Every batch of zinc sulphate 7H₂O is equipped with complete food safety test reports and batch certificates. All indicators are tested by third-party authoritative institutions, supporting food product filing, market supervision inspection and global cross-border sales for supplement manufacturers.
Diverse Application Scenarios in Dietary Supplement Industry
As a classic and mature mineral fortifier, zinc sulphate heptahydrate has been widely adopted in the global dietary supplement industry due to its high cost performance and stable compatibility. It is suitable for almost all mainstream nutritional supplement formulas, and will not conflict with vitamins, minerals, amino acids and other common formula ingredients, with wide application adaptability:
Solid Zinc Supplement Products
It is the preferred raw material for ordinary zinc tablets, compound mineral tablets, multivitamin mineral chewable tablets and sports nutrition solid powders. Its fine powder form can be evenly mixed with other solid ingredients, ensuring uniform zinc content in each finished tablet. It will not cause color change or ingredient failure during tableting and drying processes, effectively improving the qualification rate of finished supplement products.
Liquid Nutritional Supplements
With excellent water solubility and solution stability, the product is widely used in oral zinc liquid, children's nutritional syrup, functional drinking water and liquid compound supplements. After dissolution, it maintains clear texture and stable nutritional activity, no stratification or precipitation after long-term placement, which perfectly meets the quality requirements of liquid health products.
Special Crowd Nutritional Formulas
It can be used in maternal nutritional supplements, adolescent growth nutrition powders, elderly mineral fortification products and sub-health conditioning supplements. As an essential trace element, zinc can effectively assist human immune regulation, promote growth and development, and improve skin and mucosal health, matching the daily nutritional supplement needs of all age groups.
Functional Food Fortification
In addition to single supplements, our zinc sulphate 7H₂O is also applicable to fortified cereal powders, nutritionally enhanced snack powders and meal replacement formulas. It provides stable zinc element fortification for daily functional foods, helping manufacturers enrich product nutrition attributes and enhance market competitiveness.
Product Advantages for Dietary Supplement Manufacturers
1. Professional Food-Grade Safety Guarantee
This product is specially developed for food and supplement industries, with production workshops meeting food-grade sanitation standards. Different from pharma-grade products with excessive purification and industrial-grade products with unqualified impurities, it accurately meets food safety standards, avoiding compliance risks caused by excessive or unqualified indicators, and is more suitable for long-term mass production of dietary supplements.
2. Excellent Formula Compatibility
The optimized crystal structure reduces chemical activity, ensuring stable coexistence with VC, VB group, calcium, iron and other common supplement ingredients. It will not cause oxidative failure or nutritional loss of matching ingredients, greatly improving the shelf life stability of finished dietary supplements.
3. High Cost-Performance Mass Supply
Compared with organic zinc sources such as zinc gluconate and zinc glycinate, zinc sulphate 7H₂O has higher zinc content and lower production cost, which can effectively reduce the raw material cost of supplement manufacturers while ensuring nutritional efficacy. We support long-term bulk supply with stable pricing, helping customers control production costs and expand market profit margins.
4. Customized Processing Support
We can adjust particle fineness and moisture index according to customers' formula and production equipment needs. Whether for high-precision tablet pressing production or low-precision powder mixing processing, we can provide matched customized products, and support small-batch trial orders and large-batch container orders.
We adopt food-level sealed packaging for all products, with inner food-grade PE sterile bags and outer thickened moisture-proof woven bags, effectively preventing moisture absorption and pollution during transportation. Special food-grade vacuum packaging is available for high-end supplement production needs to ensure zero secondary pollution.
The product should be stored in a dry, cool and ventilated food raw material warehouse, away from moisture, high temperature, toxic and harmful substances. Sealed storage is required after opening to prevent crystal weathering and agglomeration. Under standard storage conditions, the product maintains stable performance within the shelf life, without affecting the efficacy of finished supplement products.
