but shouldn't you always complement vitamin d intake with vitamin k? If I recall correctly (I am not sure!) then vitamin d without vitamin k can be harmful.

Vitamin K is found in vegetables, so you don't need to supplement it. I think the worry is that too much Vitamin D contributes to buildup in arteries over the long term, and K helps to clean it.

>Vitamin K is found in vegetables
"Vegetables" is a category that's about as useful in this context as "food".
If you mean taking more D than is needed, your are correct.
You can measure the D vitamin levels from blood serum.
Adequate level has increased over the years.
