Thyroid Support Herbs: What Works and what to watch for
Struggling with low energy, weight changes, or a racing heart? Some herbs can help support thyroid function or ease symptoms. But not every plant is safe for everyone. Below you’ll find practical options, short notes on the evidence, and clear warnings so you can make smarter choices.
Top herbs people use for thyroid support
Ashwagandha — an adaptogen often used for low thyroid (hypothyroid). Small clinical trials show ashwagandha can lower TSH and raise T4 in people with subclinical hypothyroidism. Typical doses are 300–600 mg of a standardized extract once or twice daily. Watch for overstimulation if you already take thyroid hormone.
Guggul (Commiphora mukul) — traditionally used in Ayurvedic medicine to boost metabolism. Some studies suggest guggul can increase thyroid activity, but results vary. Standardized extracts, taken as directed on the label, are safer than random raw resin. Avoid if you’re on thyroid meds without doctor guidance.
Bladderwrack (Fucus vesiculosus) — a seaweed high in iodine. It can help iodine-deficient hypothyroidism, but too much iodine makes autoimmune thyroid problems worse. Only consider this if blood tests show low iodine and under medical supervision.
Lemon balm (Melissa officinalis) and Bugleweed (Lycopus spp.) — these are used to calm symptoms of hyperthyroidism (overactive thyroid) like palpitations and anxiety. They act mildly to reduce thyroid hormone effects and are typically used short-term. If you have Graves’ disease or significant hyperthyroidism, stick to prescribed treatments first.
How to use thyroid herbs safely
Always get baseline labs before starting any herb: TSH, free T4, free T3, and antibodies (TPO, TgAb) if autoimmune disease is suspected. Herbs can shift hormone levels — sometimes fast. Recheck labs at 6–12 weeks after starting or changing a supplement.
Timing matters: take thyroid meds (like levothyroxine) on an empty stomach 30–60 minutes before food and at least 3–4 hours away from iron, calcium, and some herbs. Start low and increase slowly. If you feel jittery, sweaty, or extremely tired, stop and test.
Quality control is key. Use standardized extracts from reputable brands that show third‑party testing. Avoid homemade seaweed doses or unknown herbal blends that list vague ingredient amounts.
High-risk groups — pregnant or breastfeeding people, children, and those with serious heart disease — should avoid self-prescribing herbs for thyroid function. If you have autoimmune thyroid disease, get guidance from an endocrinologist or an experienced clinician familiar with herbal therapies.
Herbs can help, but they’re not a magic fix. Use tests, watch how you feel, and work with a clinician if you’re on medication. Small, careful steps often give the best results without surprises.
