Calcium gluconate monohydrate powder wholesale refers to the bulk purchase of the hydrated form of calcium gluconate, a white, water-soluble powder widely used in pharmaceuticals, food fortification, and animal nutrition. It is typically supplied in 25 kg bags or fiber drums, with purity grades ranging from food to USP/BP.
Why buy calcium gluconate monohydrate powder in bulk?
Bulk purchasing reduces per-unit cost and ensures a consistent supply for production lines. It also allows you to standardize on a single specification, which simplifies quality control and regulatory compliance.
How do you choose a reliable calcium supplier?
Start by verifying the supplier's manufacturing credentials, such as GMP, ISO, and FDA registrations. A reputable calcium manufacturer will provide a certificate of analysis (COA) for each batch and allow third-party testing. When sourcing from China, look for established exporters with a track record in calcium salts, as they often offer better pricing and reliable logistics.
What specifications matter most?
- Purity: Typically 98%–102% on a dried basis.
- Heavy metals: Must meet pharmacopeial limits (e.g., <10 ppm lead).
- Particle size: Fine powder for direct compression or granulation.
- Moisture content: Controlled to prevent caking.
Always request a sample before committing to a large order. This lets you test flowability, solubility, and compatibility with your formulation.
What are the common applications?
Calcium gluconate monohydrate is used in injectable solutions, oral supplements, and food products like beverages and dairy alternatives. In animal feed, it supports bone health and milk production. Its high solubility makes it ideal for liquid applications.
How to negotiate wholesale pricing?
Pricing depends on order volume, purity grade, and packaging. Ordering full container loads (FCL) usually lowers costs. Work with a calcium supplier who can offer flexible payment terms and stable lead times. For the best value, compare quotes from multiple suppliers and consider long-term contracts.
In summary, sourcing calcium gluconate monohydrate powder wholesale requires careful evaluation of suppliers, specifications, and logistics. Partnering with a trusted manufacturer ensures consistent quality and competitive pricing.

What is the typical shelf life of calcium gluconate monohydrate powder?
When stored in a cool, dry place in sealed containers, the powder typically has a shelf life of 2 to 3 years. Always check the manufacturer's COA for specific storage recommendations.
Can I get a sample before placing a wholesale order?
Yes, most reputable suppliers offer small samples for quality evaluation, though you may need to cover shipping costs. It's a standard step to ensure the product meets your specifications.
What are the main differences between calcium gluconate monohydrate and anhydrous forms?
The monohydrate form contains one water molecule per calcium gluconate unit, while the anhydrous form is water-free. Monohydrate is more common in pharmaceuticals due to its stability and solubility.
