Best Thyroid Supplements for Women Recommended in Clinic (And Which Ones to Avoid)

If you have been told your thyroid labs are "normal" but you still feel exhausted, foggy, or off in your body, you are not imagining it. Thyroid health plays a major role in regulating metabolism, mood, weight, energy, and even your menstrual cycle. When your thyroid is not functioning optimally, everything else can feel out of sync.

Symptoms like fatigue, dry skin, anxiety, weight gain, poor concentration, and irregular periods are often brushed off or blamed on stress or aging. Many women are dismissed because their labs fall within a standard reference range, even when their symptoms are persistent and real.

This is where functional medicine comes in. Instead of looking at just one or two thyroid markers, we dig deeper with a full panel including TSH, free T3, free T4, reverse T3, and thyroid antibodies. These tests reveal subtle dysfunctions that standard labs often miss and help uncover if your thyroid issues are tied to stress, gut imbalances, or autoimmunity.

Not every supplement works for every woman. In fact, taking the wrong supplement without understanding the root cause can make symptoms worse. That is why a personalized, functional approach is essential. Learn more about functional thyroid support for women in Michigan at Elle MD.

Supplements to be cautious about or avoid

Iodine in high doses While iodine is essential for thyroid function, too much can worsen or trigger thyroid dysfunction, especially for those with Hashimoto’s. Many over-the-counter supplements contain excessive iodine without clear labeling. If you are already consuming iodine through food and a multivitamin, adding more may backfire.

Thyroid glandulars These are made from dried animal thyroid tissue and may contain active hormones. They are unregulated and can interfere with your thyroid medication or disrupt your natural hormone production. They may promise a "natural" solution, but they carry serious risks.

Biotin in large amounts Biotin does not directly affect thyroid function, but it can skew lab test results and make it harder for your provider to get accurate readings. High doses may make your labs look normal when they are not. Always disclose what you are taking before lab work. 

How to reset your thyroid naturally

To support your thyroid naturally, focus first on diet and lifestyle. Eat selenium-rich foods (like Brazil nuts), hydrate well, and manage stress through gentle movement, mindfulness, and proper rest. 

When to seek functional medicine and support your thyroid with a personalized plan?

If you are experiencing ongoing fatigue, hair loss, weight struggles, anxiety, or cold intolerance, it is time to investigate what is really going on. These symptoms may point to a deeper thyroid or hormonal imbalance.

Functional medicine takes a full-spectrum approach. Instead of stopping at TSH, we assess free T3, free T4, reverse T3, and thyroid antibodies—along with nutrient levels like vitamin D, iron, and selenium. From there, we build a supplement protocol tailored to your needs and symptoms, not a one-size-fits-all formula.
