EPA & DHA in fish oil pills?

My doctor told me to take an omega fatty acid supplement daily. She said on the label to make sure the EPA + DHA = 2000 mg. Well, I've looked and looked at various brands' labels and none even come close to that. Could she have been wrong? I've seen bottles of 2000 mg fish oil, but the EPA+DHA only adds up to way under 2000 mg. What do you think?
