Krill Oil as source for Omega 3’s
The EPA and DHA molecules in krill oil might be more easily absorbed by the body than those of fish oil. That’s because EPA and DHA in krill oil are bonded to phospholipids, and those in fish oil are bonded to triglycerides.[8, 9, 27] Phospholipids are more absorbable because they dissolve in water, whereas those in fish oil don’t. That means in order to get the most benefit from fish oil, it must be consumed with fatty foods; no such limitation applies to krill oil.[11, 14, 28]
Krill oil also naturally contains astaxanthin, which is a powerful antioxidant. Astaxanthin is the red pigment, a carotenoid, that gives some marine organisms their red color. Research studies for its health effects on the body are highly promising.[23, 24] Preliminary results indicate that astaxanthin reduces inflammation, reduces oxidative stress, protects cells, and promotes heart and brain health.[29, 30, 31] There are also very promising studies that indicate that it may also help prevent cancer and generally improve improves immune function.[32,33, 34] Astaxanthin has also been demonstrated to help with eye health, specifically macular degeneration.[35,36]
In krill oil, astaxanthin helps to keep omega-3s from breaking down and going rancid, and has been shown to generally reduce oxidative stress and inflammation.

Algal Omega 3
Algal oil contains significant amounts of DHA and small amounts of EPA. As a result, it’s a great option for vegetarians, vegans, and people allergic to seafood.
Although research on the specific health benefits of algal oil is limited, some studies show that the DHA in algal oil has anti-inflammatory properties and other benefits like fish and krill oil omega-3s. The DHA in algal oil has been found to be just as absorbable as that in fish, and algal oil is also free of the contaminants found in fish, especially those that are farmed. Algae used to source algal oil is grown in laboratory conditions, never actually touching sea water. If a high-quality growing and manufacturing facility is used, algal oil produced in this way has less exposure to potential contaminants. EPA and DHA in algal oil are in triglyceride form and thus well-absorbed by the body.
