Which symptoms are bothering you the most?
Pick up to 3.

What treatment are you on right now?

This is the question that changes your first pick, so answer it honestly.
Do you prefer pills or creams, oils, and powders?
How it works
How This Quiz Works
Hyperthyroidism flips the usual thyroid supplement playbook upside down. Most thyroid supplements are made to support hormone production, and that’s the last thing you want more of right now.
So this quiz screens them out. Anything that supports thyroid hormone production stays off your list while you’re hyper, and what’s left is chosen for what an overactive thyroid actually burns through: your minerals, your stress response, your muscle, and your sleep.
One thing this quiz will never do is replace your treatment. An overactive thyroid is a medical problem, and methimazole, PTU, RAI, and surgery are how it gets controlled. Supplements support you through that. They don’t do the controlling.
The logic
Why Your First Pick Depends On Your Answers
If your hyperthyroidism comes from Graves’ disease, it’s autoimmune, and the antibodies are the cause. That’s why your first pick targets the immune response.
If you’re still racing and wired, your stress system is carrying the load, and supporting it comes first while your medication brings your levels down.
And if you already had RAI or surgery and swung hypo, you’re not a hyperthyroid patient anymore. You’re an underactive thyroid patient now, and your picks change completely to match.
Common questions
Frequently Asked Questions
No, and be suspicious of anyone who says otherwise. An overactive thyroid can stress your heart and your bones, and it needs real treatment: methimazole, PTU, radioactive iodine, or surgery. What supplements can do is support the systems hyperthyroidism drains while your treatment works: your minerals, your sleep, your stress response, and your muscle mass.
Because most thyroid supplements support hormone production, and your thyroid is already making too much. Anything with glandular tissue, T2, or conversion support stays off your list while you’re hyper. If your treatment eventually swings you hypo, which is common after RAI or surgery, those become useful, and the quiz handles that if you re-take it.
No. Iodine is fuel for hormone production, and adding fuel to an overactive gland can make things worse. Skip kelp and standalone iodine supplements entirely until your thyroid is controlled and your doctor says otherwise.
Tell your doctor first, because a racing heart from hyperthyroidism is what beta blockers exist for. Alongside that, magnesium is the mineral an overactive thyroid burns through fastest, and low magnesium makes palpitations, tremor, and anxiety all louder.
