ThyroVantage HT (90)

Feature Summary

Subclinical hypothyroidism is present in 10% of the adult population and, if untreated, it increases the risk for cardiovascular disease.^1–3 As an adjunct to prescriptive treatment, ThyroVantage HT provides the nutritional building blocks for healthy thyroid hormone production, including L-tyrosine, an important nutritional precursor for thyroxine (T4). It also provides catecholamines, such as norepinephrine and dopamine, as supplementation has been shown to mitigate periods of stress.^4,5 Potassium iodide provides iodine, which is critical to thyroid hormone formation and is deficient in 15–23% of women.^6,7 Iodine supplementation among women with iodine deficiency has been shown to reduce both TSH and cholesterol levels.⁸

ThyroVantage HT includes two herbs known to stimulate thyroid function: Commiphora mukul, shown to enhance T3 formation in animal studies, and Withania somnifera, which significantly improved TSH, T3, and T4 levels in patients with subclinical hypothyroidism in a prospective randomized and controlled trial.^9–12 Selenium (as selenomethionine) is also included, as supplementation has been shown to reduce thyroid autoantibody levels (thyroid peroxidase) among adults, both when combined with levothyroxine and when given alone.¹³ Pantothenic acid provides additional adrenal support, with the minerals copper and manganese providing cofactor support for thyroid function.^14–16
