Fish oil supplements are very popular in the market because of its omega-3 fatty acid content. 

Omega-3s are polyunsaturated fatty acids that have a wide range of benefits.

They improve your skin health, decrease the risk of heart disease, reduce joint pain and discomfort, help clear mental fog, improve cognitive function, and strengthen immunity (1), (2). Omega-3s also reduce triglyceride levels in the blood. 

Omega-3s are mainly of three types: eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and alpha-linolenic acid (ALA) (3).

The former two are primarily found in fish oil while the latter is found in plant foods. However, ALA has to be converted into EPA and DHA  before the body can use it.

Therefore, people who can’t consume fish regularly can greatly benefit from taking fish oil supplements.

Dosage for Fish Oil Supplements

Fish oil is an excellent source of the main omega-3s: EPA and DHA which supports brain development and ensures good heart health (4). The typical Western diet is often low in omega-3s, therefore taking fish oil supplements can go a long way to boost your nutritional health.

The reference daily intake (RDI) of EPA and DHA, combined is 250-500 mg. When you are buying your fish oil supplement, make sure you read the labels and determine how much is being provided. Normally a 1000 mg of fish oil provides 300 mg of EPA and DHA.

Up to 3000 mg of fish oil is considered safe for adults and does not cause any side effects.

However, recommendations for EPA and DHA vary according to age and needs. Below mentioned are a few examples:

  • Omega-3 intake for infants up to the age of 1 year is 500 mg
  • For a 4-year-old, combined EPA and DHA  is around 100 mg.
  • For an 8-year-old, the need is 200 mg.
  • For people with coronary heart disease, 1000 mg of total EPA and DHA per day is recommended
  • For pregnant women, WHO recommends 300 mg of combined EPA and DHA per day, where DHA should be at least 200 mg.

Some fish oil also contains certain fat-soluble vitamins such as vitamin A and D which is essential for bone health, strengthens immunity, and helps improve eyesight.
