The Vitamins of Cod Liver Oil
According to Professor Kestner, physiologist of Hamburg, in the Far North, under all meteorological conditions, the ultraviolet radiation is stronger than in central Europe. That explains in the main the unusually rapid development of plants in the short summer of the Far North and also the storage of vitamins. The sea plants store up the vitamin in relatively large quantities, owing to the highly potent radiation. These are eaten by small animals, and these in turn by other animals, and the cod preys on them all. Thus the liver of the cod becomes the reservoir in which all the fat-soluble vitamins of the masses of devoured sea plants are deposited.
