@gen55 Have your Vit D levels checked for sure, but what works for me is 125 mcg (5,000 IU) of D with 90 mcg K2.

There are varying strengths you can buy. On this, my numbers are good so far.

Important to note that Vitamin D is a fat-soluble vitamin, so taking it with a healthy fat like nuts or avocado enhances its absorption.
