Zinc salts for dietary supplements wholesale are bulk-supplied inorganic or organic zinc compounds—such as zinc oxide, zinc sulfate, zinc gluconate, and zinc citrate—used by manufacturers to fortify capsules, tablets, and powders. Buying at wholesale volume lets supplement brands secure consistent quality and cost-effective pricing.
Which zinc salts are most common in supplements?
Zinc oxide offers high elemental zinc content and is cost-efficient, while zinc sulfate is highly bioavailable but can cause gastric irritation. Organic forms like zinc gluconate and zinc citrate are gentler and often preferred for premium products.
How do you verify quality when buying wholesale?
Request a certificate of analysis (COA) for each lot and confirm the zinc content, heavy-metal limits, and microbial safety. Reputable suppliers also provide third-party test reports and follow GMP or ISO standards.

China calcium salts and other mineral ingredients are widely exported, so buyers often evaluate Chinese suppliers for scale and price. Still, verify documentation and audit reports rather than relying on origin alone.
What should a wholesale agreement include?
- Specifications and COA per batch
- Lead times and minimum order quantities
- Packaging, storage, and shelf-life terms
Clear terms reduce risk and keep your zinc salts for dietary supplements wholesale supply stable.
常见问题
What is the difference between zinc oxide and zinc gluconate?
Zinc oxide is an inorganic salt with high elemental zinc content and low cost, while zinc gluconate is an organic form that is generally gentler on the stomach. The best choice depends on your formulation, target dosage, and label claims.
How do I confirm the purity of wholesale zinc salts?
Ask for a certificate of analysis for each batch and review the assay, heavy metals, and microbial limits. Independent third-party testing and supplier audits add further assurance.
Can I combine zinc and calcium ingredients from one supplier?
Yes, many mineral ingredient distributors carry both zinc and calcium salts. Consolidating orders can simplify logistics, but confirm that each ingredient meets its own specification and documentation requirements.
