Jumbelina Brazil nuts only contain selenium if they've been grown in selenium rich soil, the packaging will say if they have, otherwise the only way to know how much selenium you are getting is to supplement.
If you can get Brazil nuts grown in selenium rich soil then 2-3 a day is enough.
Thank you- I didn't know that about the soil - interesting. I don't have the info on the soil where the nuts were grown but I like Brazil nuts and am happy to eat them most days so I'll take a chance on getting nutrients from food rather than taking more pills.
It's a nice small tablet with no unpleasant odour like a lot of them have.
Stay away from ThyroAid, it contains the wrong form of B12 (cyanocobalamin, it should be methylcobalamin), also iodine which we shouldn't take unless tested and found deficient, the wrong forms of magnesium and zinc (oxide) and contains soy (us Hypos should avoid soy unless fermented).
You're better off testing vitamins and minerals if not already done and supplement where necessary
Vit D
B12
Folate
Ferritin
A good multi mineral (not multi vitamin) that doesn't contain iron, calcium and iodine can be helpful.
