Dr. Westin Childs

Dr. Westin Childs T3 Conversion Booster - Thyroid Support for Women & Men with Hypothyroidism & Hashimoto’s, Iodine, Ashwagandha, Guggul Extract, Selenium & Zinc Complex, 60 Servings

Dr. Westin Childs

$43.99

More Details
Main highlights
- T3 SUPPORT FOR THYROID PATIENTS - T3 is the most important thyroid hormone. This special blend helps the body naturally create more T3 directly in the thyroid gland and peripherally in the tissues. Very few supplements focus on T3 levels and instead support T4 thyroid hormone which is inactive. T3 support is ideal for men, women, and those with all thyroid conditions such as Hashimoto’s, thyroid removal, thyroidectomy, RAI, and hypothyroidism.
- SUPPORT ENERGY - The thyroid and adrenal glands are closely linked! You can’t support one without thinking about the other. For this reason, T3 Conversion Booster contains ashwagandha which acts as an adrenal adaptogen for cortisol support. Can be used in cases of high cortisol and low cortisol.
- NATURALLY ENHANCE T4 TO T3 CONVERSION - Ingredients such as zinc, selenium, and guggul extract help deiodinase enzymes create T3 thyroid hormone or triiodothyronine. But that’s not all. Vitamin A and Vitamin E are also included to help with thyroid cellular sensitivity and thyroid resistance. So once the body creates T3 it can actually use it in your cells!
- IODINE SUPPLEMENT - Natural sources of iodine in the form of kelp are also included in this formula! Iodine is essential for thyroid health and is required by all humans. Iodine is safe to use when combined with selenium which protects against thyroid gland damage.
- CLEAN SUPPLEMENTS & CLEAN INGREDIENTS - T3 Conversion Booster is gluten-free, dairy-free, soy-free, GMO-free, and free of artificial colors, sweeteners, and preservatives. It is made in the USA in a GMP-certified facility and undergoes third-party testing for heavy metals, mold, and microbes.
