Do brazil nuts lower thyroid?

I was recently told I have a slightly overactive thyroid, and someone suggested that eating Brazil nuts could be beneficial. My question is, do Brazil nuts lower thyroid levels, or do they only support general function?

Brazil nuts don't cure or lower high thyroid levels on their own. As someone who has managed thyroid issues for years, I highly suggest getting regular blood tests and sticking to your doctor's prescribed dosage.

I bought a packet hoping they would magically fix my sluggish thyroid and wake me up, but they don't lower thyroid levels by themselves. They just provide selenium which helps with normal function. Still sleepy, though!

They only support the thyroid due to the selenium they contain, they don't lower it. You can eat one nut a day for general health, but please consult a doctor for proper thyroid medicine if your reports are abnormal.

I ate too many Brazil nuts trying to self-treat my thyroid and got selenium toxicity, which made my hair fall out. Please do not self-prescribe natural remedies and see a proper doctor for thyroid issues.

No, they don't lower thyroid function. They actually support T4 to T3 conversion because of the selenium. Just don't go overboard; one nut daily is the maximum you need alongside your regular workout routine.
