Description of Calcium citrate
Calcium citrate is the calcium salt of citric acid. It is also found in some dietary calcium supplements (e.g. Citracal). Calcium makes up 21% of calcium citrate by weight. white powder or white to colourless crystals.It is commonly used as a food additive (E333), usually as a preservative, but sometimes for flavor. In this sense, it is similar to sodium citrate. Calcium citrate is also used as a water softener because the citrate ions can chelate unwanted metal ions.
Application and Function of Product
Calcium citrate, a naturally occurring chemical in most plants and animals, is the calcium salt derived from citric acid. Calcium citrate is present in foods which have naturally occurring citric acid. Calcium citrate is used as a calcium supplement and may be used to treat conditions caused by low calcium levels such as bone loss (osteoporosis), weak bones (osteomalacia/rickets), decreased activity of the parathyroid gland (hypoparathyroidism), and a certain muscle disease (latent tetany). Calcium citrate may be chemopreventive for colon and other cancers. Calcium citrate is used as an ingredient in dietary supplements, and as a nutrient, sequestrant, buffer, antioxidant, firming agent, acidity regulator (in jams and jellies, soft drinks and wines), as a raising agent and an emulsifying salt. It is also used to improve the baking properties of flours and as a stabilizer.
Biological Activity
In many individuals, bioavailability of calcium citrate is found to be equal to that of the cheaper calcium carbonate.However, alterations to the digestive tract may change how calcium is digested and absorbed. Unlike calcium carbonate, which is basic and neutralizes stomach acid, calcium citrate has no effect on stomach acid. Individuals who are sensitive to antacids or who have difficulty producing adequate stomach acid should choose calcium citrate over calcium carbonate for supplementation. According to recent research into calcium absorption after gastric bypass surgery , calcium citrate may have improved bioavailability over calcium carbonate in Rouxen- Y gastric bypass patients who are taking calcium citrate as a dietary supplement after surgery. This is mainly due to the changes related to where calcium absorption occurs in the digestive tract of these individuals.
