Managing hyperthyroidism can be challenging, but there are some dietary strategies and supplements that might support your efforts:

1. Selenium: This micronutrient is important for thyroid health. Selenium is necessary for the metabolism of thyroid hormones and has antioxidant properties. It has been found beneficial for managing autoimmune thyroid diseases, particularly in reducing antithyroperoxidase antibody levels and potentially improving symptoms associated with thyroid disorders¹².

2. l-Carnitine: This is another supplement that might be helpful in managing hyperthyroidism. l-Carnitine has been reported to help with muscle weakness and fatigue, which are common in hyperthyroid patients. It acts as an antagonist of thyroid hormone activity on the heart and muscles³.

3. Avoid High Iodine Intake: Since you mentioned already avoiding high iodine foods like sea moss and seaweed, it’s essential to maintain this practice, as excessive iodine can exacerbate hyperthyroidism.

4. Myoinositol and Other Nutraceuticals: Myoinositol, along with selenium, can improve the function of the thyroid gland and help in modulating autoimmune processes. However, this combination's precise efficacy might vary among individuals⁴.

5. Vitamin D and B12: Certain studies have shown these vitamins play a role in regulating thyroid function, though they are generally more associated with hypothyroidism management. Ensuring adequate levels might support overall thyroid health⁵.

It's important to consult with a healthcare provider before starting any new supplement regimen, as they can provide guidance tailored to your specific health needs.
