Back in the day, like ten years ago or so it was very trendy for health gurus to promote high doses of fish oil supplementation (minimum 3g daily of combined EPA+DHA, ideally way more). You can still find posts from angry users in forums complaining about loss of libido, hypothyroidism and erectile dysfunction. I would stay away from it, but it might be worth it for vegetarians, pregnant and lactating women. Or if you eat the average (crap) western diet.
