What happens if I take 5000iu vitamin D daily but don't get enough vitamin K2, will the vitamin D cause me problems or is it that I'll just be low in vitamin K. I know vitamin K2 is a cofactor for vitamin D.
The below is taken from http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/……..
There are two main types of vitamin K.
Vitamin K1, which comes from leafy green vegetables like kale, chard and spinach.
Vitamin K2, which comes from meats (organ meats in particular, such as liver), eggs, insects and hard cheeses. This type of vitamin K2 is called MK-4. There is also a different kind of vitamin K2, called MK-7, which comes from natto.
Vitamin K can also be taken as a supplement, either as K1 or K2, and the K2 can be either MK-4 or MK-7.
Research is still trying to sort it all out, but research is showing that you likely need both vitamin K1 and K2.
