Studies strongly indicate that Omega-3 fatty acids from fish oil can lower blood pressure and triglyceride levels. Heart attack victims that are treated with Omega-3 fatty acids may have a lower risk of future heart attacks.
There are three different types of Omega-3 that come from different resources. Docosahexaenoic acid (DHA) and eicosapentaeonic acid (EPA) come from fish oils while alpha-linolenic acid (ALA) comes from plants and is converted to Omega-3 in the body.

The recommended dose for Omega-3 fatty acids can range from 1 gram of EPA and DHA for people with heart disease to 4 grams per day for people trying to lower triglycerides. Consulting a physician would be the best way to determine a person's ideal dosage.
