Yes, K2 and probably also magnesium (preferably chelated). But look it up or even better, consult with a wellness MD. They can tell you exactly what you need.
It is my understanding that you should have your blood level of vitamin D checked annually, in order to establish how much D you should take orally. It is a simple and inexpensive test. [Why is it not a standard test, when Vitamin D is so critically important to our health? Maybe because modern medicine is not interested in making you truly healthier, because healthy people are not profitable.]
All the best to you and yours.
Thank you for the information and advice :)
