2. Introduction of magnesium lactate

Magnesium lactate is a magnesium salt of lactic acid, widely used in the food, dietary supplement, and nutraceutical industries due to its excellent bioavailability and mild taste. As a food-grade ingredient, it serves as a magnesium fortifier, pH regulator, and stabilizer in various products.

2.1. General Characteristics

Chemical Name: Magnesium lactate
CAS Number: 18917-93-6 (anhydrous), 179308-96-4 (dihydrate)
Molecular Formula: C₆H₁₀MgO₆ (anhydrous), C₆H₁₀MgO₆·2H₂O (dihydrate)
Appearance: White or off-white crystalline powder
Solubility: Highly soluble in water, slightly soluble in ethanol
Odor & Taste: Odorless with a slightly bitter or neutral taste

2.2. Physical & Chemical Properties

Melting Point: Decomposes before melting
pH (in solution): ~6.0–8.0 (mildly acidic to neutral)
Hygroscopicity: Moderately hygroscopic (should be stored in a dry environment)
Stability: Stable under normal conditions but may degrade under extreme heat or pH

3. Applications of magnesium lactate in Food and Nutraceuticals

3.1. Food Industry

Mineral Fortification: Added to beverages, dairy products, and baked goods to enhance magnesium content.
Acidity Regulator: Used in processed foods to adjust pH and improve texture.
Preservative & Stabilizer: Extends shelf life in certain food products.

3.2. Dietary Supplements & Nutraceuticals

Magnesium Supplement: Provides a highly bioavailable form of magnesium, supporting muscle function, nerve transmission, and bone health.
Sports Nutrition: Included in electrolyte drinks and recovery formulations to prevent cramps and fatigue.
Functional Foods: Incorporated into health-focused products like fortified cereals, energy bars, and meal replacements.

4. Advantages Over Other Magnesium Salts

Better Absorption: Compared to magnesium oxide, it has higher bioavailability.
Gentle on Stomach: Less likely to cause digestive discomfort than magnesium citrate or sulfate.
Neutral Taste: Suitable for flavor-sensitive applications.

5. Safety & Regulatory Status

Magnesium lactate is generally recognized as safe (GRAS) by the FDA and approved for use in food and supplements in many countries, including the EU (E329) and the US.

Food-grade magnesium lactate is a versatile and effective magnesium source widely used in functional foods, supplements, and processed products. Its excellent solubility, bioavailability, and mild taste make it a preferred choice for manufacturers aiming to enhance nutritional profiles without compromising product quality.
