Terry Naturally Thyroid Care features L-Tyrosine for cognitive and thyroid support, but contains an alarmingly high dose of iodine (30,000 mcg), which significantly surpasses safe intake levels and carries substantial risks for thyroid dysfunction and overall health.
This 'Thyroid Care' product combines L-Tyrosine (400mg) with a profoundly excessive dose of iodine (30,000 mcg). While L-Tyrosine is a valuable amino acid for supporting thyroid hormone synthesis and neurotransmitter production, the iodine content is the primary and most concerning aspect. The Recommended Dietary Allowance (RDA) for iodine is 150 mcg for adults, and the Tolerable Upper Intake Level (UL) is 1,100 mcg. Consuming 30 mg of iodine daily is nearly 30 times the UL, a level widely considered dangerous by mainstream nutritionists and medical professionals. Such high doses can lead to severe thyroid imbalances, including both hyperthyroidism (Jod-Basedow phenomenon) and hypothyroidism (Wolff-Chaikoff effect), particularly in susceptible individuals. Online reviews may vary, but the scientific evidence strongly cautions against iodine intake at this magnitude without direct and intensive medical supervision and specific clinical indication, which is rare. The potential benefits from L-Tyrosine are overshadowed by the significant health risks posed by the iodine dosage.
