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
When they do studies they are not taking into account the co-factors. They only problem with that is if a study is done and they say that Vitamin D had no affect, then is it the D or is it because they were missing a co-factor that gave the results a poor outcome?
On the VDC page they do not list calcium as a “co-factor”. If you do not ingest any calcium then one of Vitamin D’s jobs is to absorb the calcium from your intestines. So it is pretty important to have both of them.
No, it is not better to describe Vitamin D as the co factor. There are receptor sites all over the human body for Vitamin D. It also turns “genes on and off” (regulates). So it has many, many important jobs!
