Our brand Landnutra supplies a high‑purity bulk magnesium bisglycinate powder - a fully reacted amino acid chelate that pairs elemental magnesium with glycine molecules, standardized to ≥98% purity and delivering 14.0–18.0% magnesium content with a naturally sweet taste, engineered for superior gastrointestinal tolerance, rapid absorption, and predictable relaxation support without the laxative effect common to other magnesium forms. Produced via aqueous chelation under full cGMP, this fine white to cream‑colored powder dissolves easily in water, imparts no bitter aftertaste, and fits clean‑label capsules, powders, functional beverages, and sleep‑support formulations - the preferred choice for brands sourcing bulk magnesium bisglycinate powder with consistent quality and sensory performance.

01Superior Gastrointestinal Tolerance
The glycine chelate resists dissociation in the stomach, allowing intact absorption through dipeptide transporters in the small intestine - this eliminates the osmotic diarrhea and cramping typically associated with magnesium oxide or citrate.
02High Bioavailability & Rapid Uptake
Studies show magnesium bisglycinate achieves superior serum magnesium levels compared to inorganic salts, delivering more elemental magnesium per dose to muscle, nerve, and bone tissues.
03Natural Taste Masking
Inherent sweet‑neutral flavor profile eliminates the need for artificial maskers or flavors - formulators can reduce excipient cost and create cleaner labels, a critical advantage for stick packs and effervescent tablets.
04Promotes Relaxation & Sleep Quality
Glycine itself acts as an inhibitory neurotransmitter; combined with magnesium's NMDA‑antagonist and GABAergic effects, the chelate supports restful sleep, reduced muscle tension, and calm mood without next‑day grogginess.
05Supports Muscle Function & Bone Health
Adequate magnesium intake is essential for ATP‑driven muscle contraction and bone mineral density. Magnesium bisglycinate's high absorption makes it ideal for sports recovery and osteoporosis prevention formulas.
06Clean‑Label & Vegan
Produced from non‑GMO glycine and mineral sources, free of animal‑derived materials, suitable for vegan, Halal, Kosher, and allergen‑free supplement lines.
Application Fields
Dietary Supplements (Hero Application): Relaxation & sleep capsules, muscle recovery tablets, magnesium‑based anti‑stress formulas, daily multi‑mineral blends (typical dose 100–400 mg elemental Mg/day).
Functional Foods & Beverages: Powdered drink mixes, ready‑to‑drink relaxation shots, fortified protein bars, and effervescent tablets - where neutral taste and solubility matter.
Sports & Active Nutrition: Intra‑workout and recovery powders addressing muscle cramps and electrolyte balance, often paired with B‑vitamins and zinc.
Women's Health & Prenatal: Formulated into prenatal multis and PMS support products owing to its gentle digestive profile.
Production Process
High‑purity glycine is reacted with a magnesium source (oxide or carbonate) in a controlled aqueous environment, forming the bisglycinate chelate. The solution is filtered, concentrated, and crystallized under mild heat to preserve structural integrity. The crystals are vacuum dried, milled, and sieved to target particle size, then tested for potency, magnesium content, and microbiological safety - all within cGMP‑certified workshops.
Product Quality Advantage
Fully Reacted Chelate – No free magnesium oxide residues, verified by FTIR.
Neutral Taste & Aroma – Eliminates cost for taste‑masking excipients.
