⚖️ Formulation note: Magnesium Citrate Anhydrous is a mineral ingredient. For supplements, beverages or nutrition products, calculate dosage using elemental magnesium, not total powder weight. Typical anhydrous trimagnesium citrate contains approximately 16.2% elemental magnesium; confirm the exact value on the batch COA.

Benario Magnesium Citrate Anhydrous USP is a high-purity magnesium citrate powder for food, nutrition and supplement formulation. It is used as a magnesium source in capsules, tablets, powder blends, drink mixes, functional foods and mineral-fortified products. The anhydrous form provides a higher magnesium contribution per gram than many hydrated citrate forms, making it useful where compact formulation and mineral loading are important.

Benario is a trading name/food ingredient brand backed by AuSaMicS Pty Ltd (ABN 56 676 640 467). This product is supplied as a food/nutrition ingredient for formulation use. It is not supplied as a finished therapeutic good and is not intended to diagnose, treat, cure or prevent any disease. Final formulation, dosage, claims and label compliance are the buyer’s responsibility.

Magnesium Citrate Anhydrous USP is typically used where a clean magnesium source is required in dry blends, capsules, tablets, drink powders and fortified food products. Because magnesium citrate contributes both magnesium and citrate, formulators should consider taste, pH, solubility, mineral dosage and finished-product labelling.

🧮 Elemental magnesium calculation: As a practical guide, 1g of anhydrous trimagnesium citrate provides approximately 162mg elemental magnesium. Always use the batch COA or your formulation specification for final commercial dosage calculations.
Typical formulation use
Application Typical approach Notes
Capsules Calculate by elemental magnesium target Blend with suitable excipients and flow aids as required
Tablets Use according to compression formula Check flow, compressibility and taste masking
Powdered drink mixes Use at low to moderate mineral levels Citrate taste and solubility must be tested in final formula
Protein / nutrition powders Blend into dry premix Account for total magnesium from all ingredients
Fortified foods Use based on nutrition panel target Verify regulatory limits and permitted claims before launch
R&D / pilot batches Start with small trials Check flavour, mouthfeel, dispersibility and stability
Magnesium citrate vs other magnesium salts
Ingredient Typical use Key formulation point
Magnesium Citrate Anhydrous Supplements, beverages, fortified powders Citrate form; approx. 16.2% Mg; taste needs checking
Magnesium Citrate Hydrated Supplements and mineral blends Lower elemental magnesium per gram due to water of hydration
Magnesium Glycinate Premium supplement formulas Often used where gentler positioning is desired
Magnesium Oxide High-magnesium tablets/capsules High Mg percentage but lower solubility
Magnesium Malate Powders and supplement blends Organic acid salt with different flavour profile
Tips for use
  • Use a precise scale — magnesium ingredients are dosage-sensitive in nutrition products
  • Calculate using elemental magnesium, not the total magnesium citrate powder weight
  • Blend thoroughly into dry premixes to avoid hot spots in mineral content
  • Test taste in beverage powders — citrate/mineral notes can become noticeable at higher levels
  • For capsules/tablets, validate flow, density, compressibility and excipient compatibility
  • For commercial launch, verify permitted nutrition claims, dosage and warning statements with a qualified regulatory adviser
Storage
  • Store in a cool, dry place away from direct sunlight
  • Keep container tightly sealed after opening
  • Protect from moisture to reduce clumping and maintain flow
  • Use clean, dry utensils only
  • Keep away from strong acids, strong bases and incompatible materials

Usage information is general formulation guidance only. Magnesium intake, supplement dosage, permitted claims and warning statements vary by market and product type. This ingredient is not a finished supplement or therapeutic product. Final label compliance is the buyer’s responsibility.

Specifications represent typical information for Magnesium Citrate Anhydrous USP. Batch-specific values must be confirmed by Certificate of Analysis. Magnesium citrate naming can vary between hydrate and salt forms; always confirm CAS, assay and elemental magnesium against the supplied COA.

Magnesium Citrate Anhydrous USP is a food/nutrition ingredient with low hazard under normal dry-powder handling. The main safety considerations are dust control, eye irritation, moisture protection, accurate dosage and avoiding inappropriate therapeutic or medical claims.

⚠️ Dosage caution: Magnesium ingredients can contribute significant elemental magnesium. Excessive supplemental magnesium may cause gastrointestinal effects and other adverse effects. Finished products should be formulated and labelled by a qualified person according to the intended market and product category.
