Essential fatty acids
Krill oil provides long-chain omega-3 fatty acids (EPA & DHA) in the phospholipid form. Phospholipid-bound omega-3 fatty acids are dispersible in water, which is different than the omega-3s provided by fish oil.
This property makes krill omega-3s better absorbed in the intestine and more efficiently utilized by tissues. The phospholipid form also avoids the fishy burps often associated with fish oil. Krill are rich in the natural antioxidant astaxanthin that is recognized for health-promoting suppression of free radicals and helps maintain the shelf-life of krill oil by reducing oxidation.
The deep red color of each softgel is due to this astaxanthin content.
