Calcium ascorbate powder wholesale refers to the bulk purchase of a buffered, non-acidic form of vitamin C, typically supplied as a white, water-soluble powder in 25 kg drums or fiber drums. It is widely used in dietary supplements, food fortification, and beverage premixes because it is gentler on the stomach than plain ascorbic acid.
What is calcium ascorbate powder used for?
Calcium ascorbate combines ascorbic acid with calcium, delivering roughly 10% calcium by weight alongside vitamin C activity. Manufacturers choose it for tablets, capsules, powders, and ready-to-drink mixes where acidity or gastric irritation is a concern. It also functions as an antioxidant and nutrient fortifier in processed foods.
How do you choose a calcium manufacturer or supplier?
Start by verifying that the producer operates under GMP and can provide a current certificate of analysis for each lot. A reliable calcium supplier should also disclose heavy metal testing, particle size distribution, and shelf-life data. Many buyers source through established networks in China, where calcium salts production is concentrated and export documentation is well developed.
Which specifications matter most?
- Assay: typically 98% or higher on a dried basis.
- Appearance: free-flowing white powder with no caking.
- Solubility: clear solution in water for beverage use.
- Packaging: sealed drums with desiccant and liner.
How is wholesale pricing structured?
Prices depend on order volume, purity grade, packaging, and freight terms such as FOB or CIF. Smaller trial orders usually carry a higher unit cost than full-container loads. Buyers should confirm whether the quote includes testing, palletization, and documentation fees.
What should you check before placing an order?
Request a sample to confirm flowability and taste, and review the supplier's recall history and audit reports. For long-term supply, a written quality agreement helps prevent specification drift. Working with a transparent calcium manufacturer reduces the risk of rejected shipments and regulatory delays.
常见问题
Is calcium ascorbate powder the same as vitamin C?
It is a buffered form of vitamin C, meaning ascorbic acid is bound to calcium. This makes it less acidic and often easier on the stomach, but it still provides vitamin C activity. The calcium content is typically around 10% by weight.
What is the typical minimum order for wholesale?
Minimum order quantities vary by supplier, but many wholesale sellers start at 25 kg or one drum. Some offer smaller trial quantities at a higher unit price. Full-container or pallet orders usually get better pricing.
How should calcium ascorbate powder be stored?
Store it in a cool, dry place away from direct sunlight, keeping containers tightly sealed. Moisture and heat can cause caking or reduce stability. Always follow the supplier's recommended shelf life and handling instructions.
