Lovaza is like a special kind of fish oil medicine that can help people who have problems with their heart or with too much fat in their blood. You know how fish sometimes have little bits of oil in them? Well, Lovaza is made from those oils and it has something called omega-3 fatty acids in it. These omega-3 fatty acids are good for your body and can help your heart stay healthy. Lovaza comes in little capsules that you swallow like a big pill and it's important to only take it if a doctor says it's okay for you.
