Well I’m on 20,000 iu daily since blood work did show really low. Also B12 so had shots for three months and now on vit B compex....but not aware of taking k2?
A good many - mostly recent — studies show taking Vitamin D3 with Vitamin K2 helps to ensure the calcium transported by the Vitamin D is absorbed by your bones where it’s needed, rather than accumulating in deposits in your arteries (hardening of arteries) ...or causing kidney stones.
Do a search of ‘’vitimin d and k2’’.
BTW - B12 doesn’t survive well in stomach acid. May want to use sub-lingual B12.
