In this short interview, McCall McPherson explains the Thyroid Shield supplement, a formulation that combines myo‑inositol and selenium. She cites longstanding research showing selenium can lower thyroid‑autoantibody levels in Hashimoto’s disease and highlights newer studies indicating that adding myo‑inositol further enhances thyroid signaling, improves TSH feedback, and amplifies antibody reduction. McPherson recommends a monitoring protocol: test TPO and thyroglobulin antibodies at baseline (day 0) and retest after 90–120 days of taking Thyroid Shield to objectively assess changes. She notes the supplement is designed for anyone, not just clinic patients, and can be safely used alongside prescribed thyroid medication, though it is not medical advice. The overall message is that the synergistic combination offers a “win‑win‑win” for reducing antibodies, improving symptoms like fatigue, brain fog, and weight gain, and supporting overall thyroid health.

one of our top supplements that we recommend is thyroid support, right? Thyroid Shield is our thyroid supplement that we currently have in our store. Give us a little bit more education around how these particular ingredients help work alongside with our thyroid protocols.
So it's a combination of myo-inositol and selenium together. And definitely there have been historical studies that look at selenium in particular to help with activation of your thyroid hormones. But it's really measurably pretty powerful to look for reductions in antibodies of Hashimoto's, right? The autoimmune component of thyroid dysfunction, Hashimoto's. So we love to test this on day 0 and then retest it again on day 90 and look, because the data is objective, it's measurable. So that has existed in a long time, for a long time, but Newer research is combining myo-inositol and selenium and showing more promising results to just sensitize thyroid signaling, make your thyroid work better, make your feedback mechanism to adjust your TSH better. Also an improved outcome in the reduction of antibodies. So it's like it creates this synergistic win-win-win. And obviously people come to us to help With their symptoms of thyroid dysfunction, their fatigue, their brain fog, their weight gain, all of those things. But a lot of people particularly choose Modern Thyroid Clinic because they want to work on the reversal of their antibodies. And this is something that's accessible to everyone, right? Not just our patients. The dosing, the formulation is made for this specific purpose. And so even if someone isn't our patient, they can take this. And again, I would encourage them, look, test your antibodies, your TPO and thyroglobulin antibodies on day zero. Retest them 90, 120 days later after you've started ThyroShield, because I think you'll be surprised not only in the shift in how you feel, but also the reduction in your antibodies.
And this is something that they can safely take with their thyroid medication too, right? Not medical advice, but yes, we use it in conjunction with thyroid medication.
