Magnesium glycerophosphate, an organic magnesium salt produced from glycerophosphoric acid and magnesium sources, features a glycerophosphate anion that serves as a chelating carrier and supplies both magnesium and phosphorus within the same molecule.
Magnesium participates in over 300 enzymatic reactions, yet dietary surveys indicate that a substantial proportion of the population does not meet recommended intake levels.
Although green leafy vegetables, nuts, and whole grains are magnesium-rich, soil depletion, food processing, and cooking losses compromise dietary adequacy.
For individuals with higher physiological demands or reduced absorption capacity, supplementation becomes a practical consideration.
Magnesium glycerophosphate combines good bioavailability with gastrointestinal tolerability, finding application across dietary supplements, functional foods, beverages, oral care, and animal nutrition.

Frequently Asked Questions (Q&A)
Q1: What are the specified limits for magnesium content?
Pharmacopoeial specification (BP/Ph. Eur.) requires magnesium content between 11.0% and 12.5% on a dried basis. Commercial food-grade products with approximately 10.5% magnesium are also available.
Q2: What is the aqueous solubility profile?
Solubility in water at 20°C varies by product grade: some variants exceed 100 g/L, others fall within the 10–100 g/L range, and certain grades are below 1 g/L. The 1% aqueous solution pH ranges from 7.0 to 8.5.
Q3: Which pharmacopoeial monographs are applicable?
The compound is monographed in the British Pharmacopoeia (BP 2025), European Pharmacopoeia (Ph. Eur. 11.6 update), and Korean Pharmacopoeia (KP).
Q4: What is the recommended storage period and conditions?
Storage: kept well closed, dry, and at room temperature. Retest period: 36 months for all commercial grades.
Q5: How does the material behave with other formulation components??
Neutral taste and odour profile permits incorporation into complex formulations without sensory interference. The glycerophosphate moiety is reported to be compatible with probiotic strains such as Lactobacillus rhamnosus.
Q6: Is there any interaction with concurrently administered substances?
Separation from certain oral medications (tetracyclines, quinolones, nitrofurantoin, iron preparations, bisphosphonates, and penicillamine) is generally advised. A 2–4 hour interval between administrations is recommended to minimise absorption interference.
