COULD YOUR MULTIVITAMIN GIVE YOU BREAST CANCER?  Well, at first glance this study might suggest this.  The increased risk is small (19%) compared to other things, but is still real.  Probably the biggest concern I have with this study and most MVM studies is that there is a huge difference between MVMs on the market.  At one end you have the “one a day” types that are by far the most popular.  These are generally very low quality (for a variety of reasons too lengthy to go into here).

Of concern is that many contain artificial colors (really–does anyone CARE what darn color your MVM is anyway????) such as FD&C dyes.  These are coal tar based and are known to be carcinogens.  This would obviously be of concern in a study looking at cancer.  Then there’s always the folic acid concern that folic acid may promote cell growth in a cancer already present.

Bottom line?  Most of the research supports the use of a MVM for long term health, but it is NOT a patch on a poor lifestyle.  Rather, it is used in conjunction with a healthy lifestyle.
