Product Overview
Magnesium Glycinate Powder, also known as Magnesium Bisglycinate, is a chelated magnesium ingredient widely used in nutraceutical and dietary supplement formulations.
For commercial sourcing, buyers should confirm the assay basis, elemental magnesium content, particle characteristics, and whether the material is fully reacted or blended/buffered according to the intended formulation and finished dosage form.
Lifeworth supplies 99% Magnesium Glycinate Powder for capsule, tablet, powder blend, and OEM supplement projects, with batch COA, TDS/specification, SDS/MSDS, sample support, and bulk packaging options available according to project requirements.

Applications
Dietary Supplements
Chelated magnesium ingredient for capsule, tablet, stick pack, and powder blend formulations where elemental magnesium content, particle characteristics, and dosage requirements are considered during product development.
Powder Blends & Stick Packs
Suitable for selected powder blend, sachet, and stick pack formulations. Flowability, taste profile, moisture behavior, and compatibility with other ingredients should be evaluated in the finished formulation.
Sports & Wellness Formulations
Magnesium Glycinate Powder may be used in selected sports nutrition, daily wellness, and mineral supplement formulations where a chelated magnesium ingredient is preferred.
Supply for OEM & Contract Manufacturers
Bulk Magnesium Glycinate Powder is available for supplement brands, OEM and contract manufacturers, and ingredient distributors requiring defined specifications, batch documentation, sample evaluation, and commercial ingredient supply.
Buyers evaluating different magnesium forms for supplement formulations may also review our Magnesium L-Threonate Powder for projects requiring a different magnesium ingredient profile and formulation positioning.
How to Choose the Right Grade / Form
How to Choose the Right Magnesium Glycinate Specification
1. Confirm the Assay Basis
Review how Magnesium Glycinate or Magnesium Bisglycinate content is defined and reported in the specification. The assay basis and test method should be clear before comparing materials from different suppliers.
2. Review the Elemental Magnesium Target
Elemental magnesium should be evaluated separately from total Magnesium Glycinate assay. If your formulation requires a specific Mg% target, this can be discussed according to dosage form and project requirements.
3. Confirm Whether the Material Is Buffered or Non-Buffered
Some commercial Magnesium Glycinate materials may be blended or buffered with other magnesium sources. If the project requires fully reacted or non-buffered material, this should be confirmed before quotation and sample evaluation.
4. Match Particle Characteristics to the Dosage Form
Capsules, tablets, powder blends, and stick packs may require different particle size, flowability, and handling characteristics. The intended dosage form should be confirmed before final material selection.
5. Confirm Quality and Documentation Requirements
Before commercial sourcing, buyers should confirm required quality parameters, batch documentation, packaging, and destination-market requirements so that the supplied specification matches the intended project.
Technical & Formulation Notes
Technical Notes
Magnesium glycinate/bisglycinate should be sourced with a clearly defined assay basis and test method. If “99%” is used in labeling or technical review, buyers should confirm how the assay is defined in the TDS/spec sheet and ensure that it aligns with their destination-market and formulation requirements.
Manufacturing & Process
Typical manufacturing involves controlled chelation of magnesium with glycine, followed by purification, drying, and in-process QC. Final release is based on agreed specification items such as assay basis, elemental magnesium content, moisture/LOD, particle size, and market-specific limits.
Compatibility / Formulation Notes
- Confirm elemental magnesium content before dosage calculation or label claim design.
- For capsule and tablet production, review particle size, flowability, and bulk density before scale-up.
- For powder blends, pilot testing is recommended to check dispersibility, taste impact, and compatibility with other minerals or actives.
- Keep the material sealed and dry during storage and handling to reduce moisture-related caking risk.
- If “fully reacted” or “non-buffered” positioning is required, confirm this point in the specification and supplier documentation.

Product specifications
| Test | Specification | Method |
|---|---|---|
| Assay (as Magnesium Bisglycinate Chelate) | >=99% (per specification) | Per spec (USP/FCC reference) |
| Elemental Magnesium (Mg) | Typical 13%-C14% (custom targets on request) | ICP-OES (typical) |
| Molecular formula / MW | C4H8MgN2O4; 172.42 g/mol (anhydrous) | Reference / label |
| Appearance | White to off-white powder | Visual |
| Solubility | Solubility depends on spec & test conditions; confirm in TDS | Per spec |
| Loss on drying (LOD) | Meets agreed limits (per specification) | USP (typical) |
| Heavy metals | Meets destination-market limits (as required) | ICP-MS / USP (typical) |
| Microbiology (food/supplement grade) | Meets agreed limits (as required) | USP / ISO (typical) |
Storage, Shelf Life & Packaging
Storage
Store in a cool, dry, and well-ventilated area. Keep tightly sealed in the original container with inner liner intact. Protect from moisture, direct sunlight, and strong odors. Avoid repeated opening in high-humidity environments; reseal immediately after each use. Use clean, dry tools during handling and prevent cross-contamination.
Moisture control is recommended during transit and warehouse operations (e.g., inner liner integrity, desiccant when applicable). Keep away from heat sources and prevent exposure to water during loading/unloading.
Shelf Life
24 months from the manufacturing date when stored in the original, unopened packaging under recommended conditions. After opening, shelf life may be reduced; for best stability, keep containers sealed between uses and use promptly after opening. Refer to the COA/batch label for the exact retest/expiry information.
Packaging & Logistics
Sample Packing
1–5 kg aluminum foil bag; shipping charged.
Bulk Packing
Typically 25 kg/bag, carton, or drum with inner liner; moisture-protection options available on request.
Customization
Custom packaging, labeling, and export-mark discussion can be arranged according to destination and project needs.
Logistics & Documents
Packing configuration and supporting documents should be aligned before shipment to help meet handling, storage, and destination-market expectations.

FAQ
Do you supply Magnesium Glycinate / Magnesium Bisglycinate Powder in bulk?
Yes. Lifeworth supplies pure Magnesium Glycinate Powder for sample evaluation, pilot quantities, and commercial bulk orders, with standard export packaging and batch documentation support.
What does 99% mean for Magnesium Glycinate Powder?
The 99% specification should be understood together with the defined assay basis and test method. Buyers should review the TDS/specification and batch COA to confirm how Magnesium Glycinate or Magnesium Bisglycinate content is reported.
Is elemental magnesium content the same as the 99% assay?
No. Magnesium Glycinate assay and elemental magnesium content are different specification parameters. Elemental magnesium should be confirmed separately in the product specification or batch documentation for formulation and labeling calculations.
What documents can you provide?
Batch COA is available, while TDS/specification sheets and SDS/MSDS can be provided according to project requirements. Additional documentation can be reviewed based on the buyer’s destination market and application.
Can you support specific particle size or quality requirements?
Project-specific requirements such as particle size, assay basis, elemental magnesium, packaging, and selected quality limits can be reviewed according to the intended dosage form, order quantity, and destination market.
What is the bulk price of Magnesium Glycinate Powder?
Bulk pricing depends on order quantity, specification, packaging, and shipping destination. Please provide your required quantity and delivery location so we can prepare a project-based quotation.
