I give my dog (who has cancer) a product called blue green alge from Klammath Lake. It's a pill & I was wondering if that was the same thing you're talking about. My vet says that its a wonderful product & the guy at the health food store says it's a good antioxidant. Are you talkig about the seeweed stuff you get at the HFS like Komubu (sp?). Thanks for some more info Meryl
