THE object of this paper is to record a continuation of experiments in which the existence is demonstrated of a "balance" between the vitamin B complex on the one hand and vitamins A and D of cod-liver oil on the other. Only two previous communications bearing directly on this subject have appeared in the literature, so far as we are aware. In the first place, Hopkins [1923] mentioned that he h...

Hypervitaminosis E in the chick.

BONE lesions have been described in animals given large doses of vitamin A. The bones are reduced in thickness and fractures are frequent (Moore, 1957). Much of this work has been done on the rat (Moore and Wang, 1945; Wolbach, 1947; Thompson and Pitt, 1960), but lesions have been described in other species including guinea-pigs (Wolbach, 1947), calves (Grey, Nielsen, Rousseau, Calhoun and Eato...

Patients and clinicians considering supplementation above currently recommended levels should be made aware of the possible toxicities of treatment with vitamin D, and baseline calcium and parathyroid hormone and vi...
