Thanks for the response, the only RX he takes is a statin for the cholesterol(pretty sure it's atorvastatin) and OTC the occasional ibubrofen when he is feeling sore, but sometimes it is a high dose 800mg, or he is on it for a week at a time, and he always takes a multivitamin and selenium.
And yes the most recent labs were for free T3 and T4, didn't feel it was necessary to make the distinction, not sure how knowledgeable the people who replied would be lol (glad they are). I know his TSH was in the reference range of the lab that administered it, can't remember exact #, but as you say that might be sub optimal even if it was in range.
And I know salt in and of itself isn't bad for cardiovascular health, my mother just has an old school way of thinking haha. Plus as I'm sure you know the iodine you get from certain types of salt is essential for thyroid function. By the way my mom has been on female HRT since menopause and seems to be fine physically and emotionally (although I do worry about the increased risk of stroke) and I doubt she is iodine deficient.
He had a prostate exam (I think) last year, and he told me it was fine. But I will try and get him to get the rest of those markers checked out, and getting the labs will not be a problem. Thanks
