    bulk Calcium Citrate Usage and Synthesis.Citrato de Calcio en Polvo de Grado Alimentario (CAS 813-94-5) - Ausreson

    Amino acid calcium is a new source of calcium, as far as its chemical molecular composition is concerned, it is also an organic calcium, such as: L-threonate calcium, acid chelated calcium. How much calcium can be absorbed by the body is people's greatest concern. Absorption rate test shows that, containing 250 mg of elemental calcium of different calcium preparations and a standardised breakfast at the same time, the absorption rate were: malic acid, citric acid calcium salt 35%, calcium carbonate salt 27%, calcium phosphate salt 25%, the difference in the effect of calcium supplementation is not significant, but the cost-effectiveness of calcium carbonate is the most advantageous.Citrate de Calcium en Poudre de Qualité Alimentaire (CAS 813-94-5) - Ausreson

    Calcium Citrate is a calcium salt derived from citric acid, used as a nutritional supplement for the prevention and treatment of calcium deficiencies, for the promotion of dental and bone health, and as an aid to weight loss.Citrato de Cálcio em Pó de Grau Alimentício (CAS 813-94-5) - Ausreson

    Chelating agent, buffering agent, tissue coagulant, according to FAO/WHO (1984), the use and limit is: low concentrated milk, sweetened condensed milk, thin cream, etc. 2g/kg alone, and other stabilizers with other amounts of 3g/kg (in anhydrous matter); milk powder, cream powder 5g/kg; melting dry cooler manufacture of 40g/kg; jellies, canned tomatoes, cold drinks, cooler proteins, used as a GMP as When used as fortifier, the theoretical calcium content of the product is 21.07%, which can be used in flour, pastry, Japanese fermented bean paste, and the limit is 1% in Japan.

    Calcium Citrate vs Calcium CarbonateПищевой цитрат кальция в порошке (CAS 813-94-5) - Аусрезон

    Characteristics Calcium Citrate Calcium Carbonate
    Elemental Calcium Content Approximately 21% (Lower)
    • For example: 1000mg calcium citrate ≈ 210mg elemental calcium
    Approximately 40% (Higher)
    • For example: 1000mg calcium carbonate ≈ 400mg elemental calcium
    Absorption Rate Higher, unaffected by gastric acid. Absorption significantly superior to calcium carbonate when taken on an empty stomach.  Dependent on gastric acid. Well absorbed when taken with meals; absorption rate markedly reduced when taken on an empty stomach.
    Timing of intake May be taken at any time (fasting or with meals) Must be taken with meals
    Gastrointestinal side effects Generally mild, with lower likelihood of causing constipation or bloating. More common, more likely to cause constipation, bloating, and abdominal distension
    Cost Typically more expensive Highly economical, the most affordable form of calcium supplementation.
    Ideal for 1. Individuals with reduced gastric acid secretion (elderly, acid-suppressing medication users)
    2. Those with sensitive stomachs or prone to constipation
    3. Inflammatory bowel disease patients
    4. Irregular eaters
    1. Individuals with normal gastric acid secretion and healthy digestion
    2. Those seeking value for money
    3. Preferring smaller tablets (due to high calcium content)

    How to Choose Between Calcium Citrate and Calcium Carbonate

    You should choose Calcium Citrate if:

    • You typically take supplements between meals or on an empty stomach.
    • You are over 50 years of age.
    • You are taking acid-suppressing medication.
    • You frequently experience constipation or gastrointestinal discomfort from calcium carbonate.
    • You have malabsorption syndrome or inflammatory bowel disease.

    You may opt for Calcium Carbonate if:

    • Your digestive system is healthy and you can consistently take it with meals.
    • You have budget constraints and seek value for money.
    • You prefer smaller, fewer tablets (as fewer tablets are needed to achieve the same dosage).

    Calcium Citrate vs Calcium Carbonate

    Side effects of Calcium Citrate.

    Calcium Citrate is a calcium salt derived from citric acid and is used as a nutritional supplement for the prevention and treatment of calcium deficiencies, to promote healthy teeth and bones, and to aid in weight loss.

    Since it is soluble in water, it is the most easily absorbed form of calcium in the body. While there are many benefits, there are also some side effects.

    Common side effects include bloating, constipation and burping. If you experience constipation, nausea, vomiting, dry mouth or loss of appetite after taking calcium citrate, you should stop taking it immediately and contact your doctor.

    Serious side effects include difficulty breathing, difficulty swallowing, bone or muscle pain, severe weight loss, frequent urination, thirst, irregular heartbeat and weakness, etc. Emergency room visits should be made immediately for these symptoms.

    Calcium Citrate Raw Materials

    Product Method of  Bulk Calcium Citrate Powder.

    Use the milk of lime and citric acid solution, the reaction produces precipitation by filtration, washing, drying and finished products. Can also be used as raw materials for eggshells, after cleaning, crushing, water immersion washing, drying, and then dried at 110 ℃ for 1h, and then calcined at 1000 ℃ for 1h, made of water to the milk of lime; and then with 3.5 ~ 4.0 mol / L citric acid solution and neutralisation (citric acid is slightly overdosed), and then after precipitation, filtration, washing to Ph = 6 ~ 7, and finally at 110 ℃, drying for 1h to the finished product.

    FAQ.

    Q: What are the main differences between calcium citrate and calcium carbonate?

    A:

    Absorption method: Calcium citrate does not rely on gastric acid, whereas calcium carbonate requires gastric acid for effective absorption.

    Calcium content: Calcium carbonate (~40%) is higher than calcium citrate (~21%), meaning more calcium citrate powder is required to deliver the same amount of elemental calcium.

    Mildness: Calcium citrate is gentler and less likely to cause constipation; calcium carbonate carries a higher risk of gastrointestinal irritation.

    Applications: Calcium citrate is better suited for liquids, acidic foods, and on an empty stomach; calcium carbonate is lower cost and widely used in tablets.

    Q: What is the recommended daily dose? How should the amount be calculated?

    A: The recommended daily calcium intake for adults is approximately 1000 milligrams. When formulating, note that calcium citrate contains about 21% elemental calcium.

    Calculation formula: Required citrate calcium weight = Target elemental calcium weight / 21%

    Example: To deliver 300mg elemental calcium, approximately 300 / 0.21 = 1429mg citrate calcium powder is needed.

    Q: Does this powder affect product flavour?

    A: High-quality calcium citrate powder possesses a very mild, near-neutral flavour. It exerts minimal impact on the taste profile of most products and does not impart any unpleasant metallic or chalky taste.

    Q: What are the Minimum Order Quantity (MOQ) and sample policy?

    A: Our standard MOQ is 20 kilograms. We can provide paid samples of 1 kilogram to clients demonstrating genuine cooperation intent, for your application testing and formulation development purposes.
