Iodine Confusion

Hello! I've been spending the last few days in the iodine supplementation forum. My Mom has had thyroid issues (ended up with a thyroidectomy a few years ago) and I want to support and keep my thyroid in good working order. I have recently noticed more hair loss than normal in the shower and on and off edema in my ankles, which are two signs of hypothyroidism, I believe. In addition, it seems difficult to lose weight. I have been healthy otherwise and generally feel good, just groggy in the morning since I quit coffee.

Anyway, just this afternoon, I ordered Iodoral off Amazon, thinking I would take one of those each day in an effort to ensure my thyroid is getting enough iodine/iodide.

So, was ordering Iodoral a mistake? After reading some of the posts on this forum, it would seem that might be the case.

Do you know what else I should take along with the Iodoral, or in place of it? I had read on the Iodine supplementation forum about making sure I get companion nutrients like Vitamin C (3,000 mg or more), Magnesium Oxide (300-600 mg), Selenium (200 mcg), Niacin (500 MG two times per day), and B2 (200 mg)...

Anyway, what am I in for, in your opinion, if I take Iodoral?

Finally, I came here because I have shown up as slightly acidic with the PH test strips over at least the last several years. What is your advice for getting my system to a better PH balance?

Thanks in advance for your insight!
