Product Overview
Magnesium Oxide Powder is an inorganic magnesium compound commonly used in supplement, food, pharmaceutical-oriented, premix, and industrial sourcing projects.
It is usually supplied as a white powder under USP, EP, FCC, or agreed specifications, and buyers often review MgO assay, grade type, particle size, heavy metals, loss on ignition, and destination-market limits before technical or commercial evaluation.
It is commonly considered for tablets, mineral premixes, selected fortified products, and industrial processing applications, with COA, SDS/MSDS, TDS/spec sheet, sample support, and export documents available for sourcing reference.
Applications
Dietary Supplements
Magnesium oxide powder is widely used as a high-magnesium-content mineral source in tablets, capsules, and mineral supplement formulas. Buyers should review MgO assay, elemental magnesium calculation, particle size, and local supplement regulations before formulation.
Food & Nutrition Premixes
It can be considered for selected fortified food, nutrition powder, and premix systems where mineral content, dosage uniformity, heavy metals, and food-grade documentation are required. Pilot blending is recommended before scale-up.
Pharmaceutical-Oriented Tablets
Magnesium oxide may be used in pharmaceutical-oriented oral systems where USP, EP, or other pharmacopoeial requirements are reviewed. Grade, assay basis, impurity limits, and release testing should be confirmed before sourcing.
Industrial & Processing Applications
Industrial-grade magnesium oxide may be used in refractory, ceramics, rubber, plastics, fillers, agriculture blends, and process applications. For these uses, particle size, activity, purity, density, and application-specific limits are more important than food or supplement documentation.
Technical & Formulation Notes
Technical Notes
Magnesium oxide should be evaluated according to MgO assay, grade type, particle condition, and the intended application. For food, supplement, or pharmaceutical-oriented use, buyers should confirm the applicable standard, release limits, heavy metals, microbiology requirements, and documentation package before purchase.
Manufacturing & Process
Commercial magnesium oxide is commonly produced by calcining magnesium carbonate or magnesium hydroxide, followed by cooling, milling, grading, and in-process quality control. Process conditions can influence activity, bulk density, particle size, loss on ignition, and downstream formulation behavior.
Compatibility / Formulation Notes
- For tablets and capsules, review particle size, bulk density, flowability, and compression behavior before scale-up.
- For premixes and fortified products, validate blending uniformity, dosage accuracy, heavy metals, and compatibility with other minerals or excipients.
- For industrial applications, confirm mesh size, activity, density, impurity profile, and process-specific performance requirements before bulk purchase.
- Magnesium oxide has low solubility in water and may react with acids, so solubility and pH behavior should be validated in the final system.
- Keep the material sealed and dry during storage, handling, and repacking to reduce moisture absorption and caking risk.
Extended QC & Test Items
Common extended review items include appearance, identification, MgO assay, loss on ignition, acid-insoluble substances, soluble salts, particle size, bulk density, heavy metals, microbiology where applicable, and batch traceability. For industrial or specialty-grade use, activity, mesh size, D50/D97, and application-specific impurities may also need review.

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 and direct sunlight. Reseal immediately after opening.
Moisture control is recommended during transit and warehouse operations (e.g., desiccant when applicable).
Shelf Life
24 months from the manufacturing date when stored in the original, unopened packaging under recommended conditions. Refer to the COA/batch label for the exact retest/expiry information.
