Video Description:

The Vikings suffered many hardships living in the north of Europe: long, cold winters and importantly a lack of sunlight. Luckily, they had cod. When making a video about vitamins I thought the story would mainly be about supplement pills, whether we should or shouldn't take them and how they're made. But what I found out is vitamins have a remarkable story that affects many more aspects of our lives. For example the Vikings needed a source of vitamin D to last the dark winter months and for their children to develop strong, healthy bones, avoiding rickets.

    Quite interesting. I remember taking the cod liver oil concentrate as a child. It was administered by dropper and all 3 of us loved it. I was the one who figured out how to climb up to the cupboard where it was kept and like a mother bird, giving some, drop by drop, to my brothers, not forgetting myself. Haven't thought about that in years.
