New research is confirming once more what many have known for years — calcium supplements, which are biologically foreign to the body (as opposed to food sources), can actually spike your risk of heart attack by a very significant amount. Labeled by the researchers as “not safe or effective,” the latest study reached the startling conclusion after examining 24,000 middle-aged and elderly participants for 11 years. The increased heart attack risk when taking the calcium supplement is represented by a leap from 1 in 700 affected individuals to about 1 in 300.
