Magnesium Lactate
Magnesium Lactate (C₆H₁₀MgO₆ · 2H₂O) is an organic mineral salt produced via the controlled reaction and crystallization of high-purity food-grade lactic acid with magnesium sources. It functions primarily as a highly bioavailable mineral supplement and pH-buffering agent in functional foods, dietary supplements, and pharmaceutical formulations.
Manufacturing operations are conducted in dedicated synthesis facilities using 316L stainless steel reaction systems under FSSC 22000 and cGMP frameworks. Each production lot is quantitatively analyzed via complexometric titration and ICP-MS elemental screening to verify compliance with USP, FCC, and EP monographs.

FAQ
Q: What differentiates Magnesium Lactate from Magnesium Oxide or Citrate?
A: Magnesium lactate contains approximately 10% elemental magnesium by weight and provides significantly higher aqueous solubility and gastrointestinal tolerance than oxide or citrate alternatives, minimizing laxative side effects in sensitive formulations.
Q: Does this product comply with USP and FCC monographs?
A: Yes. Synthesis, analytical testing, and final product release comply fully with current United States Pharmacopeia (USP) and Food Chemicals Codex (FCC) standards.
Q: What is the minimum order quantity (MOQ) for bulk shipments?
A: The standard MOQ is 500 kg (20 x 25 kg drums) to fit standard ocean freight pallet configurations. 1 kg sample quantities are available for R&D laboratory evaluation.
Q: Can the particle size distribution be customized for specific tableting machines?
A: Yes. Air-classifier milling systems allow us to adjust mesh size distributions to meet specific bulk density and flowability requirements for high-speed direct compression.
Q: What analytical methods are used for heavy metal verification?
A: Every production lot is analyzed using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to measure trace levels of lead, arsenic, cadmium, and mercury against strict threshold limits.
Q: How is batch-to-batch consistency maintained during production?
A: Consistency is controlled through automated reactor feeding, calibrated online crystallization monitoring, and a mandatory 3-year retention sample archive for every manufactured lot.
