The Centrum Research Group has spent years studying the changing vitamin and mineral needs of adults 50+. That's why the Centrum Silver formula is carefully balanced and adjusted to help meet those changing needs. Centrum Silver contains higher levels of vitamins E, B6 and B12, as well as calcium and chromium, when compared to Centrum, and it's iron-free. It's the reason why Centrum Silver is a complete multivitamin for people over 50. And, now Centrum Silver contains lycopene, one of the ingredients in tomatoes that may help reduce the risk of heart disease!
