KonaRed is briefly mentioned in the article, but still worth a read. I know KonaRed does the powdered form, but isn't the cascara syrup a form of the coffee fruit antioxidant extract that is also mentioned in the article?
I usually buy online directly from KonaRed (over $100 to save on shipping). I stopped by two Safeway locations in MD to stock up on my favorites and I could not find any KonaRed. The two locations were Canton and Arundel Mills. I take it as a good sign they must have been sold out.
