icon23 273 Posted January 16, 2013 I am not sure about the Biotin, but the biotin I have is only 1000 mcg. The guidelines I have been given for B12 is only 500 mcg orally daily or a 1000 mcg injection (from your doctor) monthly. Share this post Link to post Share on other sites

O.T.R. sleever 3,386 Posted January 30, 2013 B12 is a Water soluble Vitamin. It's nearly impossible to get too much. The body will simply flush what it can't use. Check out energy supplements. Many of them contain 1000% or more of the daily allowance of B12. Share this post Link to post Share on other sites
