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
