Omega-3s 101

Odds are you've heard about omega-3 fatty acids. And for good reason! From brain development to heart health, they've been found to have many different health benefits. Read on to get a quick breakdown of the basics.


What are omega-3s?

Omega-3 fatty acids are essential fats. While they have many functions in our body and are important for good health, our bodies cannot produce them so we have to get them through our diet.


The three key types of omega-3 fats are:

  1. ALA (alpha-linolenic acid): Found in certain high-fat plant foods, especially flax seeds, chia seeds, and walnuts.
  2. EPA (eicosapentaenoic acid): Found in fatty fish, seafood, fish oil and algal oil.
  3. DHA (docosahexaenoic acid): Found in fatty fish, seafood, fish oils, and algal oil.


Keep in mind, while ALA is an omega-3, it needs to be converted into the longer-chain EPA or DHA omega-3 fatty acids to provide any of the related health benefits. Unfortunately, the human body isn't great at converting ALA. Studies show that we only convert ALA into EPA and DHA at a rate of about 5%1-2. So, many people choose to supplement their diet with EPA and DHA from fish or algal oil.


Why are omega-3s so important?

Omega-3 fatty acids have been studied thoroughly over the years. Research suggests that they can positively impact many aspects of our physical and mental health, including:

  • Support the maintenance of good health
  • Support and maintain cardiovascular health
  • Reduce serum triglycerides
  • Reduce the pain in rheumatoid arthritis in adults when consumed in conjunction with conventional therapy
  • Support the development of the brain, eyes and nerves in children up to 12 years of age


How can I get more omega-3s?

If you don't eat fatty fish regularly (or are a vegetarian or vegan!) you may want to consider taking an omega-3 supplement with EPA and DHA.


Omega-3 supplements are typically made from fish and algal oils. Be aware though that their quality and potency can vary widely. Look for supplements that have a Natural Product Number (NPN). The NPN ensures that the product has met the standards for quality, safety and efficacy set by Health Canada for Natural Health Products.
