Name	Citric acid
Groups	approved nutraceutical vet_approved
Description	A key intermediate in metabolism. It is an acid compound found in citrus fruits. The salts of citric acid (citrates) can be used as anticoagulants due to their calcium-chelating ability. Citric acid is one of the active ingredients in Phexxi, a non-hormonal contraceptive agent that was approved by the FDA on May 2020.[L14120] It is also used in combination with magnesium oxide to form magnesium citrate, an osmotic laxative.[L43832]
Synonyms	Citric acid monohydrate Citric acid, anhydrous 2-hydroxy-1,2,3-propanetricarboxyic acid Citric acid 2-Hydroxytricarballylic acid 3-carboxy-3-hydroxypentane-1,5-dioic acid Citronensäure Citric acid monoglyceride Citric acid,anhydrous ácido cítrico Acidum citricum Anhydrous citric acid
