Magnesium citrate Anhydrous

(Powder, Tablets and Capsules)

The Gold Standard in Magnesium Bioavailability: Premium Anhydrous Magnesium Citrate by SRBio

SRBio Anhydrous Magnesium Citrate is the industry benchmark for mineral supplementation. Produced from the reaction of high-purity citric acid and magnesium carbonate, this white, odorless powder offers superior solubility and exceptional bioavailability. As the anhydrous form, it provides a higher concentration of elemental magnesium compared to its hydrated counterparts, making it the ideal choice for formulators seeking maximum efficacy in compact dosage forms like tablets and capsules.

Uncompromising Quality: SRBio’s Manufacturing Excellence

1. Precision Purity & Composition Control

   • Guaranteed Elemental Magnesium: Our production process is tightly controlled to ensure a consistent elemental magnesium content between 14.5% and 16.4%, allowing for precise and reliable formulation.

   • High Purity Assurance: Product purity exceeds 98% as anhydrous magnesium citrate, verified by HPLC for citrate content.

   • Heavy Metal Screening: ICP-MS validated limits: Arsenic (<0.5 ppm), Lead (<0.1 ppm), Cadmium (<0.05 ppm), Mercury (ND). Compliant with global pharmacopoeia (USP/EP/FCC).

   • Residual Solvents: GC-FID tested; confirms absence of organic solvents, as our process is entirely water-based.

2. Advanced Synthesis Technology

   • Controlled Reaction & Crystallization: Our proprietary process reacts high-purity magnesium carbonate with food-grade citric acid under precisely controlled conditions. This ensures complete reaction and the formation of a consistent, high-purity anhydrous salt.

   • Multi-Stage Purification: The product undergoes rigorous washing and recrystallization to eliminate any residual reactants or by-products, guaranteeing exceptional purity and a neutral taste profile.

   • Low-Impact Drying: Utilizes low-temperature vacuum drying technology to remove free moisture without degrading the product or causing premature hydration. This preserves the integrity of the anhydrous form.

   • Eco-Impact: Water-based synthesis with minimal waste, aligning with sustainable manufacturing principles.

3. Stability & Shelf-Life Superiority

   • Accelerated Stability Data: Retains ≥99% potency and shows no discoloration after 24 months at 25°C/60% RH (ICH Q1A tested) when packaged appropriately.

   • Hygroscopicity Management: While magnesium citrate is known to be hygroscopic, our advanced processing and packaging minimize moisture pickup. Storage in original, tightly sealed containers is recommended.

   • Light/Oxygen Protection: Nitrogen-flushed, moisture-barrier foil packaging with desiccant guarantees stability from factory to formulation.

Scientific Evidence: Mechanism & Efficacy

1. Superior Bioavailability & Absorption

   • High Solubility: With solubility exceeding 180 g/L in water, it dissolves rapidly in the gastrointestinal tract, making the magnesium readily available for absorption.

   • Enhanced Uptake: Clinical studies have consistently shown that organic magnesium salts like citrate offer superior bioavailability compared to inorganic forms (e.g., oxide), as they are less dependent on stomach acid for dissolution. *[Reference: Magnes Res. 2018; 31(4): 131-139]*

2. Essential Physiological Roles

   • Energy Metabolism: Magnesium is a critical cofactor for over 300 enzymatic reactions, including those involved in ATP (energy) production and glucose metabolism.

   • Muscle & Nerve Function: It plays a vital role in regulating muscle contractions, nerve transmission, and neuromuscular excitability, helping to reduce cramps and support relaxation.

   • Bone Health: Approximately 60% of the body’s magnesium is stored in bone, where it contributes to structural integrity and regulates calcium transport.

3. Recognized & Recommended

   • EFSA-Approved Health Claims: Recognized by the European Food Safety Authority for contributions to normal energy-yielding metabolism, muscle function, and maintenance of bones and teeth.

   • Global Acceptance: Widely used in infant formula, clinical nutrition products, and weight management protocols across Europe, the Americas, and Asia.

Formulation-Ready Advantages

Application-Specific Benefits:

• Tablets & Capsules: High bulk density and excellent compressibility allow for smaller tablet sizes with higher magnesium content per dose. Provides smooth, non-gritty disintegration.

• Powdered Beverages & Stick Packs: High solubility ensures rapid and complete dissolution, resulting in clear or slightly hazy solutions with a neutral taste.

• Functional Foods & Nutrition Bars: Stable and non-reactive; does not catalyze rancidity in fats. The neutral flavor profile does not interfere with the finished product’s taste.

• Liquid Formulations: Ideal for syrups, drops, and oral solutions due to its high solubility and stability in aqueous media.

Supply Chain & Compliance Leadership

1. Audited Transparency

   • Full Traceability: Batch-specific Certificates of Analysis (COA) with complete heavy metal and microbial profiles are always available.

   • Production Capacity: Multiple production lines across ISO 9001 and GMP-certified facilities ensure consistent supply and scalability from R&D batches to full-scale commercial production.

2. Regulatory Preparedness

   • Global Compliance: Meets Food Chemicals Codex (FCC), USP/NF, and EP standards. Full documentation for GRAS determination, EU Novel Food compliance, and other regional filings available.

   • Allergen Statement: Validated free from gluten, soy, dairy, nuts, and crustaceans (ELISA tested). Produced in dedicated allergen-managed facilities.

3. Ethical Certifications

   • Kosher & Halal Certified: Available upon request.

   • Vegan & Non-GMO Verified: Sourcing and production processes ensure a final product suitable for all dietary preferences and lifestyles.

   • Ecovadis Recognition: Committed to ethical labor practices and sustainable manufacturing.

Competitive Breakdown: SRBio vs. Market Alternatives

Key Deficiencies in Standard Magnesium Citrate:

• Hydration Inconsistency: Variable water content (e.g., nonahydrate) leads to inconsistent magnesium potency and challenges in precise formulation.

• Poor Flow & Clumping: High hygroscopicity, if not managed properly, results in poor powder flow, sticking in tablet presses, and caking in bulk containers.

• Unpleasant Taste: Incomplete purification leaves a bitter or metallic aftertaste, making palatable formulations difficult.

• Low Density: Fluffy powders with low bulk density require excessively large capsule sizes, which are difficult for consumers to swallow.

SRBio’s Manufacturing Edge:

• True Anhydrous Form: Guaranteed anhydrous composition ensures maximum and consistent magnesium content, allowing for smaller, consumer-friendly dosage forms.

• Optimized Organoleptics: Rigorous washing and purification remove bitter by-products, resulting in a neutral-tasting powder ideal for high-quality supplements and foods.

• Superior Flow & Handling: Engineered particle morphology and density minimize clumping and ensure smooth, high-speed processing.
