Thyroid health, energy and metabolism, stress support
Adults with busy, high-stress routines or those with low dietary intake of iodine-rich foods like sea vegetables and dairy.
Take 2 capsules once daily, with or without food; if sensitive, consider taking with a meal.
Gluten Free. No artificial colours, flavours, or preservatives. No yeast, eggs, fish, shellfish, peanuts, tree nuts, wheat, milk, or magnesium stearate. May contain trace quantities of very small fish and/or crustacean shellfish from kelp source.
Withanolides interact with stress response pathways and may help modulate cortisol and support a balanced hypothalamic–pituitary–thyroid axis.
Caution: May cause drowsiness or gastrointestinal upset in some people; check for interactions if using sedatives or thyroid-related supplements.
L-tyrosine is a precursor to the amino acid backbone used to form thyroid hormones and catecholamines.
Caution: May cause jitteriness in sensitive individuals; avoid taking with large amounts of caffeine.
Iodine is incorporated into thyroxine (T4) and triiodothyronine (T3), enabling normal thyroid hormone synthesis.
Caution: Excess iodine intake may be uncomfortable for those sensitive to iodine; monitor total iodine from diet and supplements.
Selenium is a cofactor for deiodinase enzymes that convert T4 to the more active T3 and supports antioxidant defences in the thyroid.
Caution: High intakes may cause nausea or hair and nail changes; consider total selenium from all sources.
Forskolin activates adenylate cyclase, increasing cyclic AMP which may influence cellular metabolic signalling.
Caution: May lower blood pressure in some individuals; use caution if prone to light-headedness or taking blood pressure–related products.
Tyrosine and iodine provide core building blocks for thyroid hormone, while selenium supports the conversion of T4 to T3. Ashwagandha helps the stress response that can influence thyroid signalling, and forskolin modulates cellular messaging related to metabolism.
Label Warning: For adults. Use only as directed. If you are pregnant, nursing, taking medication, or under medical supervision for any condition, consult a healthcare professional before use.
Who should be cautious: People with thyroid conditions, on thyroid medications, or with iodine sensitivity may need extra caution due to iodine from kelp, guggul, ashwagandha, and bovine thyroid glandular. Those with shellfish or fish allergies should note the kelp extract may contain trace amounts of small fish or crustacean shellfish. People with autoimmune conditions, heart concerns, or on blood pressure or blood sugar medications should discuss use with a healthcare professional. If combining with thyroid medications, it is recommended to consult a healthcare provider before use.
Storage: Store in a cool, dry place. Keep out of reach of children.
