I would agree with your thinking. You are playing with very very low doses....1/2 to 3/4 mg. Dr Brownstein usually doesn't see people have changes unless he gets them to at least 12.5mg and often higher.
Seaweed is great if it is tested to be clean! IF.
Gosh, it is 50% mineral content by weight....awesome for minerals! But very low in Iodine.
Get some Iodoral or Lugols
and give it a try.
get all the other companion nutrients
I personally do much better on higher dosages...I am currently taking 150mg Iodoral per day.
when I first started I took 50mg of Iodoral for awhile and felt great...then yucky symptoms, then I lowered my dose and I wasn't reading enough here so I was only partially educated and scared. I kept backing off my dose and I kept having symptoms. Then i gave up on Iodine
and I got all into Colloidal Silver
for a year until that fell apart. Then I got back into Iodine
and I tried taking 100mg and I felt better than taking 50mg. Now it is 1 1/4 years on high doses of Iodine
and I am finally started to get more solid. and less detox from Iodine.
Of course I am doing liver flushes,chelating, killing pathogens, CEs, colonics, liver herbs, kiling candida, and a lot more. But that is my path, you have to find yours.......
