This pilot study from 2019 suggests that consuming omega-3 fish oil supplements is a bad idea. They found that
33% of the fish oil products contained significant levels of aldehydes which are a potential oxidation product of omega-3 fish oils (basically the fish oils are rancid).
@reshiram I didn't click on the study, but I believe you. I'll note if I get any bad sushi indigestion farts.
