Magnesium Glycinate 12% Powder

Product Overview

This Magnesium Glycinate 12% is a high-purity, fully reacted, non-buffered magnesium chelate. It is formed by binding one magnesium atom to two molecules of the amino acid glycine (Magnesium Bisglycinate). This chelated structure (CAS 14783-68-7) is highly valued in dietary supplements and functional foods as it utilizes the amino acid transport pathway for absorption, offering superior bioavailability and gastrointestinal tolerance compared to inorganic salts like magnesium oxide.

Our 12% elemental magnesium grade is a fine, white crystalline powder, optimized for consistency and purity. Its characteristic alkaline pH (typically 9-12) serves as a key indicator of its non-buffered, fully reacted state, distinguishing it from lower-purity or “buffered” products that are blended with magnesium oxide.

Key Advantages for Formulation & Sourcing:

• High Bioavailability: Chelated structure designed for enhanced absorption.
• Excellent GI Tolerance: Minimizes the laxative effect often associated with other magnesium forms.
• Guaranteed Purity: ≥ 12% elemental Mg. Non-buffered and fully reacted.
• Technical Transparency: We provide clear data on its alkaline pH and offer formulation guidance for its use.
• Consistent Supply: Available in bulk quantities direct from the manufacturer, ensuring reliable supply chain and batch-to-batch consistency.

Applications & Formulation Guidance

Magnesium Glycinate 12% is an ideal choice for fortifying supplements and functional foods with a highly bioavailable, stomach-friendly source of magnesium.

Solid Dosage (Capsules & Tablets)

The powder’s physical properties (bulk density and particle size) are optimized for use in:

• Two-piece hard capsules: Provides excellent flowability for high-speed encapsulation.
• Tablets (Wet Granulation): Serves as the primary active. (For direct compression, please inquire about our DC grade).
• Powder Blends & Sachets: Blends easily with other non-acidic ingredients.

Formulation Guidance: Beverages & pH-Sensitive Blends

A critical formulating consideration for non-buffered Magnesium Glycinate is its characteristic alkaline pH (9.0-12.0).

• The Challenge: When added to water, this product will significantly increase the solution’s pH. This can be incompatible with acidic formulations (like citrus-flavored beverages) or ingredients that are sensitive to high pH (e.g., certain vitamins, flavors, or preservatives like sodium benzoate).
• The Indication: This alkaline profile is the chemical proof that the product is a high-purity, fully reacted bisglycinate, not a buffered blend containing magnesium oxide.
• The Solution: For acidic or pH-neutral liquid and powder systems, a food-grade acidulant (such as citric acid, malic acid, or tartaric acid) must be used as a buffering agent to adjust the final pH to the desired range (e.g., pH 3.5-4.5 for a beverage).

Our technical team is available to discuss your specific application and provide starting-point recommendations for pH adjustment.

Stability, Storage, and Packaging

• Stability: This product is chemically stable. However, it is hygroscopic (will absorb moisture from the air).
• Storage: Store in a cool, dry place in its original, tightly sealed container. Avoid exposure to high humidity and direct sunlight.
• Packaging: Standard packaging is a 25kg net weight fiber drum with an inner food-grade PE liner.
• Supply: As a global supplier and factory source, we offer bulk pallet quantities and can discuss custom packaging requirements.

Frequently Asked Questions (FAQ)

Q: What is the pH of Magnesium Glycinate 12% in water?

A: The pH of a 1% (10g/L) solution is highly alkaline, typically between 9.0 and 12.0. Our COA shows a typical result of 10.2. This is a normal and expected characteristic of high-purity, non-buffered magnesium bisglycinate.

Q: What is the difference between this “non-buffered” product and “buffered” magnesium glycinate?

A: “Non-buffered” (like this product) is pure, fully reacted magnesium glycinate, delivering ≥ 12% elemental Mg. “Buffered” products are blends of magnesium glycinate with magnesium oxide. While buffering may increase the total magnesium percentage, it dilutes the benefits of the glycinate chelate and re-introduces the poor solubility and GI tolerance issues of magnesium oxide.

Q: Is the 12% content the “elemental” magnesium?

A: Yes. The ≥ 12% specification refers to the elemental magnesium (Mg) content, which is the critical value you use to calculate your product’s “Supplement Facts” panel or label claim.

Q: How do I manage the high pH in my beverage formulation?

A: You must use a food-grade buffering system, typically by adding an acidulant like citric acid. The amount of acid needed depends on your target pH and other ingredients. Please contact our technical team for a formulation consultation.

Q: Are you the direct manufacturer?

A: Yes, we are the original manufacturer and bulk exporter of this material. We provide full traceability and supply directly from our factory, ensuring quality control and stable pricing.

Q: What is the HS Code for Magnesium Glycinate?

A: The typical HS Code is 2922 49 (or a related subheading, e.g., 2922 49 85). Please confirm with your customs broker for your specific region.
