The Pros and Cons of Taking a Fish Oil Supplement

May 4, 2017

A fish oil supplement is often recommended to people who don’t eat much fish in their daily diet, but still want the heart and vascular benefits of omega-3s. It might seem like an easy solution to just add an extra pill to your vitamin routine, but you might not always be getting the benefits you expected. While you should always speak to your doctor before adding a supplement to your diet, we’ve compiled a quick list of pros and cons to help you decide if a fish oil supplement is the right choice for you.
