Calcium Citrate for Efficient Calcium Supplementation
Calcium Citrate is an organic calcium salt known for its good absorption and gentle digestive profile. Unlike calcium carbonate, its absorption is less dependent on stomach acid, making it a suitable calcium source for people with low stomach acid or sensitive digestion.
It can be taken with or without food and is generally less likely to cause digestive discomfort or constipation. Calcium citrate is widely used in dietary supplements to help meet daily calcium needs and support healthy bones and teeth. Some formulations are also combined with Vitamin D3 to support calcium utilization.
For specific applications, calcium citrate can be supplied in various forms, including tablets, capsules, chewable tablets, and oral solutions.

What Are The Benefits?
Gentle on the Digestive System
Calcium citrate is less dependent on gastric acid for absorption than calcium carbonate, making it a suitable calcium source for people with lower stomach acid or sensitive digestion. It can be taken with or without food and does not release carbon dioxide in the digestive tract, which may help
reduce common digestive discomfort such as bloating and belching.
Good Calcium Absorption
Calcium citrate offers reliable calcium absorption across a range of dietary conditions and can be effectively absorbed when taken either with meals or between meals. This makes it a versatile calcium source for dietary supplements and nutritional products.
High Calcium Content
Calcium citrate provides approximately 21% elemental calcium, offering a concentrated source of calcium compared with several other organic calcium salts. Its relatively high calcium content makes it suitable for calcium-fortified foods, beverages, and dietary supplements.
Supports Bone & Dental Health
Calcium is an essential mineral for maintaining normal bones and teeth. Regular calcium intake, together with adequate vitamin D and a balanced diet, helps support bone mineralization, bone strength, and overall skeletal health throughout life.
Suitable for Calcium Supplementation
Calcium citrate is widely used as an ingredient in calcium supplements, multivitamins, functional foods, and nutritional formulations. Its good absorption profile and digestive tolerance make it a practical choice for a variety of consumer and professional nutrition products.
Supports Normal Muscle & Nerve Function
Calcium plays an important role in normal muscle contraction and nerve transmission. Adequate calcium intake helps maintain normal physiological functions and supports the body's nutritional needs during daily activities and physical exercise.
Good Biocompatibility
Calcium citrate has good biocompatibility and is widely studied for nutritional and biomedical applications. Its calcium ions can contribute to normal mineral metabolism and support the body's physiological processes related to bone health.
What Are The Application Directions?
Food industry: It is widely used in the food industry as a food additive. It is often used in beverages and foods such as juices, carbonated drinks, jelly, and candies to increase their acidity and taste, promote food preservation, and prevent bacterial growth. Calcium citrate can also be used as melting salt and buffering agent in the processing of dairy products, bread, pastries and other foods.
Pharmaceutical manufacturing: used in the pharmaceutical field as an auxiliary ingredient for drugs. It is often used in the manufacture of chewable tablets, vitamin tablets, capsules and other medicines to provide calcium supplementation and improve the taste of medicines. Calcium citrate is also used in the manufacture of antacids and acid neutralizers to help adjust the acid-base properties of drugs.
Health products: Bulk Calcium Citrate, as an ingredient in nutritional health products, is widely used in products to supplement calcium and maintain bone health. Oral calcium citrate supplements can provide the calcium needed by the body to prevent and improve osteoporosis, fractures and other problems. Calcium citrate is also often added to vitamin and mineral complexes to increase their nutritional value.

Feed additives: used as feed additives in animal husbandry. It can provide the calcium needed by animals, promote animal bone development and dental health, and improve animal production performance and immunity. Calcium citrate can also be used as a buffer to adjust the acid-base balance of the feed and improve the stability of the feed.
Cosmetics: Often found in cosmetic products as regulators and acid-base balancers. It helps adjust the acidity and alkalinity of cosmetics, maintain appropriate pH values, and improve product stability and shelf life. Calcium citrate can also be used as an antioxidant in skin care products to reduce free radical damage to the skin.
