Calcium glycinate brings together calcium and glycine to form a chelated compound recognized for its role in dietary supplements, food fortification, and a variety of chemical applications. This substance appears as a white to off-white solid, easily handled in powder, flakes, or crystalline forms. At room temperature, its appearance signals purity and stability. In terms of structure, calcium sits bonded within the glycinate framework, supplying a reliable, bioavailable calcium source in nutritional products, veterinary formulas, and specialty chemicals.
Across industries, calcium glycinate shows up in products that support bone health, address mineral deficiencies, and stabilize food ingredients. In supplements, its high absorption rate makes it preferable over traditional calcium salts, easing gastrointestinal discomfort for many individuals. Food technologists appreciate its neutral taste and predictable solubility. In pharmaceuticals and nutraceuticals, the compound’s purity and defined composition contribute to batch consistency. Raw materials selection often influences final product quality, making calcium glycinate a sought-after option where purity and traceability take top priority.
Calcium glycinate holds a molecular formula of C4H8CaN2O4 and a molecular weight around 188.19 g/mol. Density typically falls near 2.0 g/cm³. This compound sits comfortably at standard atmospheric conditions, neither volatile nor prone to sudden degradation. Solubility trends dictate usage—moderately soluble in water, giving clear to slightly cloudy solutions. Available as powder, flakes, or crystals, it fits diverse material demands. Quality checks ensure defined calcium content, absence of heavy metals, and controlled moisture, all documented on product specifications. Some suppliers also produce liquid forms, though they often tailor those for rapid blending or precision dosing.
The chelated structure pairs the calcium ion with the amino acid glycine. Chemical stability remains one of its core strengths. Standards require each batch to exceed purity thresholds, and modern labs run spectral analyses to confirm identity. Touch, inhale, or accidental ingestion does not pose significant acute toxicity if handled as directed; this stands in contrast to many industrial chemicals that demand stricter protocols. Chronic exposure studies indicate low risk when used as intended. Nevertheless, all chemical handlers rely on gloves and protective eyewear, following general lab safety. Safety documentation (SDS sheets) clarifies hazard classifications—not typically listed as hazardous or harmful under normal concentrations. Calcium glycinate’s use in food and veterinary products underscores its favorable safety record.
For customs and trade, calcium glycinate typically uses HS Code 292249. This ties into glycine derivatives and salt entries, aiding importers and exporters with accurate shipping and regulatory filings. Manufacturers provide purity, lot number, and country of origin documentation. In the global market, traceability grows more important every year. Certificates accompany shipments, confirming raw materials sourcing, and complying with local and international standards like USP, FCC, or E Number regulations.
Calcium glycinate comes in several forms. The powder is fine-textured and dusts easily, favored where rapid dissolution is needed. Flakes flow well and measure consistently in process lines. Pearls are less frequent, chosen for specialized applications needing slower release. Liquid and solution formats appeal to manufacturers seeking simplified dispersion or direct addition to wet formulations. Each form meets particular requirements—choices depend on storage, processing equipment, and final product goals. In the lab and production environment, form influences weighing accuracy and quality control measures. Specific density and packing details guide how much raw material enters each load.
The chelation of calcium by glycine, an amino acid, stands out here. Chelation shields the calcium from binding with dietary inhibitors, helping the body absorb more with fewer side effects. The molecular structure resists rapid precipitation in aqueous solutions, giving formulators extra certainty in shelf life predictions and product performance. In animal nutrition, feed specialists lean on this form’s gentler absorption profile to boost calcium without risking digestive upset in sensitive species. The inclusion of an amino acid enhances biological compatibility.
Most users find calcium glycinate safe under common handling conditions. Typical safety sheets flag dust inhalation and contact hazards as minor, recommending basic PPE without calling for emergency controls. Large-scale users focus on keeping workplace dust levels low, storing sealed containers away from moisture, and preventing cross-contamination. Disposal protocols do not require hazardous waste procedures unless mixed with other dangerous chemicals. This chemical’s low-hazard rating does not mean casual handling—safe habits prevent accidents and maintain both product quality and worker health.
Trust in calcium glycinate starts with raw materials. Producers trace their calcium and glycine sources, sometimes as far back as the mineral ore or fermentation batch. Consistent, audited suppliers keep impurities below regulated thresholds. Paperwork, certificates, and occasional third-party audits all support a dependable supply chain. Buyers expect and receive regular testing documentation. As demand grows in both food and pharmaceutical markets, the focus on sustainable, ethical sourcing grows. Documenting origin and quality protects brand integrity and consumer trust, especially where ingredients travel between countries with different regulations.
