I've had motion sickness and eye sensitivity for 2 yrs before recently supplementing with selenium.(but i don't do it everyday - as and when according to 'instinct!' mostly once or twice a week)
Yet was a fan of peanut butter back then - but still have a handful of brazils a day.
While not supplementing heavily and cutting out completely peanut butter for months - i'm able to travel on some days in a car now without too much nausea. Just not drive it!
I've read of studies with selenium binding mercury but thought in that state it became un-bioavailable. If in that state it DOES cross the BB barrier...jeeeesh. I wonder if that's why i can become very foggy-headed. I must admit on those days i tend to not have good walking balance and so therefore don't travel at all. Only travelling on clear-headed days.
Still- doesn't explain the car nausea and eye sensitivity while not supplementing - are you sure the food forms of selenium don't also have this effect?
My selenium is low and it's involved in so many body processes....i've been aware of needing to raise it - looks like i need to refocus on mercury removal asap.
What effect does mercury removal have on adrenal insufficiency? I can't cope with 'stress' as it is - aware i should avoid anaethetic during removal - i've found an excellent holistic dentist nearby.
Sorry for all the Q's! I'm abit skatter-brained today!
