Calcium citrate

Synonyms: Calcium citrate tribasic, Tricalcium citrate, Calcium salt of citric acid, E333, INS 333

Calcium citrate is the calcium salt of citric acid, a weak organic acid naturally found in citrus fruits. It is produced by neutralizing citric acid with a calcium source, such as calcium hydroxide or calcium carbonate, followed by filtration, drying, and milling. The result is a white, crystalline powder that is odorless and has a slightly alkaline taste. Commercially, it is available in various grades, including food grade, pharmaceutical grade (USP/EP/BP), and technical grade, with the pharmaceutical grade being the most relevant for supplement and medicinal applications.

In the B2B arena, calcium citrate has established itself as a preferred calcium source for dietary supplements, functional foods, and pharmaceutical formulations. Its superior bioavailability compared to calcium carbonate, especially in individuals with low stomach acid, makes it a go-to choice for formulators targeting bone health, women’s health, and senior nutrition. Beyond supplements, it serves as a buffering agent, sequestrant, and firming agent in food and beverage processing, and as a calcium source in medical nutrition and cell culture media. With the global push for clean-label and highly absorbable minerals, calcium citrate continues to gain traction in new product development.
