Fish oil supplements have long been promoted as an easy addition to the diet for individuals looking to protect their heart health, ease inflammation, improve mental health and even to increase longevity. They are one of the most commonly consumed dietary supplements, taken for their rich levels of omega-3 fatty acids and widely believed health benefits. Americans are estimated to spend more than $1 billion a year on over-the-counter fish oil products and companies nationwide are incorporating omega-3 fatty acids into dairy products, cereal, juice, and hundreds of other food items.
