Answer:
A number of studies have shown that supplemental calcium is linked to both heart attack and kidney stones in some people. For this reason, women are encouraged to get their calcium from food and dairy products and to only take supplemental calcium when advised by their physician for treatment of certain conditions.
Adequate vitamin D is also essential for good health but there are no links to heart disease from vitamin D supplements. Vitamin D levels can be measured in the blood and supplements should be taken only if these measurements are low.
