Bulk Magnesium Malate (≥99%) | Highly Bioavailable Organic Magnesium
Premium Pharmaceutical & Food Grade Magnesium Malate by Xi'an Tihealth
Formulating highly bioavailable magnesium supplements often forces R&D teams to choose between optimal absorption rates and gastrointestinal tolerance. Magnesium Malate bridges this gap perfectly.
Synthesized through an advanced gradient cooling crystallization process, Xi'an Tihealth Biotechnology Co., Ltd. produces a highly stable, organic compound of magnesium and malic acid. Boasting a rigorous purity of ≥99.2%, our Magnesium Malate fully complies with USP/EP pharmacopeia standards and international food safety regulations. It delivers exceptional water solubility, a stable particle morphology ideal for direct compression, and ultra-low heavy metal profiles. It is the trusted, high-performance mineral base for global nutraceutical brands targeting neuromuscular support, energy metabolism, and premium sports nutrition.
1. Formulation Advantages: Why Choose Our Magnesium Malate?
Sourcing organic minerals requires strict attention to physical properties and elemental yields. Here is how our ingredient builds competitive barriers for your manufacturing line
Superior Gastrointestinal Tolerance
Unlike inorganic salts (like Magnesium Oxide) which often cause osmotic diarrhea, the malic acid bond ensures sustained release and gentle cellular uptake, keeping adverse gastrointestinal reports below 5% in clinical formulations.
Synergistic Energy Profile
Malic acid is a vital intermediary in the Krebs (TCA) cycle. This dual-action compound not only replenishes essential magnesium but also provides the substrate needed for cellular ATP synthesis, making it unmatched for fatigue-focused formulas.
Optimized Particle Morphology
Engineered with a precisely controlled particle size (D50: 300-500 μm), our crystalline powder exhibits excellent flowability and low hygroscopicity, minimizing capping and sticking during high-speed tableting and encapsulation.

3. Primary Physiological Functions (R&D Perspective)
Replacing non-compliant medical claims with scientifically accurate functional descriptions, this ingredient supports formulations targeting:
By providing both elemental magnesium (an essential cofactor for ATP synthase) and malic acid (a key Krebs cycle intermediate), it comprehensively supports cellular energy production and helps mitigate exercise-induced physiological fatigue.
Magnesium plays a critical role in regulating calcium ion channels, preventing excessive muscle contractions. Its combination with malic acid aids in lactic acid clearance, making it an optimal base for post-workout muscle recovery protocols.
Essential for the activation of Vitamin D and the structural integrity of bone tissue. Furthermore, it supports endothelial function and maintains the sodium/potassium balance in myocardial cells, contributing to overall vascular health.
4. Targeted B2B Applications
Premium Dietary Supplements
The primary active ingredient in capsules, tablets, and stick-packs formulated for sustained energy, sleep support, and muscle relaxation.
Sports Nutrition & RTD Beverages
Its neutral flavor profile and excellent aqueous solubility make it highly suitable for isotonic hydration drinks and pre/post-workout powder blends.
Food & Beverage Fortification
Acts as a dual-purpose additive: a natural acidity regulator (due to malic acid) and a high-bioavailability mineral fortifier for functional dairy and baked goods.
FSMP (Foods for Special Medical Purposes)
Provides safe, highly tolerated enteral nutritional support for specialized metabolic requirements.

6. Formulation & Technical FAQ
How does Magnesium Malate perform in direct compression tableting?
Exceptionally well. Our crystallization process is optimized to yield a D50 particle size of 300-500 μm. This specific morphology provides high bulk density and excellent flowability, minimizing the need for extensive excipients or wet granulation processes during tableting.
What is the elemental magnesium yield in this compound?
Our Magnesium Malate provides a stable elemental magnesium content of approximately 11% to 15% (Typical batch: 12.3%). While this is lower than inorganic oxides, the significantly higher cellular absorption rate ensures greater physiological efficacy.
Is this raw material suitable for clear liquid formulations?
Magnesium Malate is classified as "sparingly soluble" in cold water (~1.0 g/L at 25°C). While excellent for opaque shakes, suspensions, and solid dosage forms, it may require specific pH adjustments or solubilizers for perfectly transparent liquid applications.
Are heavy metals rigorously controlled?
Yes. Operating under GMP and ISO9001 guidelines, we utilize ICP-MS testing to ensure heavy metals like Lead (< 1.5 ppm) and Arsenic (< 1.0 ppm) are strictly controlled, comfortably passing California Prop 65 and European Pharmacopoeia safety thresholds.
