Description
Magnesium Citrate Powder is a white, fine-powdered organic magnesium salt in which magnesium is chelated by citric acid for excellent solubility and absorption. The fine powder disperses quickly in liquids and blends evenly into dry mixes, making it the versatile choice for capsules, drink powders and fortified foods. Magnesium is an essential mineral for energy metabolism, nerve function, muscle relaxation and healthy bones, and the citrate form is recognized for its gentle, well-tolerated delivery. Produced from citric acid and magnesium oxide to USP and food-grade standards, with no carrier and no residual solvents, the powder offers a clean, single-ingredient mineral source with a two-year shelf life for supplement and food manufacturers worldwide. The fine particle size also makes it easy to disperse in liquids for drinkable magnesium products. It is packed in 25 kg bags and keeps for two years in a well-closed container in a cool place. The powder is a single-ingredient magnesium source with no carrier added. In practice the powder dissolves quickly in warm water, making it the preferred form for drinkable magnesium shots and effervescent tablets. It also fills capsules densely for standard-dose products. Batch records and test reports are available for every delivery, supporting buyer qualification, regulatory filing and long-term supply relationships. How the powder grade works: the fine particle size of this magnesium citrate gives it versatility across formats - it fills capsules densely, disperses quickly in drink mixes, and blends uniformly through food systems without gritty texture. The citrate chelation is the same well-absorbed, stomach-gentle magnesium chemistry, and because the product is a single ingredient with no carrier, labels stay clean and dosage math stays simple. Practical guidance: use it in magnesium capsules and tablets for sleep, muscle and energy support; dissolve it in warm water for drinkable magnesium shots; fortify dairy, cereals and nutrition bars at levels that deliver meaningful magnesium per serving; and combine it with B vitamins or botanicals in relaxation blends. Quality assurance: produced from citric acid and magnesium oxide to USP and food-grade standards, with no carrier and no residual solvents, and magnesium content, heavy metals and microbiology verified per batch with documentation supplied. Packed in 25 kg bags with a two-year shelf life in well-closed, cool storage. For manufacturers serving the everyday magnesium market, this powder is the practical, well-tolerated standard. Specification highlights: it is packed in 25kg/bag with a minimum order quantity of 1000kg. Certificates of analysis accompany every shipment, and sample supply, specification customization and flexible payment terms are available for qualified buyers, supported by the standardized seven-step service process from inquiry to after-sales support. Compliance and quality at a glance: the product is manufactured under the standards referenced in its specification sheet, and every batch is tested for identity, purity, heavy metals and microbiology before release. Batch records, test reports and certificates are kept and supplied for buyer qualification, audit and regulatory filing, and the product is stored and shipped in its original packaging to preserve quality through the supply chain. For industrial buyers, this documented quality system means one qualification covers years of consistent supply, with the specification sheet serving as the contractual reference for every delivery.
Applications
It is used in magnesium capsules and tablets, sleep and relaxation formulas, and electrolyte drink mixes. Powdered beverages and sports recovery products benefit from its fast dispersion. Food manufacturers fortify dairy, cereals and nutrition bars with magnesium, and personal care uses it in bath salts and skin formulations for relaxation.
Advantages
The fine powder form gives formulation freedom: it fills capsules densely, disperses quickly in drinks and blends uniformly in dry food systems without gritty texture. Its high solubility and citrate chelation deliver absorption that consumers can feel, supporting premium positioning. USP-grade purity, no carriers and a two-year shelf life keep labels clean and production simple.
