Re: Do these supplements help with Hypothyroid?

I like those also and take supplements from all of them with the exception thus far of New Chapter.  However, no one except Standard Process, which is generally more highly regarded by far than those you mentioned, has that particular product.  Standard Process products are not nearly as widely available (outside chiropractors and other health professionals that is) as most other supplements - they pretty well restrict their sales to professionals and a few select other outlets.

Another favorite of mine with outstanding products is Garden of Life.  Jon Barron formulas are also at the top in my opinion.
