Blood Pressure

• Fish oil contains omega-3 fatty acids. These acids have been beneficial in protecting blood vessels from plaque, thus reducing inflammation and preventing high blood pressure.
  
  

Rheumatoid Arthritis

• Fish oil contains EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid); these two omega-3 fatty acids have been shown to be particularly helpful in alleviating joint paint and morning stiffness for people suffering from rheumatoid arthritis.
  
  

Weight Loss

• According to the Mayo Clinic, there is some evidence that the fatty acids in fish oil can be beneficial in weight loss. Fatty acids help keep arteries clear, enabling the extra oxygen-rich blood needed by the heart, to sustain regular physical activity.
  
  

Other Uses

• Fish oil is used to treat a variety of health disorders by boosting immunity, lowering trigylcerides, slowing buildup of atherosclerotic plaque, and reducing inflammation. These health disorders include hypertrigylceridemia, atherosclerosis, macular degeneration, painful menstrual periods and cardiovascular disease prevention.
