I am reading a lot of conflicting evidence on the internet about Calcium intake. At the moment i am not getting a lot of calcium in my diet, so i was thinking of getting a supplement or eating more calcium rich foods.

But i came across these videos

KGNU Calcium and Heart Disease 2010.mp4 - YouTube

The Calcium Lie - What Your Doctor Doesn't Know Could Kill - YouTube

What do you guys think? How much Calcium do we really need?
