Welcome to the Optimal Thyroid Levels calculator. Now you can go beyond the one size fits all approaches behind 'normal levels' and even 'optimal levels.' Many factors go into which thyroid levels will be best for you. This is the first online tool that will take into account your individual needs and help you find your best thyroid levels.

The benefit of knowing your best levels is that you can have your best odds of reversing ongoing thyroid symptoms and that you can be sure that your thyroid treatment is safe.

If you are already at your best levels, you will have the clarity of knowing that any remaining symptoms may not be thyroid related.
