Warning about Ellagic Acid from raspberries

Another cancer useful compound found in berries is Ellagic Acid. It is most available in rasberries. But Ellagic Acid concentrations vary widely from manufacturer to manufacture. Actually, there seems to be some terrible misunderstandings about Ellagic Acid. This information should clear up the disinformation:

• Some manufacturers falsely claim that Ellagic Acid does not exist in nature and that only the Ellagitannin content is important. This is completely untrue.


• Ellagic Acid does exist in nature. The following plants contain free Ellagic Acid not just Ellagitannins: strawberry, walnut, guava, Chinese gall, grape, pomegranate and raspberry.


• Many web sites quote glowing results from the Cancer Prevention Program at Hollings Cancer Center, Medical University of South Carolina regarding the success of Ellagic Acid, but that study never mentions Ellagitannins.


• Some manufacturers list the amount of raspberry seed power in each capsule. Unprocessed raspberry seed power contains Ellagic Acid in the ridiculously small, cmg range (1000 cmg = one mg). Only purchase products that clearly display Ellagic Acid in the mg range. You can find products that have 20 to 840 mg of Ellagic Acid per pill.

For a table of manufacturers that shows the actual pill content of Ellagic Acid, go to the Manufacturers section of this Ellagic Acid page.
