I don't know if you have seen all the hype about the acai berry or not but it is supposed to have some of the best anti-oxidant properties of any berry that can be eaten. It is said to have approximately 10 times the amount of anti-oxidants that grapes or other common fruits have. It also has anti-aging properties and people who have used the product have stated they have seen their skin look more supple and younger looking in less than 30 days!
I have not tried this personaly but would like to hear from anyone who has and hear their results.
