I picked up some Frontier Powdered Kelp (not the granules) yesterday at Wild Oats and tried it for the first time. I have to say, it really seemed to be MUCH better than the Now brand. The Kelp at Wild Oats was labeled Norwegian as well... curious as all the online Frontier Kelp has stated Icelandic. Have you found different?
It was about twice the cost of Now granules, and I have about 3lbs left, so will have to work through it.
