(Answer: None of the above, Omega-3 fatty acids can be “found” in fish BUT, they actually originate in micro-algae...the natural source!!)
Fish obtain all of their Omega-3 and Omega-6 fatty acids from the food that they eat like smaller fish and of course Algae.
Algae synthesise the Omega-3 oils, then tiny crustaceans called krill eat the algae and then fish eat the krill; concentrating the DHA in a nice, convenient, fishy package (assuming that we’re not concerned by the build up of heavy metals like mercury and other pollutants floating around in the world’s oceans!)
Traditionally fish oil or cod liver oil supplements have been the go-to source of Omega-3 around the world. Even vegetarians and vegans would often have to compromise on their values and take these supplements to meet their Omega-3 requirements.
Luckily, it is possible to side-step this entire process and obtain healthy vegan DHA straight from the algae, which can be grown in tanks and harvested once they’ve created a stockpile of healthy oil.
We strongly believe that algae are the best possible source of Omega-3 fatty acids.
The DHA found in algae is clean, easy to digest and very bioavailable. It’s nature's original source of Omega-3!
It’s also bundled with a number of other, beneficial compounds like the phytosterol compounds campesterol, and sitosterol, which have been shown to reduce serum cholesterol levels (52).
Summary: Algae-based supplements are also environmentally friendly, ethical and 100% sustainable, which means that you don’t have to worry about them having a devastating environmental impact to our planet unlike fish oils.
