I recommend looking at the details and use of Himalayan salt mixed with raw honey on your browser. I have been taking the 3 to 1 mix every night under the tongue for the last two months and my last blood test for Thyroid function showed a significant elevation in T4 and my GP reduced my daily intake from 100mcg to 75mcg pending a further test in six weeks. I will post results then. I have been interested in the posts from other hypothyroid patients indicating adrenal gland deficiences have bearing on thyroid function and believe that the salt/honey mix has helped to activate my adrenals. I certainly have much more energy and I'm sleeping well again.
