So apparently there is no poisonous type of seaweed. Seaweed is a pretty good source of B12 (which apparently this lifestyle lacks slightly...). Plus it's supposed to have quite a lot of vitamins/minerals/antioxidants etc. which is good :)
Is dried seaweed raw? Like nori sheets? If not, could you eat seaweed raw? Or dehydrate it? Or is it really bad because similarly to fish it's been in the sea with all the oil spills and pollution and stuff? Is it too salty?
Just trying to find some vegan sources of B12 that aren't fortified/ from yeast/ in the form of a supplement or tablet!!
