Q. Someone wrote you to complain that fish oil makes him vomit. I take 1200 mg of fish oil daily. My young, savvy doctor told me to keep the capsules in the freezer to prevent aftertaste. That might help prevent his nausea.
A. Although we could find no scientific support for freezing fish oil to reduce the objectionable aftertaste, many people have found this tactic helpful. We don’t know whether it would work for someone who cannot tolerate fish oil.
