Calcium Lactate (Calcium Lactate, CAS 814-80-2) is an organic calcium salt with high bioavailability, produced by neutralizing natural lactic acid with a calcium source.
It appears as a white crystalline powder or granular product, featuring high solubility, neutral taste, excellent absorption rate and low gastrointestinal irritation.
As a generally recognized safe (GRAS) food additive and nutritional fortifier, calcium lactate is widely used in food & beverages, dietary supplements, pharmaceutical preparations and personal care products.
It is an ideal raw material for “high-calcium” product claims and calcium nutrition supplementation.

Key Application Fields
1. Food & Beverage Industry
Calcium Nutritional Fortifier: Added to fruit juices, plant protein drinks, modified milk, milk powder, infant foods, grain products, bakery pastries, etc., to support "high-calcium" nutritional claims.
Recommended dosage: 12–24 g/kg for grain products, 23–46 g/kg for infant foods.
Acidity Regulator & Stabilizer: Used in jellies, jams, canned tomatoes, etc., to adjust pH and improve gel texture.
Recommended dosage in jelly: 3–6 g/kg.
Quality Improver: Used in bread and pastries as a buffer and leavening agent to enhance product structure.
2. Health Food & Dietary Supplements
High-Bioavailability Calcium Source: Serves as a core calcium supplement ingredient for tablets, capsules, granules, and oral liquids, with high absorption rate and low gastrointestinal irritation.
Formulations for Special Groups: Suitable for calcium supplement products for children, pregnant women, lactating women, menopausal women, and the elderly.
3. Pharmaceutical Industry
Calcium Supplement Drugs: Used for the prevention and treatment of calcium deficiency disorders, such as osteoporosis, tetany, rickets, and bone hypoplasia.
Pharmaceutical Excipients: Used as tablet filler or stability-improving excipient.
4. Personal Care & Other Fields
Oral Care: Used in toothpaste formulations to help strengthen tooth enamel.
Fruit & Vegetable Preservation: Used for color protection and preservation of fresh-cut fruits and vegetables.
Pet Food: Applied as a calcium nutritional fortifier.
