Tyrosine serves as a precursor for thyroid hormones and catecholamines, which may support hormone synthesis and metabolic signalling.
Caution: May interact with thyroid medications and stimulants; start with food to reduce potential stomach discomfort.
Iodine is incorporated into thyroxine (T4) and triiodothyronine (T3), which are key hormones that regulate metabolic activity.
Caution: Excess iodine may affect thyroid function, especially in those with thyroid concerns; avoid combining with other high-iodine supplements unless advised.
Withanolides are studied for supporting stress adaptation, which may influence the body’s response to daily demands and energy levels.
Caution: May cause drowsiness in some and interact with sedatives; take earlier in the day to assess tolerance.
Zinc acts as a cofactor for enzymes involved in hormone conversion and antioxidant defences that support cellular function.
Caution: High-dose zinc may cause nausea on an empty stomach and can reduce copper status over time; take with food.
Selenium supports enzymes such as iodothyronine deiodinases that convert T4 to the more active T3.
Caution: Do not combine with multiple selenium-containing products to avoid excessive intake.
Tyrosine and iodine provide the building blocks for thyroid hormone synthesis, while selenium and zinc support hormone conversion and enzyme function. Ashwagandha complements these nutrients by supporting the body’s stress response, which is closely linked to perceived energy and daily resilience.
Label Warning: Consult a healthcare practitioner before use if taking thyroid, mood-altering, or central nervous system depressant medicines. Not intended for pregnant or breastfeeding women. Avoid use if you have inborn errors of metabolism involving tyrosine, including alkaptonuria and tyrosinaemia types I and II. If you have a thyroid disorder or a known stomach ulcer, consult a healthcare practitioner before use. May cause mild, temporary gastrointestinal upset; stop use if symptoms persist. Stop use if rash or itching occurs.
Who should be cautious: People with thyroid conditions, stomach ulcers, or inborn errors of tyrosine metabolism. Those using mood-altering or central nervous system depressant medicines.
