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
No, it’s not the correct way to look at the situation.
If you do not take any co-factors, you will still absorb whatever amount of Vitamin D you take unless perhaps you have intestinal problems. Then sometimes people have trouble absorbing the Vitamin D in pill or capsule form and need oral sprays. After that, for “example”,if there is absolutely no calcium in your diet it is Vitamin D that helps calcium absorb from your intestines and then the calcium can be sent to your bones. If there is no calcium none can be sent. If there is not enough Vitamin D, then you will not absorb the calcium like you should and again then none will reach your bones.
So really we are hoping that your diet contains the nutrients so you do not have to take co-factors in supplement form.
The one mineral that can be harder to get in your diet is magnesium. Just taking magnesium alone can solve a lot of health issues. If there is not enough in your diet, then sometimes taking Vitamin D will give you for example a headache. It is not the Vitamin D that is the problem, it is the lack of magnesium. Vitamin K also directs calcium to your bones and away from soft tissues where you do not want it. So if you take Vitamin D, which then absorbs calcium and there is no Vitamin K, your body will not know what to do with the calcium and it could go to the wrong place.
Now if someone said but I cannot afford to buy any supplements except for the Vitamin D, I would tell them to buy the Vitamin D and take it. Better with it, then without it!
I hope this helps and if you have further questions, just ask!
