LANDNUTRA Magnesium Glycinate Bulk Powder is a premium chelated mineral ingredient in which each magnesium ion is bound to two glycine molecules, yielding an elemental magnesium content of 14.0–18.0% with zero free magnesium oxide. Engineered for contract manufacturers and brand owners, this pure bisglycinate chelate delivers superior tolerance and absorption - eliminating the osmotic diarrhea commonly associated with oxide- and citrate-based formulas.
As a direct manufacturer with 15+ years of amino acid chelation expertise, LANDNUTRA offers two physical grades: a fine-flow crystalline powder (≥95% through 80 mesh) for direct-fill capsules and tablets, and an instantized agglomerate that disperses in cold water within 15 seconds with minimal dusting. Every batch is verified by HPLC, ICP-MS, FTIR, and LAL endotoxin testing - with full documentation including COA, MSDS, and stability data. We serve global markets as a trusted supplier of genuine magnesium bisglycinate, backed by cGMP, ISO, Halal, and Kosher certifications.

Product Benefits
Why Formulators Choose Magnesium Glycinate
No Laxative Effect, No Formulation Compromises
Absorbed intact through dipeptide transporters without drawing water into the colon. You can deliver 200–400 mg of elemental magnesium per serving without the digestive complaints that cause consumers to abandon products.
01
Predictable Absorption in Multi-Mineral Blends
Unlike ionized magnesium salts that compete with calcium, zinc, and iron for transport, the intact dipeptide chelate is absorbed independently - simplifying the design of high-potency mineral complexes.
02
Endotoxin-Controlled for Sensitive Applications
Every batch is tested by LAL assay and consistently measures below 0.1 EU/mg - well below USP limits - making the powder suitable for infant formula, enteral nutrition, and hypoallergenic products.
03
Instantized Grade Cuts Processing Time
The agglomerated version pours cleanly, disperses in cold water within 15 seconds, and reduces the need for high-shear mixing - saving energy and time on your production floor.
04
Third-Party Verified Chelation Integrity
We include FTIR and XRD data in the COA to prove the product is genuine magnesium bisglycinate - not a physical blend of magnesium oxide and glycine - protecting your brand from label-claim disputes.
05
Production Process
Manufacturing Workflow: Glycine + Magnesium Carbonate → Reaction & Chelation → Purification & Crystallization → Spray Drying or Crystallization → Sieving & Blending → Quality Control Testing → Packaging.
Every batch is produced in our dedicated chelation suite under cGMP standards, with in-process controls and final release testing to ensure consistent quality and full traceability from raw materials to finished bulk powder.

FAQ
Q: How do you guarantee the powder is true magnesium bisglycinate, not just a blend of oxide and glycine?
A: We provide FTIR and XRD spectra with every batch. These techniques clearly distinguish the chelate from a physical mixture. Free MgO is also quantified by XRD and consistently below 0.2%.
Q: Does this magnesium cause diarrhea?
A: No. It is absorbed intact through dipeptide transporters and does not exert an osmotic effect in the gut - even at doses of 400 mg elemental magnesium.
Q: What is the advantage of the instantized grade?
A: The agglomerated powder disperses in cold water within 15 seconds with minimal dust, making it ideal for stick packs and ready-to-drink powders where rapid dissolution is critical.
Q: Is the endotoxin level controlled?
A: Yes. Every batch is tested by LAL assay and consistently measures below 0.1 EU/mg - well below the USP limit for oral products.
Q: What are your MOQ and sample policy?
A: MOQ is 1 kg. Free samples are available for qualified inquiries. We ship samples within 48 hours and provide full documentation with every shipment.
