I know it's not something that will ever taste like strawberry jam, but it's nasty. I've taken 3 tablespoons so far and haven't gotten sick, so I don't really think it's rancid, but I don't know for sure.
So you shouldn't be able to taste the oil for the rest of the day? I've tried a couple flax seed oil brands where this happened to me, they both had very strong flavors. I guess its possible they were both rancid? Not sure if I want to try another brand or not...
