Is Fish Oil a Safe Source Omega 3s

2013 was a bad year for fish oil. Claims were crushed that the long-chain omega 3s in fish oil—EPA/DHA—would stop the progression of heart disease. Then, DHA was associated with increased risk of prostate cancer and “monumentally” failed to treat macular degeneration. This over-the-top rhetoric sounded a little suspicious, and, indeed, the paper was retracted because the author sells some rival supplement he failed to disclose, but he does have a point.
