Question: I noticed that some ingredients in my multivitamin have no daily value established. A few concern me, specifically Boron (150 mcg per tablet), Nickel (5 mcg per tablet), and Tin (10 mcg per tablet). Should I be concerned about these ingredients?

Answer: It may seem surprising to see ingredients like boron, nickel and tin on a supplement label. However, boron and nickel are found in many foods, and tin is sometimes used as an inactive ingredient in tablets. The small amounts found in your multivitamin do not pose a concern -- at the same time it's not clear if they offer any significant benefit.
