A thyroid support supplement with L-Tyrosine and an extremely high, potentially toxic dose of Iodine, making it generally unsafe.

Quantity: 60
Analysis

This 'Thyroid Care' product, sharing the exact formulation with its 60-count counterpart, includes L-Tyrosine (400mg) and an alarming 30,000 mcg (30 mg) of Iodine. While the L-Tyrosine component is beneficial for supporting cognitive functions, focus, and mood by acting as a precursor for key neurotransmitters, the iodine dosage presents a critical safety concern. This amount of iodine is vastly beyond safe daily intake levels and carries a substantial risk of inducing severe thyroid disorders and other adverse health effects, directly counteracting its purported benefits for general health and metabolism. The considerable risk of iodine toxicity makes this product highly questionable for regular use.

Pros
  • Contains L-Tyrosine at a beneficial dosage for supporting cognitive and mood functions.
  • Offers a larger quantity of servings at a more economical price per serving ($0.20) compared to the smaller bottle.
Cons
  • Features an excessively high and potentially lethal Iodine dosage (30,000 mcg) which is far above safe consumption levels.
  • The formulation lacks other essential micronutrients such as selenium and zinc, which are crucial for optimal thyroid hormone conversion and overall thyroid health.
  • The dangerously high iodine content is prone to disrupt, rather than enhance, healthy metabolic functions and overall well-being.
Warnings
  • The Iodine dosage of 30,000 mcg (30 mg) is critically toxic and could lead to acute medical emergencies or chronic severe thyroid imbalances, including both hyper- and hypothyroidism.
  • Due to the extreme and hazardous nature of the listed iodine content, this product should be avoided for all but very specific and rare medical indications under stringent professional supervision.

Categories
Tyrosine 60.0
The L-Tyrosine component is adequately dosed, but its beneficial effects are severely undermined by the extreme and hazardous concentration of iodine in the formulation.
Iodine 0.0
The iodine dosage is dangerously excessive and completely inappropriate for supplementation, making the product a severe liability within the iodine category.
Goals
Brain Health 10.0
Although L-Tyrosine supports brain health, the potential for severe adverse reactions from iodine overdose could negatively impact cognitive function and neurological stability.
Mental Focus 10.0
Despite L-Tyrosine's role in supporting focus, the systemic consequences of iodine toxicity could lead to symptoms that severely impede concentration and mental clarity.
Mood Support 10.0
While L-Tyrosine contributes to positive mood, the severe physiological disturbances from excessive iodine could provoke mood swings, heightened anxiety, or depressive symptoms.
