Quote from Chapter Ten of BLUE GENES, by Paul Meier, M.D., et. al., (Tyndale Publishers, 2005), pages 168-169:

"It showed that Swedish women, ages 45 to 70, who regularly took a normal vitamin pill of any kind, had a 33% reduced risk of having a first heart attack, and men in that same age range had a 22% lower risk. Of course, part of this result could be because people who take vitamins are more responsible to do other healthy things in their lives.... The researchers themselves considered these possibilities, and factored in such elements as smoking, exercise, and diet, and came to the conclusion that the overall cardiac benefit of the vitamins alone was about a 20 percent reduction."
