Non-Prescription Omega-3s and Your Health

Omega-3 supplements can help make up for a lack of omega-3 fatty acids in your diet.

But when it comes to preventing or treating disease, many studies have not found much benefit in taking low daily doses of omega-3 supplements.

However, if you have heart disease, the American Heart Association recommends higher amounts of omega-3s that may be hard to get from diet alone. So, ask your doctor if supplements or prescriptions are right for you.

Very high triglycerides are also linked to pancreatitis.

Two types of prescription-strength omega-3 fatty acids are available:

  • Epanova (omega-3-carboxylic acids). This contains a combination of EPA and DHA.
  • Lovaza (omega-3-acid ethyl esters). This contains a combination of EPA and DHA.
  • Vascepa (icosapent ethyl). This contains EPA only.

Omega-3 fatty acid supplements come in many different doses and types. Each supplement can contain different ingredients, depending on the manufacturer's standards.

Non-prescription omega-3 fatty acid supplements may cause mild side effects, such as:
