What are the types of Omega-3?
There are three major Omega-3 fatty acids in our diet: alpha-linolenic acid ALA, eicosapentaenoic acid EPA, and docosahexaenoic acid DHA.
- ALA is presently the plant version of Omega-3 found in foods such as flaxseed, soybean, and canola oils.
- DHA and EPA are present in fish, fish oils, and krill oils, but they are originally synthesized by microalgae. Marine animals accumulate Omega-3 in their tissues over time as they ingest phytoplankton that consumes microalgae.
What are their roles?
ALA, EPA and DHA are all present in our body, but EPA and DHA are particularly enriched in our brains and eyes. Apart from being key components of our cell membranes, Omega-3 fatty acids are also involved in supporting vision and heart health. Ongoing scientific studies continue to provide evidence for other health benefits of EPA and DHA.*
