Omega-3 fatty acid products commonly known as fish oil supplements containing EPA and DHA are essential in ensuring our body is healthy. These polyunsaturated fatty acids are important in maintaining a healthy heart, and brain and also, have anti-inflammatory properties. However, there are issues when it comes to the suitable dosage and choosing the right quality of supplements.

Why and How Should You Take Fish Oil?

Fish oil is good for your body. It helps your heart, eyes, and brain work better. One of the key benefits of fish oil is its ability to fight inflammation, which is why many people incorporate it into their daily routine.

Doctors often tell folks to eat more fish or take fish oil pills. This is because fish oil has omega-3 fats that our bodies need but can't make on their own.

To get the most out of fish oil:

  • Eat fatty fish like salmon twice a week
  • Or take fish oil pills daily
  • Make other healthy choices too, like moving more and eating less junk food
  • Talk to your doctor about the right amount for you

Some people with very high-fat levels in their blood may need special fish oil medicine from a doctor. This stronger stuff can help lower those fat levels.

EPA and DHA are the long chain of Omega-3 fatty acids and are easily available in fatty fishes like salmon mackerel and sardine. These fatty acids are essential for the proper functioning of cells in the heart and brain throughout the body’s functions. EPA assists in decreasing the inflammation in the body and enhancing the health of the heart and DHA is important in the growth and functioning of the brain and eyes.

According to Toni Abelseth, Psychiatric Mental Health Nurse Practitioner and owner of Midwest Psychiatric Care:

Researchers believe that omega-3 fatty acids, especially DHA, are crucial for brain health because they help maintain cell membranes in the brain. Studies suggest that lower DHA levels are linked to Alzheimer's disease and increased protein deposits in the brain. Conversely, higher DHA levels seem to protect brain volume and cognitive function in healthy older adults. These neuroprotective properties are the main reason why I recommend omega-3 supplements to most of my patients, although some drug-drug interactions do need to be considered.

Recommended Fish Oil Dosage Guidelines

For general health maintenance, health authorities recommend a daily intake of 250-500 mg of combined EPA and DHA. For specific conditions, such as heart disease or high triglycerides, higher doses may be necessary. The American Heart Association suggests that people with coronary heart disease consume about 1,000 mg of EPA and DHA daily, preferably from oily fish. For those with high triglycerides, 2,000-4,000 mg of EPA and DHA per day, under a physician's care, may be beneficial.

Dosage Recommendations for Different Populations

  • Children: Omega-3 is vital in the growth and development of both children and adults. Health authorities set the daily allowance by age and state of health, nevertheless, children should intake between 50-100 mg of DHA daily.
  • Pregnant and Nursing Women: Omega-3s are important in the development of the fetal and infant’s brain in consideration of sufficient amounts of this nutrient. It is recommended that pregnant and nursing women should be taking at least 200-300 mg of DHA daily.

Health Benefits of Fish Oil

  • Heart Health: Omega-3 fatty acids decrease triglycerides, ease hypertension, decrease the chance of cardiovascular disease, and enhance total heart health.
  • Brain Function: DHA is part of the cerebrum and retina; it plays an important structural role. Sufficient intake enhances brain health, facilitates learning and memory, and could help in preventing the onset of Alzheimer’s disease.
  • Mood Regulation: More specifically, EPA belongs to omega-3s, an evident tool in regulating the signs of depression and anxiety.
  • Inflammation: EPA and DHA are important nutrients that can help relieve conditions such as arthritis or any inflammatory-related diseases.

Risks and Side Effects

While fish oil supplements offer numerous health benefits, excessive intake can lead to potential side effects. These may include:

  • High Blood Sugar: Large doses of Omega-3s can affect glucose metabolism.
  • Bleeding: High doses may increase the risk of bleeding, especially in individuals on blood-thinning medications.
  • Low Blood Pressure: Fish oil can lower blood pressure, which might be problematic for people with already low blood pressure.
  • Gastrointestinal Issues: Some people may experience nausea, diarrhea, or indigestion.
