What Is It?
Zinc Citrate is a mineral salt formed from the combination of zinc and citric acid — one of the most widely used and well-regarded zinc sources in nutraceutical and food supplement manufacturing. It is valued by formulators for its high elemental zinc loading, clean sensory profile, and excellent blending characteristics in dry powder applications.
Supplied as a white crystalline powder with no odour, this grade is engineered for straightforward integration into capsule, tablet, sachet, and premix formulations. Its high elemental zinc content of ≥31.3% on a dry basis means less ingredient is needed per dose compared to lower-loading zinc sources — supporting cost-effective formulation design and smaller finished capsule or tablet sizes.
Zinc is an essential trace mineral involved in immune function, skin health, hormone regulation, reproductive wellness, and hundreds of enzymatic processes in the body — making it one of the most consistently demanded micronutrients across virtually every supplement category.
Why This Ingredient Is In Demand
Zinc is one of the most widely included micronutrients in the Australian supplement market — appearing in immune health formulas, multivitamins, men’s and women’s wellness products, skin support blends, and sports nutrition. Zinc Citrate is a preferred source for manufacturers because of its high elemental zinc yield, low required inclusion rate, and clean label profile derived from simple raw materials — water, citric acid, and zinc oxide.
For formulators focused on potency, label transparency, and cost efficiency, Zinc Citrate is one of the most practical zinc sources available.
Features & Benefits
- High Elemental Zinc Loading – ≥31.3% elemental zinc on a dry basis — one of the highest zinc yields available, enabling precise dosing and efficient formulation design
- Odourless White Crystalline Powder – Clean sensory profile with no taste or odour interference in finished products
- Excellent Blending Characteristics – Fine crystalline structure integrates cleanly into capsule fills, tablet blends, sachets, and powder premixes
- Very Low Moisture – Loss on drying ≤1.0% supports excellent shelf stability and formulation consistency
- Tight Impurity Limits – Low chloride (≤0.05%), low sulfate (≤0.05%), and low iron (≤50 mg/kg) for clean specification control
- Compliant Heavy Metal Profile – Lead, arsenic, and cadmium all within strict international limits
- Simple, Transparent Raw Materials – Derived from water, citric acid, and zinc oxide — supports clean label and ingredient transparency commitments
- Cost-Effective Formulation – High zinc yield per gram reduces the volume of ingredient required per dose, lowering overall formulation cost
- Versatile Across Categories – Suited to immune health, skin support, men’s wellness, women’s health, multivitamin, and sports nutrition formulations
Why This Product Stands Out
≥31.3% Elemental Zinc – High-loading zinc source that maximises potency per gram of ingredient used Clean Sensory Profile – Odourless and white — no sensory interference in finished product applications Tight Quality Specifications – Low moisture, low impurities, and compliant heavy metals across all parameters Simple Ingredient Origin – Three raw materials only — water, citric acid, zinc oxide — for maximum label transparency Flexible Pack Sizes – Available in 1 kg, 5 kg, and 25 kg to suit R&D through to full-scale production
Elemental Zinc Dosage Guide
A practical reference for formulators calculating elemental zinc per dose:
| Zinc Citrate Quantity | Elemental Zinc Delivered (≥31.3%) |
|---|---|
| 100 mg | ≥31.3 mg elemental zinc |
| 150 mg | ≥46.9 mg elemental zinc |
| 200 mg | ≥62.6 mg elemental zinc |
| 300 mg | ≥93.9 mg elemental zinc |
| 500 mg | ≥156.5 mg elemental zinc |
| 1,000 mg (1g) | ≥313 mg elemental zinc |
Calculated on a dry basis at ≥31.3% Zn. Actual elemental zinc content may vary slightly by batch — refer to COA for confirmed assay values.
