Osterly Market Thyroid Support Complex – Iodine Selenium Zinc Formula

Iodine, selenium, zinc, L-tyrosine and ashwagandha, each named.

A thyroid support formula with every ingredient dosed on the panel — and a genuine caution attached.

What it's for

Your thyroid needs iodine and the amino acid tyrosine to build thyroid hormone, and selenium to convert T4 into the active T3. Those are real, specific roles. What that does not mean is that adding more of them to a working thyroid makes it work better. For most people with normal thyroid function, this does very little.

How to take it

• Follow the label dose with food
• Take it four hours apart from any thyroid medication — minerals block absorption of levothyroxine
• Do not start this without knowing your thyroid status. Extra iodine can worsen both overactive and underactive thyroid conditions, and can trigger problems in Hashimoto's
• Selenium stacks with whatever is in your multivitamin. The upper limit is 400 mcg a day

On the label

• Iodine, selenium, zinc, L-tyrosine and ashwagandha, each dosed

What this is not

• Not a treatment for hypothyroidism
• Not a substitute for thyroid medication
• Not safe to take blind if you have a thyroid condition

The straight answer

Thyroid symptoms — fatigue, weight change, feeling cold — overlap with a dozen other things and need a blood test, not a guess. If you have not had one, that is the better first step.
