As we all know, fish oil has become very popular since the 2000s. It's in the news constantly and people are encouraged if they don't take fish oil, to make sure they eat several servings of cold-water fish per week. I've read testimonials online of both people who have bad effects from taking fish oil and people who say all their symptoms come back if they stop taking it. Some insist it has made their hair, skin or nails healthy. Did you take fish oil or eat a lot of cold-water fish in the 2000s and if so, what were your results?
