...unlike selenomethionine, SeMC doesn’t build up
in your tissues – a fact which resolves the curious finding
that you can predict a person’s cancer risk from the amount
of selenium in his or her diet or in the local soil and water,
but not from the amount of the mineral in his or her tissues.
In short, SeMC will do the anti-cancer and cell differentiation work we expect regardless of what else is in the system to interfere, that includes arsenic.
But T3 production might require the mineral in the actual tissue, so for now 50-200mcg of Selenium from Yeast and the rest in SeMC looks like a great solution.
But please keep up because if new info shows up next week all this might change :)
