As illimanx said - i've read studies of the HUGE affinity mercury has for selenium.
I had not come to the conclusion about the BB barrier though and will look into those studies deeper to see if that was also discovered...i could have easily over-looked this correlation as i was soaking up so much at the time.
I feel good on selenium when i DO take it - but jeeesh....with so much toxicity already - i'm kinda fearful of opening up that BB barrier. Hence why i've avoided Alpha-lipoic-acid (N.B..NOT alpha linoleic acid) as i knew that helps mercury cross the BB barrier.
Altho' maybe once that barrier has been breached (as im already guilty of, without knowing) it might do no more harm!!! lol
I desperately need to up my selenium. Am very torn what to do.
