Long-chain omega-3s
There are two main types of omega-3s: shorter chain and long chain omega-3s (see the figure below). Current scientific evidence highlights the importance of long chain omega-3s for the development of the brain and eyes, for heart health, as well as managing good health.
What is EPA?
Eicosapentanoic acid (EPA) is a long chain omega-3 predominantly found in oily fish and is beneficial for reducing inflammation and helps to manage and reduce the risk of heart disease.
What is DHA?
Docosahexaenoic acid (DHA) is considered the most beneficial long chain omega-3. It is especially important for brain growth and visual development of the unborn baby and studies have shown it helps to manage and reduce the risk of heart disease. DHA is predominantly found in oily fish and algal oil.
What is DPA?
Docosapentaenoic acid (DPA) is the predominant long chain omega-3 found in lean red meat. DPA has been less well studied yet the evidence available suggests DPA has similar heart health benefits to EPA and DHA.
What is ALA?
Alpha-linolenic acid (ALA) is a ’shorter chain omega-3′, which is important for health, yet is poorly converted in the body to the more beneficial long chain omega-3s. Food sources of ALA include canola and linseed (or flaxseed) oils, soybeans and green vegetables.
