Research Area: Thyroid
9 ingredients studied for effects on Thyroid — sorted by research relevance.
Vitamin B7 (Biotin)
Biotin is essential but deficiency is rare. For hair and nails only truly beneficial if a deficiency exists – plus lab values can be distorted.
Calcium
Essential mineral for bones, muscles, and nerves. Meta-analyses show moderate bone effects in deficiency; high-dose supplements carry cardiovascular risks.
Apigenin
Apigenin is a flavonoid from chamomile and parsley that inhibits CD38, an enzyme that degrades NAD+. Complements NMN/NR approaches. Early human evidence.
Ashwagandha (Withania somnifera)
Ashwagandha is an Ayurvedic adaptogen backed by multiple RCTs for stress and cortisol reduction. Sleep and testosterone effects are promising but come from small studies.
Sulforaphan
Sulforaphan activates Nrf2-dependent defence mechanisms and is typically sourced from broccoli sprouts. Strong preclinical evidence; clinical data still building.
Selen
Selenium is essential for glutathione peroxidases and thyroid hormones. In Germany and Austria, selenium supply is structurally low due to selenium-depleted soils.
Jod
Iodine is essential for thyroid hormones and cognitive development. Germany faces structural deficiency despite salt iodization. EFSA-approved claims.
L-Tyrosin
L-Tyrosin is an amino acid precursor of dopamine, noradrenaline, and adrenaline. Studies show cognitive benefits under acute stress and sleep deprivation.
Irish Sea Moss
Irish Sea Moss is a red algae marketed as a natural mineral source. Viral on social media but virtually no clinical evidence for health benefits.
