Reply To: Hi If I´m taking 50,000 IU D3 once a week, but I´m not taking any supplemental cofactors (ie Magnesium, Zinc, Vitamin K, Boron, Vitamin A) what is the effective amount of Vitamin D3 that I´m getting ? Thanks very much
Thanks so much for your replies — I really appreciate them. If you don´t mind, I have another question:
With regard to the studies that showed large decreases in cancer incidences as being associated with higher Vitamin D3 levels, did these studies a)either measure the levels of Vitamin D3 co-factors in the subjects, b)assume that the subjects were getting adequate levels of Vitamin D3 co-factors, or c)not take the levels of Vitamin D3 co-factors into account at all ?
i.e Is the decreased cancer incidence as a result of an increased Vitamin D3 level irrespective of the levels of the Vitamin D3 co-factors ?
Thanks so much for your attention to my questions.
