Hey there

Everyone is talking about the acai berry!  I am going to strongly suggest that you ask your doctor to make sure but since this is a fruit...I wouldn't think there would be problems but it would be wise to get things checked out first by your doctor. 

I have read from sites which sell the extract that there aren't really any side effects or interactions with other drugs but I wouldn't know if I could trust that information.  In this article entitled, "Acai Berries-The Rock Star of the Berry World", they say this about the berry: 

"Another great benefit is that there are minimal side effects that have been reported with ingesting acai berries. It is a fruit and not some manmade compound. Your body responds to acai berries in the same way that it would with any other fruit or natural products. There should not be any shock to your system or initial ill effects."

And here is an index of many other articles about acai berry extract.

If you take it, let us know how it goes.  I am very curious.
