Unfortunately, the fish oil trend train is barreling down the tracks, fueled by misinformation. It is powerful, popular—and harmful. Do your best to stay out of its way. Instead of fish oil supplements, look for fish-free, plant-based, algae-derived omega supplements. Whenever you start to feel persuaded by the arguments in fish oil’s favor, remember: fish oil is the snake oil of today! Treat it warily. It will not fulfill its promises.
