Benefits of – Omega 3 Fish Oil

Omega 3 Fish oil is available as a dietary supplement that is obtained from the tissues of certain kinds of oily fish. The most vital elements of fish oils are docosahexaenoic acid (DHA), omega-3 fatty acids, and eicosapentaenoic acid (EPA). These are considered to have various health benefits like enhancing mood & immunity and reducing oxidative damage in the body.

There are three categories of omega-3 fatty acid that include:

  • Omega fatty acid- docosahexaenoic acid (DHA)
  • Omega fatty acid- alpha-linolenic acid (ALA)
  • Omega fatty acid- eicosapentaenoic acid (EPA)

✅ Fish Oil Omega-3 consists of both docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). Omega-3 fatty acids are vital nutrients that are important in managing and preventing heart disease.

✅ Studies show omega-3 fatty acids can help to:

  • Slows the development of plaque in arteries
  • Reduces the chance of abnormal heart rhythm
  • Lowers blood pressure
  • Reduces triglycerides
  • Lessens the possibility of abrupt cardiac death in people with heart disease

Fish Oil Omega-3 has benefits for heart disease.

Studies have suggested the effects of taking omega-3 supplements for heart disease. There was a modest reduction in mortality in people with established coronary heart disease, as well as those with heart failure.

Thus, further research is needed in this regard.
