How did Eskimos and Inuits living in harsh and snowy conditions not die of scurvy before modern food transportation?

Scurvy is the lack of vitamin C which the human body cannot synthesize.

Vitamin C is available in organ meats and in whale skin + blubber, which the Inuits call "muktuk". These were their sources for vitamin C during times when berries or other vegetation sources of C were not available.
