Thyroid levels

I mentioned before that I'd been having some issues with throat, tongue issues, swallowing, shortness of breath, vagus nerve irritation and loads more since treating babs. It was suggested I get a thyroid test which I did. It came back within range at 0.4 (tsh) this was the only thyroid test done. Is it worth getting something natural to support the thyroid even though I am in range to see if it will help alleviate some symptoms?
