I just just found this interesting article:
"Elderly men and women who consumed higher levels of calcium and vitamin D are significantly more likely to have greater volumes of brain lesions, regions of damage that can increase risk of cognitive impairment, dementia, depression and stroke. "
"In addition to its well-known function in bone health, calcium is important to the functioning of nerve and muscle cells. But when too much calcium is taken up into blood vessel walls, the calcium becomes incorporated into bone-like deposits that can lead to loss of elasticity and narrowing of the blood vessels. Vitamin D helps regulate calcium retention and activity, which may further enhance this arterial calcification. If blood vessels in the brain are affected, damage could lead to brain lesions.
At this point," says Dr. Payne, "we do not know if high calcium and vitamin D intake are involved with the causation of brain lesions, but the study provides support to the growing number of researchers who are concerned about the effects of too much calcium, particularly among older adults, given the current emphasis on promoting high intakes of calcium and vitamin D."

Same Dr Payne has written the book "The Health Benefits of Vitamin K2"
Here an extract of one interview to Dr Pyane:
SWANSON: To me the most fascinating part of your book was the discussion on what you call "the calcium paradox." Please explain this to our readers.
DR. PAYNE: The "calcium paradox" refers to the fact that while we need calcium, too much or too much in the wrong manner can actually be harmful. You see, even though a person may be getting enough calcium in the diet, the body may be unable to retain it or deposit it into the bones; instead, it will accumulate elsewhere, typically in soft tissues such as veins and arteries, which is counterproductive to cardiovascular health. The whole thing can really be summed up by saying that unless we are able to get calcium to the right places, like the bones, we could actually damage our health by accumulating too much in other places, like the walls of our arteries.
SWANSON: To cut right to the heart of the matter, your book focuses on the apparent fact that Vitamin K2, specifically Menaquinone-7, is integral in getting calcium to the right place-into the bones and out of the arterial walls.
DR. PAYNE: That's exactly right. Menaquinone-7 accomplishes this goal better than any other Vitamin K compound.
SWANSON: I've read your book twice, and I must say that your documentation of the scientific research supporting the "calcium paradox" is quite impressive. Let's get back to that. If calcium doesn't get to the bones due to a lack of Vitamin K, what happens?
DR. PAYNE: What happens is that it accumulates in the blood and eventually deposits itself along the walls of the arteries and blood vessels. There's overwhelming evidence, documented in my book, which shows that when Vitamin K2 is lacking, calcium does not get taken up optimally into the bones. Plus, continuing research is telling us that by increasing our intake of K2, we can help this process along and put calcium in the right place-in the bones.

If you are taking blood thinners you should ask your doctor before taking vitamin K,
