Ellagic acid is a naturally occurring polyphenol found in berries, pomegranates, walnuts, and oak-aged wines. It’s the compound behind many of the health benefits attributed to these foods, from antioxidant defense to cellular protection. Chemically, it’s a dilactone of hexahydroxydiphenic acid, and it’s gaining traction in the nutraceutical and pharmaceutical industries for its potential in skin health, cardiovascular support, and chemoprevention.
Synonyms: 2,3,7,8-Tetrahydroxy[1]benzopyrano[5,4,3-cde][1]benzopyran-5,10-dione, Gallogen, Benzoaric acid, Lagistase, Alizarin yellow
You’ll find ellagic acid in raspberries, strawberries, and pomegranates, but commercial production relies on richer sources like oak bark, chestnut wood, and pomegranate husk. The extraction process typically involves solvent extraction followed by purification and crystallization to achieve the desired purity.
One challenge with ellagic acid is its poor oral bioavailability. It’s rapidly metabolized in the gut, so formulators often use micronized or complexed forms to enhance absorption. Our high-purity ellagic acid is designed to be stable and bioavailable, making it suitable for supplements and functional foods.
Our ellagic acid is derived from pomegranate husk, extracted with a green solvent process, then concentrated and purified to meet your target specs. We offer various grades from 40% to 98% purity, each batch tested by HPLC and shipped with a full COA. Whether you need a small sample or bulk drums, we’ve got you covered.
Ellagic acid is generally recognized as safe when used in appropriate amounts. It’s been studied in clinical trials for its antioxidant and anti-inflammatory effects, with no significant adverse effects reported at typical supplement doses. As with any ingredient, we recommend consulting a healthcare professional for specific use cases.
