Men consuming 2000 mg of dietary calcium per day 25% less likely to die over 10 years vs 1000 mg

The one-third of men consuming the most dietary calcium -- roughly 2000 mg per day -- were 25% less likely to die over the next 10 years compared to the one-third of men consuming the least dietary calcium -- roughly 1000 mg per day -- according to a study that followed 23,366 Swedish men, aged 45–79 years, who were NOT taking dietary supplements.
Two-thirds of dietary calcium was from milk and milk products
“The main sources of this nutrient in the diet were milk and milk products (68.5%),” the paper notes.
Comment: Calcium supplements do NOT reduce risk of death
Another study found that calcium supplements did NOT reduce the risk of death
Another paper analyzing data from 9 other studies found that calcium supplements did NOT reduce the death during the studies, but instead INCREASED the risk of death by 1%, although this was not statistically significant, that is, it could have been due to random chance.
At the very least this other paper suggest that calcium supplements do NOT provide any protection, and may actually INCREASE the risk of death.
The take-away message for me is to get your calcium from dietary sources and NOT from supplements.
