High levels of fats can accumulate in the body and form triglycerides in the blood. Research has shown that omega-3 fatty acids can successfully reduce triglyceride levels in the body. They can also improve high-density lipoprotein HDL in the body.

In addition, a woman may experience a loss of DHA from the brain tissues due to childbearing. Taking fish oil supplements has significantly fulfilled the loss. Fish oil has also been used more recently as a potential treatment for autism.
