I'm trying to find studies that show the effect of "low" 25-0H vitamin D levels, what happens when supplementing with vitamin K2.
The opposite has been studies well enough, most search returns at vitamin D supplements with K2 or simply that both are needed.
Of the things I recommend, supplementing Vitamin D is definately a potent neurosteroid and having it dumped into your body in that way instead of via skin reacting to a light spectrum...
Similar to calcium and fluoride, I say avoid Vitamin D supplements. Plenty of people are in the oldest age spans and have had low levels of vitamin D for longer years then we have been alive...
I asked about studies regarding K2 and D3 and it auto wipes?
