Here is a comparison.
Their are many that swear by his foods, I'm not one of them. The ingredient list is really no better than any other low end food which uses alot of fillers such as corn, wheat, and oat flour which serves as fillers and binding agents. Look at their list and then compare to NLS flakes which uses actual whole Antarctic krill and whole hearing instead of fish meal which utilizes all the left over parts from other industries rather than the whole fish. Compare and you'll see the differences.
