Product Info
What is Magnesium Lactate?
Magnesium lactate is a highly bioavailable magnesium salt of lactic acid, primarily utilized as a dietary supplement, mineral fortifier, and acidity regulator in foods and beverages.
How is Magnesium Lactate made?
| Step No. | Production Stage | Key Action | Control Point & Note |
|---|---|---|---|
| 1 | Synthesis / Reaction | React Lactic Acid with a magnesium source (e.g., Magnesium Oxide or Carbonate) in purified water inside a glass-lined or stainless steel reactor. | Control Point: Monitor reaction temperature and pH level (typically target is 6.0-8.0) to ensure complete neutralization. Note: The purity of raw materials is critical for the final product quality. |
| 2 | Purification & Decolorization | Filter the resulting magnesium lactate solution. Add activated carbon to the solution, heat, and stir to remove color and organic impurities. | Control Point: Dosage of activated carbon and filtration clarity. Note: This step significantly improves the color and purity of the final product. A second filtration removes the carbon. |
| 3 | Concentration | Transfer the clear filtrate to an evaporator and heat under vacuum to remove excess water, concentrating the solution to a specific density. | Control Point: Monitor the solution concentration (specific gravity) and vacuum/temperature levels carefully. Note: Over-concentration can lead to premature or uncontrolled crystallization. |
| 4 | Crystallization | Cool the concentrated solution under a controlled program with slow agitation to induce the formation of magnesium lactate crystals. | Control Point: The cooling rate is paramount. Note: A slow, controlled cooling curve promotes the growth of larger, more uniform crystals, which are easier to process. |
| 5 | Separation & Washing | Separate the crystal slurry from the mother liquor using a centrifuge. The resulting crystal "wet cake" may be washed with a small amount of cold purified water. | Control Point: Centrifuge speed and time. Note: Washing helps remove residual impurities trapped on the crystal surface. |
| 6 | Drying | Dry the washed crystals in a suitable dryer (e.g., fluid bed or vacuum dryer) at a controlled temperature until the required moisture content is reached. | Control Point: Crucial to monitor drying temperature and final moisture content (Loss on Drying). Note: Excessive heat can cause product degradation or discoloration. |
| 7 | Sieving & Blending | Sieve the dried product through a screen of a specified mesh size to achieve a uniform particle size distribution. Blend the entire batch for homogeneity. | Control Point: Verify sieve mesh integrity and final particle size analysis. Note: This step ensures the final product has consistent physical properties. |
| 8 | Final QC & Packaging | Take a representative sample for final quality control testing against all specifications (e.g., assay, heavy metals, microbial limits). Package approved product into clean, sealed containers. | Control Point: Full compliance with product specifications. Note: Proper packaging and labeling with batch numbers are essential for product integrity and traceability. |

Applications & Usage
Common Applications:
magnesium supplementation in foods
beverages
nutritional products
acidity regulation
Mechanism of action:
| Parameter | Magnesium Lactate |
|---|---|
| Functional Category | Nutrient Supplement; Acidity Regulator; pH Control Agent; Firming Agent. |
| Key Ingredients | Magnesium Lactate (magnesium salt of lactic acid). |
| Mechanism of Action | Provides a highly bioavailable source of elemental magnesium for nutritional fortification. As an acidity regulator, the lactate anion acts as a weak base to buffer pH, neutralizing excess acids. Can interact with pectins in plant tissues, cross-linking chains to enhance structural integrity and firmness. |
| Application Effect in Product | Nutritionally enriches products like beverages, supplements, and dairy with magnesium. Stabilizes pH in confectionery and beverages, preventing unwanted texture or flavor shifts. Improves firmness and texture in canned fruits and vegetables. Contributes a mild saline taste, balancing the overall flavor profile without adding significant sourness. |
Comparison:
| Product Name | Category/Type | Key Features | Strengths (vs peers) | Weaknesses (vs peers) | Best Use Cases | Why Choose |
|---|---|---|---|---|---|---|
| Magnesium Lactate | Organic Magnesium Salt | Magnesium bound to lactic acid; moderate elemental magnesium. | Very gentle on the digestive system; good bioavailability; less likely to cause diarrhea than citrate or oxide. | Less common and can be more expensive than citrate or oxide; not ideal for laxative effect. | Supplementing high doses without digestive issues; for individuals with sensitive stomachs. | You need effective, well-absorbed magnesium and are sensitive to the laxative effects of other forms. |
| Magnesium Citrate | Organic Magnesium Salt | Magnesium bound to citric acid; good bioavailability. | Widely available, cost-effective, well-absorbed; effective for constipation relief. | Strong laxative effect at moderate to high doses; can cause digestive discomfort. | General supplementation for those not prone to loose stools; effective constipation relief. | You want a common, affordable, and effective all-around option and can tolerate its digestive effects. |
| Magnesium Glycinate | Magnesium Chelate | Magnesium bound to the amino acid glycine; high bioavailability. | Extremely gentle on the stomach with virtually no laxative effect; glycine may promote calmness and sleep. | Often more expensive; pills can be larger due to the size of the glycine molecule. | Correcting a deficiency without any digestive side effects; use for relaxation or sleep support. | You need the gentlest form with the highest absorption and want to avoid all laxative effects. |
| Magnesium Oxide | Inorganic Magnesium Salt | High percentage of elemental magnesium by weight. | Inexpensive and widely available in small tablets or capsules. | Very poor bioavailability (absorbs poorly); strong and often unpredictable laxative effect. | Short-term use as an antacid for heartburn or as a potent laxative. Not effective for correcting deficiency. | You are seeking a low-cost antacid or strong laxative, not an efficient way to increase magnesium levels. |
| Magnesium Malate | Organic Magnesium Salt | Magnesium bound to malic acid; good bioavailability. | Well-absorbed and gentle on the digestive system; malic acid is involved in cellular energy production. | Less common than citrate or oxide; may be slightly more expensive. | General supplementation; may be beneficial for muscle fatigue and energy support. | You want a well-absorbed form that is gentle on the stomach and may also help with energy levels. |
