Our Members Asked:
I noticed that some ingredients in my multivitamin have no daily value established, such as Boron (150 mcg per tablet), Nickel (5 mcg), and Tin (10 mcg). Should I be concerned about these?
Medically reviewed and edited by Tod Cooperman, M.D.
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. For more about boron, nickel, and tin see the full answer >>Also see ConsumerLab.com's Reviews of Boron Supplements and Multivitamin and Multimineral Supplements >>

December 14, 2014I never heard of TIN listed as an ingredient on the labels of any of the many supplements I take every day. But on a lighter note, I can't help thinking about the Tin Man in the Wizard of OZ, (clearly evidence of a severe tin overdose at some point). However, the Tin Man was the warmest-hearted character in that famed classic and ends up with a brand new heart at the end!
