Taking black seed oil daily can help provide support to the immune system providing root cause management. Research also indicates it may provide balance to the TSH, free T3, and free T4 levels.*
SUPPORT FOR THYROID ANTIBODIES - One double-blind placebo-controlled trial showed that taking nigella sativa daily may provide support to those with elevated thyroglobulin antibodies, elevated TSH, and elevated thyroid peroxidase antibodies over 8 weeks.*
EASIER TO TAKE THAN BLACK SEED OIL - Black seed oil comes from black cumin seeds that are cold pressed and contains many of the same ingredients as nigella sativa powder, but has one major downside: its taste and flavor.

WITH MYO INOSITOL & SELENIUM - Myo inositol is a sugar alcohol that has been shown to help with TSH signaling (thyroid cell signaling) and selenium is used by the body to create glutathione. Taken together, these ingredients support healthy TPO and thyroglobulin levels, a healthy TSH, and healthy free T4 and free T3.

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

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 Hashimotos, thyroid removal, thyroidectomy, RAI, and hypothyroidism.
NATURALLY ENHANCE T4 TO T3 CONVERSION - Ingredients such as zinc, selenium, and guggul extract help deiodinase enzymes create T3 thyroid hormone or triiodothyronine. But thats 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!
SUPPORT ENERGY - The thyroid and adrenal glands are closely linked! You cant 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.
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.
