The product "Selenium from Yeast" is Elemental Selenium and Selenomethionine in unknown ratios. The problem with this is that high dosages can deplete your methionine since most Selenium needs to bind to it.
I completely switched to SeMC and therefore had no Elemental intake in the last week or so, my best guess is that is why that one item changed.
Usually I watch this item:
SELENIUM | Deficiency causes hair loss, cancer, neuritis (nerves), bleeding, toxicity, whiteness of hair, mineral.
My intake of SeMC has dropped this from 104 to 54 (lower=better), in short where 800mcg of Selenium from yeast could not supply enough the 400mcg of SeMC supply more than enough. Yet the form essential for T3 conversion has moved up from 68 to 107...
