Cod is super high in Vitamin D, and considered by many historians the secret food that contributed to Vikings success.

Cod is super high in Vitamin A too and I would be worried about your liver.

According to USDA, Atlantic Cod has no vitamin A. What is your source?

Sorry, maybe it was a misunderstanding, especially since the Vikings were mentioned on the thread.

Pretty sure cod liver oil has vitamin A. Used to be a treatment for measles and rickets and others because of its vitamin A contents.
