Product Description
Zinc Picolinate Powder is a nutritional ingredient consisting of zinc bound to picolinic acid, used as a source of zinc in dietary supplements and mineral formulations. For B2B buyers, it offers a defined ingredient for capsule, tablet, and premix development, with procurement decisions centered on elemental zinc content, compound assay, purity, and dosage-form compatibility.
Zinc Picolinate Powder is used in nutritional supplement formulations to provide zinc, an essential trace mineral involved in normal physiological functions, including immune function, protein synthesis, and DNA synthesis. Its picolinate form is selected by formulators seeking a specific zinc compound rather than an unspecified zinc source.
For commercial sourcing, the critical factors are chemical identity, compound purity, elemental zinc concentration, contaminant limits, and batch-to-batch consistency. A complete purchasing specification should distinguish the assay of zinc picolinate from the percentage of elemental zinc delivered by the ingredient.
Zinc Picolinate is a zinc salt of picolinic acid. The commonly referenced anhydrous compound has the molecular formula C12H8N2O4Zn and a molecular weight of approximately 309.59 g/mol. Its theoretical elemental zinc content is approximately 21.1% by weight, assuming the anhydrous compound with the stated molecular formula.
Zinc contributes to normal immune function, macronutrient metabolism, and the maintenance of normal skin. Zinc picolinate has been studied as a supplemental zinc source, but ingredient identity alone does not establish superior absorption or clinical outcomes compared with other zinc forms. Finished-product claims must follow the applicable regulations in the intended market.
Zinc Picolinate Powder is used in mineral supplements and multinutrient formulations. The amount included in a finished product should be calculated using verified elemental zinc content and the intended serving size, rather than treating the total ingredient mass as elemental zinc.
The ingredient can be incorporated into solid dosage forms using suitable blending and manufacturing procedures. Because zinc ingredients are often included at relatively low levels, formulators should evaluate blend uniformity, particle-size distribution, excipient compatibility, and segregation risk.
Zinc Picolinate may be incorporated into mineral premixes and selected nutritional powder blends. Premix design should account for the concentration of zinc, differences in particle size and bulk density, and the ability of the mixing process to distribute the ingredient consistently.
For contract manufacturing projects, Zinc Picolinate can be considered for customized capsule, tablet, and powder products. Selection should be based on the target market, desired elemental zinc amount per serving, finished-product specifications, and applicable labeling requirements.

Specification note: Molecular characteristics and theoretical elemental zinc content refer to the stated anhydrous compound. Commercial assay results, moisture, impurity limits, shelf life, and acceptance criteria must be established in the approved product specification and supported by the relevant batch documentation. If a commercial material has a different hydration state or composition, its specification and calculations must be adjusted accordingly.
For Zinc Picolinate Powder, the key procurement distinction is between the percentage of zinc picolinate in the raw material and the percentage of elemental zinc it supplies. These figures are not interchangeable. This distinction directly affects supplement formulation calculations, label declarations, and the quantity of ingredient required per production batch.
| Procurement Check | Why It Matters | What to Verify |
|---|---|---|
| Compound Assay | Indicates the measured proportion of zinc picolinate under the defined test method. | Assay method, calculation basis, acceptance range, and batch result. |
| Elemental Zinc Content | Determines the actual zinc contribution used for nutritional calculations. | Direct elemental analysis, reporting basis, and batch-specific result. |
| Identity Confirmation | Helps verify that the supplied material matches the intended ingredient. | Validated identity method and relevant reference standard. |
| Impurity Profile | Supports raw-material qualification for the intended nutritional use. | Heavy metals, relevant impurities, and residual solvents where applicable. |
| Physical Properties | Influence blending, flow, segregation, and finished dosage-unit consistency. | Appearance, moisture, and particle-size distribution where relevant. |
| Batch Documentation | Allows quality teams to compare deliveries against approved requirements. | COA, specification, test methods, lot traceability, and applicable stability information. |
Formulation example: Based on the theoretical elemental zinc content of approximately 21.1%, 100 mg of pure anhydrous zinc picolinate corresponds to about 21.1 mg of elemental zinc. This is a theoretical calculation, not a batch assay result. Actual formulation calculations should use the verified elemental zinc content of the supplied material and the applicable regulatory limits.
Practical sourcing advice: Request both compound assay and elemental zinc results when qualifying a supplier. A high compound assay does not independently confirm the exact elemental zinc contribution if the material's hydration state, composition, or reporting basis differs. Align the supplier's analytical methods and reporting basis with the finished-product specification and incoming quality procedures.
For professional buyers, reliable sourcing depends on clear specifications, appropriate testing, and documentation that matches the intended use. The following supply considerations support efficient raw-material qualification and repeat procurement.
Common bulk packaging includes 1 kg and 5 kg aluminum foil bags for smaller production runs and 25 kg fiber drums for larger-volume procurement. Suitable packaging should protect the material from moisture and contamination during storage and transport. Other pack sizes and configurations can be customized to suit manufacturing, logistics, and handling requirements.
Store Zinc Picolinate Powder in tightly sealed packaging in a cool, dry environment away from direct sunlight and excessive heat. After opening, reseal promptly and follow the storage conditions stated in the approved product documentation.
OEM and private-label services can support nutritional products containing Zinc Picolinate, including customized capsule, tablet, and powder formulations. Project scope may include ingredient selection, formulation development, dosage-form production, packaging, and label customization.
Before production, define the intended market, target elemental zinc amount per serving, ingredient acceptance criteria, finished-product testing requirements, packaging format, and label claims. Final formulations and labels should be reviewed against the regulations applicable to each sales market.
Incoming-material acceptance should follow a written specification, appropriate analytical methods, and batch-specific documentation. A quality control program may include:
Test methods and acceptance limits should be appropriate for the product specification, manufacturing process, and destination market. Certification documents and third-party test reports should be reviewed for scope, validity, and relevance to the supplied material.
Zinc picolinate purity describes the measured proportion of the chemical compound, while elemental zinc content describes the amount of zinc present in that material. Because zinc picolinate contains only a fraction of zinc by weight, formulation calculations should use verified elemental content and the correct reporting basis.
Buyers should review compound identity, assay, elemental zinc content, heavy metals, moisture, microbiological quality, and relevant impurities. The COA should identify the batch, test methods, specifications, and actual results so incoming quality teams can assess each delivery against approved acceptance criteria.
Yes. Zinc Picolinate Powder is used in solid nutritional dosage forms, including capsules and tablets. Formulators should evaluate particle size, blend uniformity, excipient compatibility, and segregation risk to help maintain consistent ingredient distribution in each finished dosage unit.
Keep the powder sealed in suitable moisture-resistant packaging in a cool, dry place away from direct sunlight and excessive heat. A 24-month shelf life is a common industry reference, but the actual expiry period should be supported by product-specific stability data and approved batch documentation.
Common qualification documents include a current COA, product specification, TDS, SDS, relevant analytical method information, and applicable third-party test reports. Buyers should also verify batch traceability, storage conditions, packaging integrity, and any documentation required for the destination market.
Zinc Picolinate Powder is a defined nutritional ingredient for mineral supplements, premixes, and selected solid dosage forms. Effective procurement depends on verifying chemical identity, compound assay, elemental zinc content, impurity controls, and documentation suitable for the intended application. Clear specifications and consistent batch verification help support accurate formulation and reliable supply.
