Premium Zinc Picolinate Powder - Superior Bioavailability for Your Formulations
Since 2001, we have been dedicated to making high quality nutritional raw ingredients to solve genuine industrial problems. The market for mineral supplements is crowded, and what sets our Zinc Picolinate Powder apart is that it addresses a crucial problem you have – the bioavailability gap. Most forms of zinc have absorption rates of less than 20%, however our pharmaceutical grade Zinc Picolinate has better uptake efficiency, enabling your formulations to give therapeutic advantages at lower doses. This implies your end clients will have less GI side effects, better compliance and faster results. Our 20,000-square-meter ISO22000-certified factory, laboratory in accordance with SGS standards, and a staff of over 20 PhD-level researchers enable us to assure the quality of each batch of the product to satisfy the highest international standards.
Product Introduction
Our zinc picolinate bulk powder is a highly bioavailable organic zinc chelate, formed by the coordination of elemental zinc with picolinic acid, a natural metabolite of tryptophan. This white crystalline powder is of a pharmaceutical grade purity and 99% assay and provides a composition of about 20-21% elemental zinc. Unlike conventional zinc oxide or sulphate, our product is in molecularly intact form which survives the acid bath of the stomach and is optimally absorbed in the small intestine. The fine crystalline structure provides excellent flowability for encapsulation and tableting and the moderate water solubility is suitable for a variety of formulation applications in dietary supplements, functional foods and clinical nutrition products.
Third-Party Test Report
SGS Testing Partnership: Our product is routinely analyzed by SGS, the world's leading inspection and certification company. Independent tests confirm elemental zinc content, verify the absence of illegal pesticide residues and certify heavy metal levels far below EU and FDA guidelines.
Eurofins Verification: For clients targeting European markets, we provide Eurofins reports covering comprehensive microbiological screening, including Total Plate Count, Yeast & Mold, E. coli, and Salmonella. These reports ensure your formulations meet the strictest food safety regulations.

Zinc Picolinate Powder Advantages
Better Absorption Profile: Picolinic Acid Chelation Creates a Stable Molecular Complex Which is Better Absorbed in the Gastrointestinal Tract Than Inorganic Zinc Salts. Your formulations require less elemental zinc to reach equivalent serum levels hence decreasing the likelihood of copper displacement and gastrointestinal discomfort experienced with conventional zinc solutions.
Formulation Flexibility: Our powder is compatible with a variety of delivery modalities. The small particle size distribution and controlled moisture content ensure that caking does not occur during storage, and the heat stability up to 200°C permits smooth incorporation into tableting, encapsulation and even soft-gel technologies without concerns of deterioration.
Zinc Picolinate Powder Application
Premium Immune Support Supplements: Our Zinc Picolinate Powder is the formulator's choice for high-potency immune defence solutions. Where quick zinc uptake is needed. The better absorption permits effective single 30-50mg dosages in one capsule, boosting T-cell activity and cytokine balance throughout seasonal challenges, without the nausea associated with zinc sulphate.
Advanced Dermatological Nutricosmetics: Beauty-from-within formulations targeting acne, wound healing, and skin barrier function rely on zinc's anti-inflammatory and sebum-regulating properties. Our picolinate form is more bioavailable to skin tissues, making it the form of choice for premium skin clarity blends with vitamins A, C and E.

Production Process
Step 1 - Raw Material Selection & Purification: We purchase pharmaceutical grade zinc salts and picolinic acid from approved vendors and check each batch of incoming material for heavy metals using ICP-MS and purity using HPLC.
Step 2 - Controlled Chelation Reaction: In our GMP-certified synthesis facility, zinc and picolinic acid are reacted under carefully controlled chelation conditions under optimised pH and temperature parameters monitored by automated systems.
Step 3 - Crystallisation and Purification: The reaction solution is cooled and crystallised under controlled conditions and vacuum filtered and washed many times with purified water systems.
Step 4 - Precision Drying & Milling: Washed crystals are moved to our 100,000-class purification workshop where vacuum drying at controlled temperatures is used to eliminate moisture to less than 2%, followed by specialised milling equipment to get the particle size to exacting 80-mesh requirements.
Step 5 - Quality Verification and Packaging: Each production batch is fully tested in accordance with our ISO22000 protocols – HPLC assay, elemental zinc determination, microbiological testing and heavy metal analysis – prior to packaging into pharmaceutical grade PE bags within fibre drums with nitrogen flush.

FAQ
Q: Does zinc picolinate absorb better than other zinc forms?
A: Clinical studies show zinc picolinate has higher bioavailability than zinc gluconate, citrate, and oxide. Picolinic acid chelate protects zinc via the stomach and improves intestinal mucosa active transport, improving absorption by 20-40% depending on the comparative form.
Q: The typical dosage range for dietary supplements is?
A: An immune support and general wellness product typically contains 15-30mg elemental zinc per serving. Therapeutic uses for skin health or deficit correction may be 30-50mg. Our product contains 20% elemental zinc, thus formulators utilise 75-150mg per capsule or tablet.
Q: Does your zinc picolinate work in vegan and vegetarian products?
A: Yes. Our product is vegan, vegetarian, and VEGAN-certified, as it is 100% plant-derived and free of animal products. Clean label positioning is supported by complete allergen statements and non-GMO evidence.
