I take one 50,000 pill of D2 once weekly, still here, I have been reading that taking it with vitamin K helps remove calcium from veins and arteries and transfers it to the bones where it belongs.
Vitamin k helps to reduce excess vitamin d.
I think people take too much vitamin d. It would cause problems, so supplement makers sell vitamin d overdose capsules with the antidote in the same capsule.
Same result taking Boron.
