Magnesium Malate
Magnesium Malate (C₄H₄MgO₅, CAS No.: 3094-17-9 / 142-71-2, supplied primarily as dihydrate) is an organic chelated mineral salt synthesized by reacting elemental magnesium with high-purity malic acid. It is widely specified in solid and liquid nutritional formulations for its high oral bioavailability and superior gastrointestinal tolerance relative to inorganic mineral salts.
Manufactured in our cGMP and ISO 22000-certified facility, our Magnesium Malate powders are engineered for reliable downstream processing, including capsule filling, direct compression (DC), and wet granulation. Our production methodology ensures batch-to-batch consistency, tightly controlled microbial bio-burden, and full raw material traceability.

Applications
Dietary Supplements: Formulated into capsules, tablets, and dry-blended drink powders. Because malic acid is a critical intermediate in the cellular Krebs cycle (ATP synthesis), this raw material is preferred for formulations targeting cellular energy production and muscle recovery.
Functional Foods & Beverages: Utilized in sports nutrition mixes due to its clean taste profile and stable aqueous dispersion characteristics.
Pharmaceutical Preparations: Applied as an organic magnesium source in specialized delivery systems requiring strict impurity control.
Product Grades & Options
To align with specific manufacturing equipment and processing techniques, we offer three core particle profile configurations:
Standard Powder (Mesh 80): Optimized for conventional capsule filling and standard wet granulation lines.
Fine Powder (Mesh 100 - 200): Micronized distribution designed for accelerated dissolution kinetics and uniform dry blending.
Direct Compression (DC) Grade: Granulated texture engineered with high flowability and binding capacity to prevent capping and weight variation on high-speed rotary tableting presses.
Quality Control & Documentation
Analytical Verification: Every outgoing lot undergoes multi-parameter testing via ICP-MS (heavy metals), HPLC (assay validation), laser diffraction (particle size), and automatic titration.
Third-Party Validation: Periodic batch testing is executed by accredited external laboratories (SGS and Eurofins) to ensure continuous compliance with global pharmacopeia standards.
Regulatory Documentation Supplied:
1.Certificate of Analysis (CoA) per individual lot
2.Material Safety Data Sheet (MSDS / SDS)
3.BSE/TSE-Free Statement
4.Non-GMO Statement
5.Allergen Statement
6.Residual Solvents Compliance Declaration (ICH Q3C)
Packaging & Storage
Standard Packaging: 25 kg net weight fiber drums lined with food-grade dual polyethylene bags. Sample and pilot-scale quantities (1 kg - 5 kg) are supplied in hermetically sealed aluminum foil bags.
Storage Environment: Store in a cool, dry, well-ventilated space away from direct light and atmospheric moisture. Keep containers tightly closed.
Shelf Life: 24 months from the manufacturing date in unopened original packaging.
FAQ
Q: What distinguishes Magnesium Malate from Magnesium Citrate?
A: Magnesium Malate pairs magnesium with malic acid, supporting cellular energy (Krebs cycle) pathways with minimal gastrointestinal upset. Magnesium Citrate utilizes citric acid and exhibits a higher osmotic laxative effect at elevated doses.
Q: Is your commercial product dihydrate or anhydrous?
A: Our primary standard stock is Magnesium Malate Dihydrate. Anhydrous configurations can be scheduled for production upon request for specialized moisture-sensitive applications.
Q: Are there any flowing agents or excipients blended into the powder?
A: No. The product consists of 100% pure Magnesium Malate, completely free from anti-caking agents, flow aids, or preservatives.
Q: What is the Minimum Order Quantity (MOQ) for bulk shipments?
A: Standard bulk production MOQ is 500 kg (packed in 25 kg drums). Trial or lab-scale samples (up to 1 kg) are available for initial R&D evaluation.
Q: Does your facility hold religious dietary certifications?
A: Yes, our production facility maintains current Kosher and Halal certifications, available upon request during supplier auditing.
Q: What is the standard production and shipping lead time?
A: For active standard grades, lead time spans 14 to 21 days from order confirmation to port loading.
