional Ingredients category, specifically amino acid and mineral-related nutritional materials. Its value in B2B formulation lies in combining the nutritional relevance of zinc with the L-aspartate form, allowing product developers to select it according to formulation design, specification requirements, dosage form, and target-market regulations.
L-Aspartate Zinc is a zinc compound associated with L-aspartic acid. L-aspartate is the naturally occurring L-isomer of aspartic acid, an amino acid used in nutritional ingredient systems. Zinc is an essential mineral involved in numerous normal physiological functions, including normal enzyme activity and cellular processes.
For commercial sourcing, the exact specification should distinguish the chemical identity of the material from the elemental zinc contribution. Buyers should review the supplier specification and COA for assay, elemental zinc content, identity, moisture, heavy metals, microbiological parameters, and other applicable quality attributes.
| Item | Specification |
|---|---|
| Product Name | L-Aspartate Zinc |
| Category | Nutritional Ingredients; Amino Acid and Mineral Ingredient |
| CAS Number | Not assigned consistently across commercial zinc L-aspartate specifications; confirm against the exact chemical form supplied |
| Molecular Formula | Commercial zinc L-aspartate may be represented by different hydration or stoichiometric forms; specification should state the exact form |
| Molecular Weight | Depends on the stated stoichiometric and hydration form |
| Appearance | Typically a white to off-white powder |
| Assay / Grade | Food or nutritional grade; assay and elemental zinc specification depend on the defined chemical form |
| Identification | Identity testing according to the applicable specification and analytical method |
| Test Method | Applicable validated chemical, elemental, or chromatographic methods according to the specification |
| Particle Size | Customizable to formulation and processing requirements |
| Heavy Metals | Controlled according to applicable food, nutritional, and target-market requirements |
| Microbiological Quality | Controlled according to applicable nutritional ingredient specifications |
| Moisture | Controlled according to product specification |
| Shelf Life | Commonly 24 months when stored under recommended conditions |
| Storage | Store in a cool, dry place, tightly closed and protected from direct sunlight and excessive moisture |
| Packaging | Commonly 1 kg or 5 kg aluminum foil bags and 25 kg fiber drums; custom packaging available |
L-Aspartate Zinc can be considered for a range of nutritional ingredient applications, subject to the regulatory requirements of the destination market and the intended finished-product dosage.
For L-Aspartate Zinc, the key procurement issue is not simply the nominal purity of the powder. Buyers should first establish the exact chemical form and then evaluate the corresponding elemental zinc content, because stoichiometry and hydration can affect molecular-weight calculations and the amount of zinc delivered per unit weight.
| Buyer Requirement | What to Check | Why It Matters |
|---|---|---|
| Mineral contribution | Elemental zinc specification and calculation basis | Determines the actual zinc contribution used in formulation and labeling calculations. |
| Chemical identity | Declared stoichiometric form, hydration status, and identity test | Prevents different zinc-aspartate forms from being treated as interchangeable materials. |
| Finished dosage form | Powder characteristics, particle size, flow, and compatibility with excipients | Helps determine suitability for tablets, capsules, sachets, or blended powders. |
| Incoming quality control | COA covering identity, assay, heavy metals, microbiology, moisture, and other agreed parameters | Provides the information needed for batch release and supplier qualification. |
| Target market | Applicable food or supplement ingredient requirements and permitted labeling claims | Regulatory requirements can differ between markets and should be reviewed before commercialization. |
A commercially useful L-Aspartate Zinc specification should provide more than a product name and nominal purity. Procurement teams can request a defined chemical specification, batch-level quality documentation, and packaging suited to the intended production scale.
Common bulk packaging includes 1 kg and 5 kg aluminum foil bags for smaller production or sampling requirements and 25 kg fiber drums for larger-volume procurement. Packaging formats can be customized according to handling, transport, filling, and private-label requirements.
L-Aspartate Zinc can be incorporated into customized nutritional formulations and finished supplement programs. OEM and private-label services may include formulation development, dosage-form selection, blending, capsule or tablet production, labeling, and customized packaging.
For formulation projects, buyers should provide the intended dosage form, target market, elemental zinc target, serving size, excipient requirements, packaging format, and applicable regulatory specifications. This information helps establish an appropriate raw-material specification before production.
Quality control for L-Aspartate Zinc should address both chemical identity and nutritional ingredient quality. Batch documentation can include:
Final acceptance criteria should follow the agreed product specification and the regulatory requirements applicable to the destination market.
Start with the exact chemical form and elemental zinc requirement rather than comparing nominal powder purity alone. Then review identity, assay, moisture, contaminant limits, particle characteristics, and the intended dosage form. The final specification should also align with the regulatory requirements of the target market.
A commercial buyer will typically review a COA together with the product specification, TDS, and SDS. Depending on the agreed specification, the COA may cover identity, assay, elemental zinc, heavy metals, microbiological parameters, moisture, and other quality attributes required for batch release.
Store the material in a cool, dry environment in tightly closed packaging, protected from direct sunlight and excessive moisture. Good warehouse practice should minimize humidity exposure during opening, sampling, weighing, and repacking to help maintain consistent powder quality.
Yes. Particle size can be customized to formulation and processing needs, while packaging can be adapted for sampling, pilot production, bulk manufacturing, or private-label applications. Exact requirements should be incorporated into the commercial specification before production.
L-Aspartate Zinc is a zinc-containing nutritional ingredient suited to supplement and nutritional formulations where the exact chemical form, elemental zinc contribution, quality parameters, and dosage-form requirements need to be clearly controlled. A well-defined specification and batch-level documentation support reliable formulation and procurement.
