Magnesium Lactate

Magnesium lactate is a magnesium salt of lactic acid providing approximately 12% elemental magnesium by weight, used as both a dietary supplement and approved food additive (E-329). It delivers magnesium ions upon dissociation in the gastrointestinal tract, supporting enzymatic reactions, nerve conduction, and muscle function.

Origin & History

Magnesium lactate is the magnesium salt of lactic acid, appearing as white granules or crystals. It is produced synthetically by neutralizing lactic acid (derived from fermentation of sugars by bacteria like Lactobacillus) with magnesium compounds such as magnesium oxide or hydroxide.

Historical & Cultural Context

No historical or traditional medicine uses are documented in the research dossier. The compound appears to be a modern synthetic preparation used primarily in food and supplement industries.

Health Benefits

• No clinical trials or health benefit studies were found in the research dossier
• The compound is approved as a food ingredient and nutrient source (FDA UNII MT6QI8324A, E-329)
• Contains 11.8-12.2% elemental magnesium in anhydrous form for supplementation
• Used as a buffering agent and dough conditioner in food applications
• No evidence-based health claims can be made from the available research

How It Works

Upon ingestion, magnesium lactate dissociates into Mg²⁺ ions and lactate anions in the gastrointestinal tract; Mg²⁺ is absorbed primarily via TRPM6 and TRPM7 transient receptor potential channels in intestinal epithelial cells. Intracellular magnesium acts as a cofactor for over 300 enzymatic reactions including ATP synthase, adenylyl cyclase, and DNA polymerase. The lactate counterion may modestly enhance solubility at gastric pH compared to oxide forms, potentially improving passive paracellular absorption.

Scientific Research

The research dossier contains no human clinical trials, RCTs, or meta-analyses on magnesium lactate. No PubMed PMIDs or study details regarding efficacy are available in the sources, which focus exclusively on chemical properties rather than health outcomes.

Clinical Summary

No dedicated randomized controlled trials specifically evaluating magnesium lactate as an isolated intervention have been identified in the published literature. General magnesium bioavailability research suggests organic magnesium salts such as lactate and citrate demonstrate modestly superior intestinal absorption compared to inorganic forms like magnesium oxide, though head-to-head data specific to the lactate form are limited. The compound's regulatory approval as FDA UNII MT6QI8324A and European food additive E-329 reflects safety evaluation rather than efficacy evidence. Clinical conclusions about therapeutic benefit for magnesium lactate specifically cannot be drawn without dedicated human trials.

Nutritional Profile

Magnesium Lactate is a magnesium salt of lactic acid, functioning primarily as a concentrated mineral source. Elemental magnesium content: 11.8–12.2% by weight in anhydrous form (dihydrate form contains approximately 10.6% elemental magnesium). A typical 500 mg dose of magnesium lactate dihydrate delivers approximately 53–61 mg of elemental magnesium, representing ~13–15% of the adult daily recommended intake (RDA: 310–420 mg/day depending on age and sex). Contains no meaningful macronutrients (protein, fat, or carbohydrates) at supplemental doses. The lactate anion (C3H5O3−) constitutes the remainder of the molecular weight (MW: 202.98 g/mol for dihydrate); lactate is a naturally occurring organic acid metabolite in human physiology and does not contribute caloric load at typical supplement doses. Bioavailability: Organic magnesium salts such as magnesium lactate are generally considered more bioavailable than inorganic forms (e.g., magnesium oxide, ~4% absorption) due to enhanced solubility in gastrointestinal fluid; absorption estimates for organic forms range from 30–50% under fasting conditions via passive paracellular and active transcellular transport in the small intestine (TRPM6/TRPM7 channels). The lactate carrier may facilitate intestinal absorption by reducing gastric irritation compared to inorganic salts. No vitamins, fiber, or additional bioactive compounds are present.

Preparation & Dosage

No clinically studied dosage ranges are available in the research. The compound exists in anhydrous form (11.8-12.2% magnesium content) and trihydrate form. Consult a healthcare provider before starting any new supplement.

Synergy & Pairings

No synergistic ingredients identified in research

Safety & Interactions

Magnesium lactate is generally recognized as safe at food-additive concentrations; supplemental doses exceeding 350 mg elemental magnesium daily from non-food sources may cause osmotic diarrhea, nausea, and abdominal cramping. Magnesium can reduce absorption of fluoroquinolone antibiotics (e.g., ciprofloxacin), tetracyclines, and bisphosphonates by forming insoluble chelate complexes, requiring a minimum 2-hour separation between doses. Individuals with chronic kidney disease or renal insufficiency risk hypermagnesemia due to impaired urinary magnesium excretion and should avoid supplemental magnesium without medical supervision. No specific teratogenicity has been identified, but high-dose intravenous magnesium in late pregnancy is associated with neonatal hypermagnesemia; oral supplemental use at moderate doses is generally considered acceptable during pregnancy.
