Eskimo-3 is not concentrated by chemical modification, but has the same mixture of fatty acids as in the fish. A natural fish oil cannot have a higher concentration of omega-3 fatty acids than Eskimo-3 - 38%. Eskimo 3 is not from the liver of the fish - it is fish body oil and is therefore purer than cod liver oils. Defrived from sardines, which is the best source of high quality fish oil. The sardines come originally from the Antarctic and are caught outside South America.
Eskimo-3 has retained its natural antioxidants during processing and contains added vitamin E, making it incredibly stable. Most fish oil products available today become rancid when exposed to air. Eskimo-3 remains fresh for longer without going rancid so it has no fishy smell or after taste. Eskimo-3 comes in the convenience of either capsules or liquid. The pleasant tasting liquid form is often preferred by children who are frequently resistant to swallowing capsules and tablets
