Thorne Thyroid Health Complex

Thyroid hormone starts with two raw materials, iodine and the amino acid tyrosine, and your body can't build T4 without both present in adequate amounts. Thorne's Thyroid Health Complex combines those two building blocks with the cofactors needed for the next step, converting T4 into active T3, plus a standardized ashwagandha extract and supporting vitamins in one daily formula.

Supports hormone formation – Iodine and L-tyrosine supply the raw materials for T4 production, while selenium, zinc, and copper support the separate step of converting T4 into active T3.

Chelated minerals for better absorption – Zinc and copper are delivered as Albion TRAACS bisglycinate chelates, a form built for better absorption than standard mineral salts.

Adds an adaptogen layer – KSM-66 ashwagandha is included alongside the core thyroid cofactors, and animal research has suggested it may support T4 levels, though that hasn't been established the same way in human studies.

Thyroid hormone regulates how your body metabolizes protein, fat, and carbohydrate into usable energy, which is why thyroid status touches so many systems at once. Iodine and tyrosine are the direct precursors to T4, while selenium, zinc, and copper are required cofactors for the enzymes that convert T4 into T3, the form your cells actually use. Vitamin C and vitamin E are included as antioxidants, since oxidative stress can interfere with that conversion process, and vitamin B12 is included because a deficiency in it can interfere with how thyroid hormone functions once it's made.
