1. How Do We Solve Your Quality Consistency & Bioavailability Problems?

Unpredictable raw materials lead to failed batches and compromised finished product efficacy. We place rigorous, validated analytics at the core of our production. We use High-Performance Liquid Chromatography (HPLC) as our primary method to guarantee ≥98% purity of Zinc Picolinate in every batch. Furthermore, we test for zinc content (20.0-21.0%), heavy metals (lead ≤0.001%), arsenic (≤0.0005%), and drying loss (≤2.0%). The compound has a molecular formula of C₁₂H₈N₂O₄Zn and a molecular weight of 309.6 g/mol. Each shipment includes a comprehensive Certificate of Analysis (CoA). Consequently, you can validate your raw materials quickly and launch products with total confidence in their absorption performance.

2. What Is It, and Why Is Our Manufacturing Superior?

Zinc Picolinate is a zinc salt of picolinic acid—a compound naturally produced in the body from the amino acid tryptophan that facilitates zinc absorption in the small intestine. It is available as an OTC dietary supplement used to treat and prevent zinc deficiency.

We produce our Zinc Picolinate through a validated synthesis process in a cGMP-compliant facility. The compound appears as a white to off-white crystalline or fine crystalline powder with slight hygroscopicity. It is slightly soluble in water, making it suitable for both solid dosage forms and specialized liquid applications. The compound has a melting point of 225-227°C (decomposing) and is stable when stored at room temperature.

3. Matching the Right Grade to Your Product Line

Your application is unique. We offer Zinc Picolinate in targeted grades:

• Nutraceutical Grade (99%): Ideal for capsules, tablets, and powder blends targeting immune support, skin health, wound healing, and testosterone metabolism. Clinical research supports its use for reducing the incidence of respiratory infections in children and reversing zinc deficiency in conditions like acrodermatitis enteropathica.

• Cosmetic Grade: Suitable for topical formulations for its soothing properties and skin repair benefits.

• Feed Grade: Designed for animal nutrition applications.

Tell us your application and target market. We will direct you to the most cost-effective and technically suitable grade.

4. Solving Your Formulation & Stability Problems

A common concern with minerals is their incompatibility with other formulation components. Our Zinc Picolinate addresses this with its stable white crystalline form and consistent properties. It is slightly soluble in water, making it suitable for both dry and specialized liquid formulations. It remains stable at room temperature and can be stored without special refrigeration. We recommend standard encapsulation processes for solid dosage forms, and for cosmetic applications, it can be incorporated into lotions and ointments.

5. Eliminate Inventory Waste with Proper Storage Guidelines

A hidden operational cost is ingredient degradation. Our Zinc Picolinate is stable when stored correctly. First, keep it in a cool, dry place away from direct sunlight and moisture. Next, store in tightly sealed, airtight containers to prevent moisture absorption due to its slight hygroscopicity. Under these conditions, the product maintains its full potency for 24 months from the date of manufacture. This extended shelf life allows you to purchase in cost-effective bulk quantities without fear of degradation.
