What Are the Side Effects of Clean Nutraceuticals Thyro Defend?
Always consult your health practitioner if in doubt.
RiskMedium Risk
Overview
•High iodine (500 mcg) and selenium (300 mcg) doses exceed typical daily needs and may disrupt thyroid function in sensitive individuals or those with autoimmune thyroid disease.
•Zinc at 50 mg per serving is well above the tolerable upper intake level of 40 mg and can cause nausea, copper imbalance, or immune suppression with prolonged use.
•Magnesium at 250 mg is generally safe but oxide form may cause loose stools; combined with high-dose vitamins A and D3 requires monitoring to avoid hypervitaminosis.
•Ashwagandha, L-tyrosine, and herbal extracts are usually well-tolerated but may interact with thyroid medications, sedatives, or blood thinners.
•Not recommended during pregnancy or breastfeeding due to high iodine, selenium, and botanical content; consult physician before use if on levothyroxine or with hyperthyroidism.
•Bovine gelatin capsules present an allergen risk for those with beef or gelatin sensitivities.

Dosage & Bioavailability
How the active doses and forms in Thyro Defend compare to the research.
•Selenium (as selenium glycinate) — 300 mcg per serving; above the 55-200 mcg range commonly studied for thyroid conversion, glycinate form offers good absorption.
•Iodine (as potassium iodide) — 500 mcg per serving; exceeds standard 150 mcg RDA and typical 150-225 mcg supplemental ranges, iodide form is highly bioavailable.
•Zinc (as zinc oxide) — 50 mg per serving; at the upper limit of studied ranges but oxide form shows lower absorption than chelates.
