NOW Thyroid Energy 90 Vege Capsules – Iodine, Selenium, Tyrosine & Ashwagandha for Thyroid Function & Metabolism
NOW Thyroid Energy 90 Vege Capsules – Iodine, Selenium, Tyrosine & Ashwagandha for Thyroid Function & Metabolism
NOW Thyroid Energy is a comprehensive nutritional formula designed to support healthy thyroid function and metabolism. The formula combines iodine (from kelp) and selenium — the two minerals most critical for thyroid hormone production and conversion — with L-Tyrosine (the amino acid backbone of thyroid hormones), Ashwagandha (an adaptogen that supports thyroid hormone levels under stress), and Guggul Extract (traditionally used in Ayurvedic medicine for thyroid and metabolic support). GMP certified, non-GMO. 90 vege capsules.
- Iodine (from kelp) — essential for T3 and T4 thyroid hormone synthesis
- Selenium — required for T4-to-T3 conversion (the active hormone)
- L-Tyrosine — amino acid backbone of thyroid hormones
- Ashwagandha — adaptogen that supports thyroid hormone levels
- 90 vege capsules — GMP certified, non-GMO
Frequently Asked Questions
Why do thyroid hormones need iodine AND selenium?
Iodine is incorporated directly into the structure of thyroid hormones — T4 (thyroxine) contains 4 iodine atoms and T3 (triiodothyronine) contains 3. Without adequate iodine, the thyroid gland cannot produce sufficient hormones. Selenium is required for the enzyme deiodinase that converts the less-active T4 into the metabolically active T3 in peripheral tissues. Both minerals are therefore essential — iodine for hormone production, selenium for activation. New Zealand soils are selenium-deficient, making supplementation particularly relevant for NZ residents.
What role does Tyrosine play in thyroid hormone production?
L-Tyrosine is literally the molecular scaffold of thyroid hormones — both T4 and T3 are built by attaching iodine atoms to tyrosine residues on thyroglobulin (the thyroid's storage protein). Without adequate tyrosine, the thyroid cannot assemble hormone molecules even with sufficient iodine. Supplemental tyrosine ensures this building block is available alongside iodine and selenium.
Is NOW Thyroid Energy suitable for people with diagnosed hypothyroidism taking levothyroxine?
Consult your endocrinologist or GP before adding thyroid supplements alongside levothyroxine. Iodine and other thyroid-active nutrients can influence thyroid function tests and potentially interact with prescribed thyroid hormone replacement. This supplement is more appropriate as nutritional support for subclinical thyroid concerns or preventive nutritional support — not as a substitute for prescribed thyroid medication.
What is Ashwagandha's role in thyroid health?
Several clinical studies show Ashwagandha supplementation modestly increases T3 and T4 levels in people with subclinical hypothyroidism, while simultaneously reducing TSH (thyroid-stimulating hormone). The mechanism appears to involve reduced cortisol-mediated suppression of thyroid hormone production — chronic stress and elevated cortisol impair T4-to-T3 conversion, and Ashwagandha's adaptogenic cortisol-lowering effects partially restore this conversion.
How long until NOW Thyroid Energy shows results?
Nutritional thyroid support typically requires 6–12 weeks of consistent daily use before meaningful improvements in thyroid function markers are detectable on blood tests. Subjective improvements in energy, metabolism, and mood may be noticed within 4–6 weeks. For objective assessment, test TSH, free T3, and free T4 before starting and after 12 weeks of supplementation.
