This is the Iodine (Iodide) I switched over to from the BodyBio Iodine, which I'd taken for years. I've experienced start-up symptoms, and now more shifts than I did with the BodyBio.

And this is the Selenium (Selenite) that many people on the B12 Deficiency Site use to good effect. Nutricology and Allergy Research are the SAME company! This supplement can be found at iHerb, among other online stores.

There are several things that may have caused or contributed to this big shift for me. 1) Not long before I changed to the Genestra Iodine, I learned to take my minerals on an empty stomach AND without citric acid or Vit C before bed and first thing in the morning--although I later realized I had to take the iodine only in the morning because at night it caused insomnia. 2) In January-February of 2021, refeeding symptoms led me to take a higher dose of the Selenium than the 200mcg Greg recommends we titrated up to. I went slowly, observing symptoms, and reached just below 300mcg when the symptoms resolved.
I have held to that dose of selenium and will continue until I finish titrating up on the iodine in another few weeks. Once stabilized, I'll pause for about 4-6 weeks and redo my Thyroid numbers - TSH, Total T3 and Total T4; at that time I will also do a Hair Minerals Test put out by Doctor's Data as Greg likes to look at both to assess levels of the minerals and thyroid function at the same time.
I have never focused on Thyroid much, given my TSH was always in range, but looking back, I see that as far back as 2014, I was below range for T3 and have been all the years since. This may speak to why my start-up reactions are so noticeable...! A long time deficiency....
I might try and get these, or failing that get ones without any magnesium. Gonna go off the I/Se/Mo for a while and start it back up while titrating each individually... I didn't have to do much titration and took them all at the same time, maybe this is telling me something.
Thanks!
