I've read lots of your work on Iodine and I appreciate all of the time and energy you have put into your work. I've looked into low hydrochloric acid in the stomach and from what i've read if you have low hcla then no matter what you supplement with, vitamins and nutrients will not be absorbed properly nor from food or supplements. So i'm thinking to maybe do a test to see if it is low, then try to bring it back up and then maybe think about supplements such as vitamin d3, zinc etc.
